Overrides:

init in class Func

Throws:

java.lang.IllegalArgumentException - throws the exception if initialization fails to ensure correct job runtime environment.

Description copied from class: Func

The real implementation which should be provided by ancestors.

Overrides:

execImpl in class Func

toHTML
