public class PrefixAwareRecursionInterceptor extends Object implements RecursionInterceptor
RecursionInterceptor implementation that provides support for expressions
 with multiple synonyms, such as project.build.directory == pom.build.directory ==
 build.directory in Maven's POM.| Modifier and Type | Field and Description |

| Constructor and Description |

| PrefixAwareRecursionInterceptor(Collection<String> possiblePrefixes)Use the specified expression prefixes to detect synonyms. | 
| PrefixAwareRecursionInterceptor(Collection<String> possiblePrefixes,
                               boolean watchUnprefixedExpressions)Use the specified expression prefixes to detect synonyms, and specify whether
 unprefixed expressions can be considered synonyms. | 
| Modifier and Type | Method and Description | 
|---|---|
| void | clear()Reset the interceptor | 
| void | expressionResolutionFinished(String expression)Signal to the interceptor that the all efforts to resolve the given
 expression have completed - whether successfully or not is irrelevant -
 and that the expression should not be tracked for recursion any longer. | 
| void | expressionResolutionStarted(String expression)Log the intention to start resolving the given expression. | 
| List | getExpressionCycle(String expression)When an expression is determined to be a recursive reference, this method
 returns the sublist of tracked expressions that participate in this cycle. | 
| boolean | hasRecursiveExpression(String expression)Check whether the given value contains an expression that is currently
 being tracked by this interceptor. |
