allowSimpleKey
private boolean allowSimpleKey
A simple key is a key that is not denoted by the '?' indicator. Example of simple keys: --- block simple key: value ? not a simple key: : { flow simple key: value } We emit the KEY token before all keys, so when we find a potential simple key, we try to locate the corresponding ':' indicator. Simple keys should be limited to a single line and 1024 characters. Can a simple key start at the current position? A simple key may start: - at the beginning of the line, not counting indentation spaces (in block context), - after '{', '[', ',' (in the flow context), - after '?', ':', '-' (in the block context). In the block context, this flag also signifies if a block collection may start at the current position.

-true
to parse;false
to ignore
-
isParseComments
@Deprecated public boolean isParseComments()
Deprecated.
-
checkToken
public boolean checkToken(Token.ID... choices)
Check whether the next token is one of the given types.- Specified by:
checkToken
in interfaceScanner
- Parameters:
choices
- token IDs to match with- Returns:
true
if the next token is one of the given types. Returnsfalse
if no more tokens are available.
-
peekToken
public Token peekToken()
Return the next token, but do not delete it from the queue.- Specified by:
peekToken
in interfaceScanner
- Returns:
- The token that will be returned on the next call to
Scanner.getToken()
-
getToken
public Token getToken()
Return the next token, removing it from the queue.
-
addToken
private void addToken(Token token)
-
addToken
private void addToken(int index, Token token)
-
addAllTokens
private void addAllTokens(java.util.List<Token> tokens)
-
needMoreTokens
private boolean needMoreTokens()
Returns true if more tokens should be scanned.
-
fetchMoreTokens
private void fetchMoreTokens()
Fetch one or more tokens from the StreamReader.
-
escapeChar
private java.lang.String escapeChar(java.lang.String chRepresentation)
This is implemented in CharConstants in SnakeYAML Engine
-
nextPossibleSimpleKey
private int nextPossibleSimpleKey()
Return the number of the nearest possible simple key. Actually we don't need to loop through the whole dictionary.
-
stalePossibleSimpleKeys
private void stalePossibleSimpleKeys()
Remove entries that are no longer possible simple keys. According to the YAML specification, simple keys - should be limited to a single line, - should be no longer than 1024 characters. Disabling this procedure will allow simple keys of any length and height (may cause problems if indentation is broken though).
-
savePossibleSimpleKey
private void savePossibleSimpleKey()
The next token may start a simple key. We check if it's possible and save its position. This function is called for ALIAS, ANCHOR, TAG, SCALAR(flow), '[', and '{'.
-
removePossibleSimpleKey
private void removePossibleSimpleKey()
Remove the saved possible key position at the current flow level.
-
unwindIndent
private void unwindIndent(int col)
* Handle implicitly ending multiple levels of block nodes by decreased indentation. This function becomes important on lines 4 and 7 of this example:1) book one: 2) part one: 3) chapter one 4) part two: 5) chapter one 6) chapter two 7) book two:
In flow context, tokens should respect indentation. Actually the condition should be `self.indent >= column` according to the spec. But this condition will prohibit intuitively correct constructions such as key : { }
-
addIndent
private boolean addIndent(int column)
Check if we need to increase indentation.
-
fetchStreamStart
private void fetchStreamStart()
We always add STREAM-START as the first token and STREAM-END as the last token.

scanToNextToken
private void scanToNextToken()
We ignore spaces, line breaks and comments. If we find a line break in the block context, we set the flag `allow_simple_key` on. The byte order mark is stripped if it's the first character in the stream. We do not yet support BOM inside the stream as the specification requires. Any such mark will be considered as a part of the document. TODO: We need to make tab handling rules more sane. A good rule is Tabs cannot precede tokens BLOCK-SEQUENCE-START, BLOCK-MAPPING-START, BLOCK-END, KEY(block), VALUE(block), BLOCK-ENTRY So the checking code is if <TAB>: self.allow_simple_keys = False We also need to add the check for `allow_simple_keys == True` to `unwind_indent` before issuing BLOCK-END. Scanners for block, flow, and plain scalars need to be modified.
-
scanComment
private CommentToken scanComment(CommentType type)
-
scanDirective
private java.util.List<Token> scanDirective()
-
scanDirectiveName
private java.lang.String scanDirectiveName(Mark startMark)
Scan a directive name. Directive names are a series of non-space characters.- See Also:
- 7.1. Directives
-
scanYamlDirectiveValue
private java.util.List<java.lang.Integer> scanYamlDirectiveValue(Mark startMark)
-
scanYamlDirectiveNumber
private java.lang.Integer scanYamlDirectiveNumber(Mark startMark)
Read a %YAML directive number: this is either the major or the minor part. Stop reading at a non-digit character (usually either '.' or '\n').- See Also:
- 7.1.1. “YAML” Directive,
-
scanTagDirectiveValue
private java.util.List<java.lang.String> scanTagDirectiveValue(Mark startMark)
Read a %TAG directive value:
s-ignored-space+ c-tag-handle s-ignored-space+ ns-tag-prefix s-l-comments
- See Also:
- 7.1.2. “TAG” Directive
-
scanTagDirectiveHandle
private java.lang.String scanTagDirectiveHandle(Mark startMark)
Scan a %TAG directive's handle. This is YAML's c-tag-handle.- Parameters:
startMark
- - beginning of the handle- Returns:
- scanned handle
- See Also:
- 7.1.2.2. Tag Handles
-
scanTagDirectivePrefix
private java.lang.String scanTagDirectivePrefix(Mark startMark)
Scan a %TAG directive's prefix. This is YAML's ns-tag-prefix.
