All Implemented Interfaces:

Serializable, PortableObject

public class BRLRuleModel
extends RuleModel

A RuleModel that can provide details of bound Facts and Fields from an associated Decision Table. This allows columns using BRL fragments to integrate with Decision Table columns

Method Detail

getLHSBoundFacts

public List<String> getLHSBoundFacts()

Description copied from class: RuleModel

This will return a List of all FactPattern bindings

Overrides:

getLHSBoundFacts in class RuleModel

Returns:

The bindings or an empty list if no bindings are found.

getLHSBoundFact

public FactPattern getLHSBoundFact(String var)

Description copied from class: RuleModel

This will return the FactPattern that a variable is bound Eto.

Overrides:

getLHSBoundFact in class RuleModel

Parameters:

var - The bound fact variable (NOT bound field).

Returns:

null or the FactPattern found.

getLHSBoundField

public FieldConstraint getLHSBoundField(String var)

Description copied from class: RuleModel

This will return the FieldConstraint that a variable is bound to.

Overrides:

getLHSBoundField in class RuleModel

Parameters:

var - The bound field variable (NOT bound fact).

Returns:

null or the FieldConstraint found.

getLHSBindingType

public String getLHSBindingType(String var)

Description copied from class: RuleModel

Get the data-type associated with the binding

Overrides:

getLHSBindingType in class RuleModel

Returns:

The data-type, or null if the binding could not be found

getLHSParentFactPatternForBinding

public FactPattern getLHSParentFactPatternForBinding(String var)

Description copied from class: RuleModel

This will return the FactPattern that a variable is bound to. If the variable is bound to a FieldConstraint the parent FactPattern will be returned.

Overrides:

getLHSParentFactPatternForBinding in class RuleModel

Parameters:

var - The variable binding

Returns:

null or the FactPattern found.

getAllVariables

public List<String> getAllVariables()

Description copied from class: RuleModel

This will get a list of all bound variables (LHS and RHS), including bound fields..

Overrides:

getAllVariables in class RuleModel

getAllLHSVariables

public List<String> getAllLHSVariables()

Description copied from class: RuleModel

This will get a list of all LHS bound variables, including bound fields..

Overrides:

getAllLHSVariables in class RuleModel

getAllRHSVariables

public List<String> getAllRHSVariables()

Description copied from class: RuleModel

This will get a list of all RHS bound variables.

Overrides:

getAllRHSVariables in class RuleModel

isBoundFactUsed

public boolean isBoundFactUsed(String binding)

Overrides:

isBoundFactUsed in class RuleModel

Parameters:

binding - The name of the LHS fact binding.

Returns:

Returns true if the specified binding is used on the RHS.

getBoundVariablesInScope

public List<String> getBoundVariablesInScope(BaseSingleFieldConstraint con)

Overrides:

getBoundVariablesInScope in class RuleModel

isVariableNameUsed

public boolean isVariableNameUsed(String s)

Description copied from class: RuleModel

Checks to see if a variable is used or not, includes fields as well as facts.

Overrides:

isVariableNameUsed in class RuleModel

getRHSBoundFacts

public List<String> getRHSBoundFacts()

Description copied from class: RuleModel

This will return a List of all ActionInsertFact bindings

Returns:

The bindings or an empty list if no bindings are found.

getRHSBoundFact

public ActionInsertFact getRHSBoundFact(String var)

Description copied from class: RuleModel

This will return the ActionInsertFact that a variable is bound to.
