Method Summary

UnaryFunction<A2,R>	bindFirst(A1 boundArgument) Answers a functor of one argument that evaluates in the same manner as this functor would if evaluated using a fixed first argument and another argument.
UnaryFunction<A1,R>	bindSecond(A2 boundArgument) Answers a functor of one argument that evaluates in the same manner as this functor would if evaluated using a fixed second argument and another argument.

Method Detail

bindFirst

public final UnaryFunction<A2,R> bindFirst(A1 boundArgument)

Answers a functor of one argument that evaluates in the same manner as this functor would if evaluated using a fixed first argument and another argument.

Parameters:

boundArgument - the fixed argument used as the first argument to this functor's evaluate method

Returns:

a functor that accepts one argument, of the same type as this functor's second argument type, that behaves as this functor would if always evaluated using boundArgument as the first argument

bindSecond

public final UnaryFunction<A1,R> bindSecond(A2 boundArgument)

Answers a functor of one argument that evaluates in the same manner as this functor would if evaluated using a fixed second argument and another argument.

Parameters:

boundArgument - the fixed argument used as the second argument to this functor's evaluate method

Returns:

a functor that accepts one argument, of the same type as this functor's first argument type, that behaves as this functor would if always evaluated using boundArgument as the second argument
