Method Detail

data

public AUCData data()

init

protected void init()
             throws java.lang.IllegalArgumentException

Description copied from class: Func

Invoked before run. This is the place to checks arguments are valid or throw IllegalArgumentException. It will get invoked both from the Web and Java APIs.

Overrides:

init in class Func

Throws:

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

execImpl

protected void execImpl()

Description copied from class: Func

The real implementation which should be provided by ancestors.

Overrides:

execImpl in class Func

toHTML

public boolean toHTML(java.lang.StringBuilder sb)

Overrides:

toHTML in class Request

toASCII

public void toASCII(java.lang.StringBuilder sb)
