oracle.jbo.common
Class DefaultExprDef

java.lang.Object
oracle.jbo.common.DefaultExprDef

All Implemented Interfaces:

ExprDef

public abstract class DefaultExprDef

extends java.lang.Object

implements ExprDef

An abstract implementation of an ExprDef. The DefaultExprDef adapts a general GroovyCodeSource for use with the ADF groovy compiler/evaluator. Libraries that do not define a proper ADF ExprDef implementation may create a DefaultExprDef to use the ADF groovy compiler/evaluate. The DefaultExprDef provides default implementations of many of the ADF ExprDef APIs that may not be appropriate for more general purpose groovy evaluation.

OwnerType	getOwnerType() Returns the type of object that owners the expression class.
ExprEval.TrustMode	getTrustMode() The trust mode for the expression.
ExprEval.TypeCheckedMode	getTypeCheckedMode() Returns whether the expresion should be type checked when type checking is enabled for the groovy compiler.
ExprDef.Visibility	getVisibility() The visibility of the expression.
boolean	hasReturn() If the expression has a return value.
