Method Detail

matches

public boolean matches(java.util.List<java.lang.Object> args)

Description copied from interface: Executor

Returns true if the executor applies to the given arguments. Typically, your custom executor will implement this method to check for the proper number of arguments and the proper argument types.

Parameters:

args - the arguments passed to the executor.

Returns:

true if the executor knows how to handle the given arguments, false otherwise.

execute

public Lvalue execute(java.util.List<java.lang.Object> args,
                      TerpEvaluator eval,
                      TerpContext ctx)

Description copied from interface: Executor

Performs the executor's action on the given arguments in the given context. Typically, your custom executor will implement this method to provide its core functionality.

Parameters:

args - the arguments.

eval - the evaluator to use. Can frequently be null.

ctx - the context in which the execution occurs. Can frequently be null.

Returns:

the execution result.
