Interface Function<T1,T2>

Type Parameters:

T1 - The domain of the function

T2 - The range of the function

All Known Subinterfaces:

SerializableFunction<T1,T2>

All Known Implementing Classes:

AbstractTreebankParserParams.AnnotatePunctuationFunction, Americanize, Buckwalter, ChineseEscaper, IdentityFunction, LexicalizedParser, LinearGrammarSmoother, LowercaseFunction, Morphology, ObjectBank.PathToFileFunction, PTBEscapingProcessor

public interface Function<T1,T2>

An interface for classes that act as a function transforming one object to another.

Implementation note: A function by itself is not serializable. We do however also provide an interface SerializableFunction for the common case of a function that should be Serializable.
