Class StrLookup<V>

  • Type Parameters:
    V - the type of the values supported by the lookup
    All Implemented Interfaces:
    StringLookup
    Direct Known Subclasses:

    @Deprecated
    public abstract class StrLookup<V>
    extends java.lang.Object
    implements StringLookup
    Deprecated.
    Deprecated as of 1.3, use StringLookupFactory instead. This class will be removed in 2.0.
    Lookup a String key to a String value.

    This class represents the simplest form of a string to string map. It has a benefit over a map in that it can create the result on demand based on the key.

    This class comes complete with various factory methods. If these do not suffice, you can subclass and implement your own matcher.

    For example, it would be possible to implement a lookup that used the key as a primary key, and looked up the value on demand from the database

    Since:
    1.0
