Constructor Detail

ExceptionClassifierSkipPolicy

public ExceptionClassifierSkipPolicy()

Method Detail

setExceptionClassifier

public void setExceptionClassifier(SubclassClassifier<Throwable,SkipPolicy> classifier)

The classifier that will be used to choose a delegate policy.

Parameters:

classifier - the classifier to use to choose a delegate policy

setPolicyMap

public void setPolicyMap(Map<Class<? extends Throwable>,SkipPolicy> policyMap)

Setter for policy map. This property should not be changed dynamically - set it once, e.g. in configuration, and then don't change it during a running application. Either this property or the exception classifier directly should be set, but not both.

Parameters:

policyMap - a map of String to SkipPolicy that will be used to create a Classifier to locate a policy.

shouldSkip

public boolean shouldSkip(Throwable t,
                          int skipCount)
                   throws SkipLimitExceededException

Consult the classifier and find a delegate policy, and then use that to determine the outcome.

Specified by:

shouldSkip in interface SkipPolicy

Parameters:

t - the throwable to consider

skipCount - the current skip count

Returns:

true if the exception can be skipped

Throws:

SkipLimitExceededException - if a limit is exceeded
