Method Details

getFunction

public ScriptFunctionType getFunction(String name)

Description copied from interface: ScriptFunctionResolver

The same function must be returned if this is called again with the same name!

Specified by:

getFunction in interface ScriptFunctionResolver

Parameters:

name - the name to resolve.

Returns:

a corresponding function or null for no such function.
