setSink

protected void setSink(Sink sink)

Overrides:

setSink in class TupleImpl

getRule

public RuleImpl getRule()

Retrieve the rule.

Specified by:

getRule in interface InternalMatch

Specified by:

getRule in interface Match

Returns:

The rule.

getConsequence

public Consequence getConsequence()

Specified by:
