Method Detail
-
newTermState
public BlockTermState newTermState()
Description copied from class:PushPostingsWriterBase
Return a newly created empty TermState- Specified by:
newTermState
in classPushPostingsWriterBase
-
init
public void init(IndexOutput termsOut, SegmentWriteState state) throws java.io.IOException
Description copied from class:PostingsWriterBase
Called once after startup, before any terms have been added. Implementations typically write a header to the providedtermsOut
.- Specified by:
init
in classPostingsWriterBase
- Throws:
java.io.IOException
-
setField
public void setField(FieldInfo fieldInfo)
Description copied from class:PushPostingsWriterBase
Sets the current field for writing, and returns the fixed length of long[] metadata (which is fixed per field), called when the writing switches to another field.- Overrides:
setField
in classPushPostingsWriterBase
-
startTerm
public void startTerm(NumericDocValues norms)
Description copied from class:PushPostingsWriterBase
Start a new term. Note that a matching call toPushPostingsWriterBase.finishTerm(BlockTermState)
is done, only if the term has at least one document.- Specified by:
startTerm
in classPushPostingsWriterBase
-
startDoc
public void startDoc(int docID, int termDocFreq) throws java.io.IOException
Description copied from class:PushPostingsWriterBase
Adds a new doc in this term.freq
will be -1 when term frequencies are omitted for the field.- Specified by:
startDoc
in classPushPostingsWriterBase
- Throws:
java.io.IOException
-
addPosition
public void addPosition(int position, BytesRef payload, int startOffset, int endOffset) throws java.io.IOException
Description copied from class:PushPostingsWriterBase
Add a new position and payload, and start/end offset. A null payload means no payload; a non-null payload with zero length also means no payload. Caller may reuse theBytesRef
for the payload between calls (method must fully consume the payload).startOffset
andendOffset
will be -1 when offsets are not indexed.- Specified by:
addPosition
in classPushPostingsWriterBase
- Throws:
java.io.IOException
-
finishDoc
public void finishDoc() throws java.io.IOException
Description copied from class:PushPostingsWriterBase
Called when we are done adding positions and payloads for each doc.- Specified by:
finishDoc
in classPushPostingsWriterBase
- Throws:
java.io.IOException
-
finishTerm
public void finishTerm(BlockTermState _state) throws java.io.IOException
Called when we are done adding docs to this term- Specified by:
finishTerm
in classPushPostingsWriterBase
- Throws:
java.io.IOException
-
encodeTerm
public void encodeTerm(DataOutput out, FieldInfo fieldInfo, BlockTermState _state, boolean absolute) throws java.io.IOException
Description copied from class:PostingsWriterBase
Encode metadata as long[] and byte[].absolute
controls whether current term is delta encoded according to latest term. Usually elements inlongs
are file pointers, so each one always increases when a new term is consumed.out
is used to write generic bytes, which are not monotonic.- Specified by:
encodeTerm
in classPostingsWriterBase
- Throws:
java.io.IOException
-
close
public void close() throws java.io.IOException
- Specified by:
close
in interfacejava.lang.AutoCloseable
- Specified by:
close
in interfacejava.io.Closeable
- Specified by:
