oracle.jbo
Class ExprEval

java.lang.Object
oracle.jbo.ExprEval

All Implemented Interfaces:

java.io.Serializable, JIReservedVarNames, JboReservedVarNames

Direct Known Subclasses:

RowMatch

public class ExprEval

extends java.lang.Object

implements java.io.Serializable, JboReservedVarNames

Used to evaluate groovy expressions. (This class is also used internally by the framework to evaluate java and sql expressions, but they are not for use outside of the framework and are not for use directly by any application). Use eval = new ExprEval(String groovyScriptString, ExprEval.EXPR_STYLE_GROOVY) to create this evaluator and then invoke evaluate(ExprValueSupplier, Map) method by passing in the Object (instance of ExprValueSupplier) on which to run the expression on and a Map of top level custom names that you may want to interpret when the names are referred in the script.
