Method Detail

performAdditionalChecks

protected void performAdditionalChecks()

Description copied from class: Operator

This method is invoked during the validation checks. It is invoked as a last check. The default implementation does nothing. Subclasses might want to override this method to perform some specialized checks, e.g. if an inner operator is of a specific class.

Overrides:

performAdditionalChecks in class Operator

doWork

public void doWork()
            throws UserError

Description copied from class: Operator

Performs the actual work of the operator and must be implemented by subclasses. Replaces the old method apply().

Overrides:

doWork in class Operator

Throws:

UserError

setReplaces

public void setReplaces(java.lang.String replaces)

getReplaces

public java.lang.String getReplaces()
