public class SimpleRecursionInterceptor extends Object implements RecursionInterceptor
RecursionInterceptor, which checks whether
the existing interpolation effort is already attempting to resolve an exact
expression, but has not finished. This will not catch synonym expressions, as
are found in Maven (${project.build.directory}, ${pom.build.directory}, and
${build.directory} are synonyms).| Constructor and Description |

| Modifier and Type | Method and Description |
|---|---|
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 current expression is already present in the in-process
stack.
