isAllowed

public boolean isAllowed(FactHandle handle,

Specified by:

isAllowed in interface AlphaNodeFieldConstraint

isUnification

public boolean isUnification()

Specified by:

isUnification in interface IndexableConstraint

public boolean isIndexable(int nodeType,
 KieBaseConfiguration config)

Specified by:

isIndexable in interface IndexableConstraint

getField

public FieldValue getField()

Specified by:

getLeftIndexExtractor

public Declaration getLeftIndexExtractor()

Specified by:

getLeftIndexExtractor in interface IndexableConstraint

getRequiredDeclarations

public Declaration[] getRequiredDeclarations()

Description copied from interface: Constraint

Returns all the declarations required by the given constraint implementation.

Specified by:

getRequiredDeclarations in interface Constraint

Returns:

replaceDeclaration

public void replaceDeclaration(Declaration oldDecl,
 Declaration newDecl)

Description copied from interface: Constraint

When a rule contains multiple logical branches, i.e., makes use of 'OR' CE, it is required to clone patterns and declarations for each logical branch. Since this is done at ReteOO build type, when constraints were already created, eventually some constraints need to update their references to the declarations.

Specified by:

replaceDeclaration in interface Constraint

clone

public Constraint clone()

Description copied from interface: Constraint

Clones the constraint

Specified by:

clone in interface Constraint

Overrides:

clone in class Object

Returns:

getQueryName

public String getQueryName()

getType

public Constraint.ConstraintType getType()

Description copied from interface: Constraint

Returns the type of the constraint, either ALPHA, BETA or UNKNOWN

Specified by:

getType in interface Constraint

Returns:

isTemporal

public boolean isTemporal()

Description copied from interface: Constraint

Returns true in case this constraint is a temporal constraint

Specified by:

isTemporal in interface Constraint

Returns:

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException
