public class RuleEvaluator
extends java.lang.Object

A nice tidy packaging of javax.el stuff.

Method Summary

Modifier and Type	Method	Description
static RuleEvaluator	createDefaultRuleEvaluator(java.util.Map<java.lang.String,java.lang.Object> testConstantsMap)
static LibraryFunctionMapperBuilder	defaultFunctionMapperBuilder()
boolean	evaluateBooleanRule(java.lang.String rule, java.util.Map<java.lang.String,java.lang.Object> values)	Deprecated. Use evaluateBooleanRuleWithValueExpr(String, Map) instead, it's more efficient
boolean	evaluateBooleanRuleWithValueExpr(java.lang.String rule, java.util.Map<java.lang.String,javax.el.ValueExpression> localContext)
java.lang.Object	evaluateRule(java.lang.String rule, java.util.Map<java.lang.String,java.lang.Object> values, java.lang.Class expectedType)	Deprecated. Use evaluateBooleanRule() instead, it checks against more errors

evaluateRule

@CheckForNull
@Deprecated
public java.lang.Object evaluateRule(java.lang.String rule,
                                     java.util.Map<java.lang.String,java.lang.Object> values,
                                     java.lang.Class expectedType)

Deprecated.

Use evaluateBooleanRule() instead, it checks against more errors

Parameters:

expectedType - class to coerce result to, use primitive instead of wrapper, e.g. boolean.class instead of Boolean.class.

Returns:

null or a Boolean value representing the expression evaluation result