-
scanDirectiveIgnoredLine
private CommentToken scanDirectiveIgnoredLine(Mark startMark)
-
scanAnchor
private Token scanAnchor(boolean isAnchor)
The YAML 1.1 specification does not restrict characters for anchors and aliases. This may lead to problems. see https://bitbucket.org/snakeyaml/snakeyaml/issues/485/alias-names-are-too-permissive-compared-to This implementation tries to follow https://github.com/yaml/yaml-spec/blob/master/rfc/RFC-0003.md
-
scanTag
private Token scanTag()
Scan a Tag property. A Tag property may be specified in one of three ways: c-verbatim-tag, c-ns-shorthand-tag, or c-ns-non-specific-tag
c-verbatim-tag takes the form !<ns-uri-char+> and must be delivered verbatim (as-is) to the application. In particular, verbatim tags are not subject to tag resolution.
c-ns-shorthand-tag is a valid tag handle followed by a non-empty suffix. If the tag handle is a c-primary-tag-handle ('!') then the suffix must have all exclamation marks properly URI-escaped (%21); otherwise, the string will look like a named tag handle: !foo!bar would be interpreted as (handle="!foo!", suffix="bar").
c-ns-non-specific-tag is always a lone '!'; this is only useful for plain scalars, where its specification means that the scalar MUST be resolved to have type tag:yaml.org,2002:str.
TODO SnakeYaml incorrectly ignores c-ns-non-specific-tag right now.- See Also:
- 8.2. Node Tags TODO Note that this method does not enforce rules about local versus global tags!
-
scanBlockScalar
private java.util.List<Token> scanBlockScalar(char style)
-
scanBlockScalarIndicators
private ScannerImpl.Chomping scanBlockScalarIndicators(Mark startMark)
Scan a block scalar indicator. The block scalar indicator includes two optional components, which may appear in either order. A block indentation indicator is a non-zero digit describing the indentation level of the block scalar to follow. This indentation is an additional number of spaces relative to the current indentation level. A block chomping indicator is a + or -, selecting the chomping mode away from the default (clip) to either -(strip) or +(keep).
-
scanBlockScalarIgnoredLine
private CommentToken scanBlockScalarIgnoredLine(Mark startMark)
Scan to the end of the line after a block scalar has been scanned; the only things that are permitted at this time are comments and spaces.
-
scanBlockScalarIndentation
private java.lang.Object[] scanBlockScalarIndentation()
Scans for the indentation of a block scalar implicitly. This mechanism is used only if the block did not explicitly state an indentation to be used.- See Also:
- 9.2.2. Block Indentation Indicator
-
scanBlockScalarBreaks
private java.lang.Object[] scanBlockScalarBreaks(int indent)
-
scanFlowScalar
private Token scanFlowScalar(char style)
Scan a flow-style scalar. Flow scalars are presented in one of two forms; first, a flow scalar may be a double-quoted string; second, a flow scalar may be a single-quoted string.- See Also:
- 9.1. Flow Scalar Styles style/syntax
See the specification for details. Note that we loose indentation rules for quoted scalars. Quoted scalars don't need to adhere indentation because " and ' clearly mark the beginning and the end of them. Therefore we are less restrictive then the specification requires. We only need to check that document separators are not included in scalars.
-
scanFlowScalarNonSpaces
private java.lang.String scanFlowScalarNonSpaces(boolean doubleQuoted, Mark startMark)
Scan some number of flow-scalar non-space characters.
-
scanFlowScalarSpaces
private java.lang.String scanFlowScalarSpaces(Mark startMark)
-
scanFlowScalarBreaks
private java.lang.String scanFlowScalarBreaks(Mark startMark)
-
scanPlain
private Token scanPlain()
Scan a plain scalar.See the specification for details. We add an additional restriction for the flow context: plain scalars in the flow context cannot contain ',', ':' and '?'. We also keep track of the `allow_simple_key` flag here. Indentation rules are loosed for the flow context.
-
atEndOfPlain
private boolean atEndOfPlain()
-
scanPlainSpaces
private java.lang.String scanPlainSpaces()
See the specification for details. SnakeYAML and libyaml allow tabs inside plain scalar
-
scanTagHandle
private java.lang.String scanTagHandle(java.lang.String name, Mark startMark)
Scan a Tag handle. A Tag handle takes one of three forms:
"!" (c-primary-tag-handle) "!!" (ns-secondary-tag-handle) "!(name)!" (c-named-tag-handle)
Where (name) must be formatted as an ns-word-char.
-
scanTagUri
private java.lang.String scanTagUri(java.lang.String name, Mark startMark)
Scan a Tag URI. This scanning is valid for both local and global tag directives, because both appear to be valid URIs as far as scanning is concerned. The difference may be distinguished later, in parsing. This method will scan for ns-uri-char*, which covers both cases.
This method performs no verification that the scanned URI conforms to any particular kind of URI specification.
-
scanUriEscapes
private java.lang.String scanUriEscapes(java.lang.String name, Mark startMark)
Scan a sequence of %-escaped URI escape codes and convert them into a String representing the unescaped values.
FIXME This method fails for more than 256 bytes' worth of URI-encoded characters in a row. Is this possible? Is this a use-case?- See Also:
- section 2.4, Escaped Encoding
-
scanLineBreak
private java.lang.String scanLineBreak()
Scan a line break, transforming:'\r\n' : '\n' '\r' : '\n' '\n' : '\n' '\x85' : '\n' default : ''
