public class FzyPremise

extends FzyRuleComponent

implements XMLOutput, TextOutput

Method Detail

getAttributes

public java.util.Vector getAttributes()

Returns a Vector of all the attributes used in the premise of a rule. Recursivly searches through complex premises. The FzyAttributes returned are distinct - no duplicate values. Creation date: (1/12/00 1:48:47 PM)

Returns:

java.util.Vector

getAttributesForClause

private void getAttributesForClause(FzyClauseComponent comp,
                                    java.util.Vector v)

A recursive method that parses a premise for its FzyAttributes. Creation date: (1/11/00 1:44:43 PM)

Parameters:

comp - infosapient.system.FzyClauseComponent

v - java.util.Vector - used to hold the set of attributes.

getComponent

public FzyClauseComponent getComponent()

Return the clause component -- either a infosapient.parseObjects.ASTAttribClause or a infosapient.opr.FzyOperator.

Returns:

FzyClauseComponent

getName

public java.lang.String getName()

Overrides:

getName in class FzySystemComponent

reset

public void reset()

Description copied from class: FzyRuleComponent

Implemented by my subclasses to reinitialize themselves after a rule session has been performed by the rule engine.

Overrides:

reset in class FzyRuleComponent

setComponent

public void setComponent(FzyClauseComponent fcc)
                  throws java.lang.IllegalStateException,
                         java.lang.IllegalArgumentException

Add an ASTAttribClause to the Premise.

Parameters:

infosapient.parseObjects.ASTAttribClause - the clause component being added.

Throws:

java.lang.IllegalStateException - if attempt to add another attribute after first one added.

toXML

public java.lang.StringBuffer toXML(int nTabs)

Represent the rules premise as xml tags. Creation date: (1/30/00 9:13:18 PM)

Specified by:

toXML in interface XMLOutput

Returns:
