org.geoserver.script.function.FunctionHook

Hook for function objects.

This class is responsible for adapting a script into a function integrated into the geotools filter function subsystem. This base implementation will look for a function named "run" defined by the script, and invoke it with two arguments:

The value the function is to be evaluated for
A list of arguments derived from the parameters of the function

Script plugins should extend this class to implement custom behaviour. See {@link ScriptPlugin#createFunctionHook()}

Instances of this class must be thread safe.
