Method Detail

evaluate

public java.util.concurrent.RunnableFuture<Result> evaluate(IItemCollection items,
                                                            IPreferenceValueProvider valueProvider)

Description copied from interface: IRule

Gets a future representing the result of the evaluation of this rule. Running the RunnableFuture is the responsibility of the caller of this method, not the implementation.

Specified by:

evaluate in interface IRule

Parameters:

items - items to evaluate

valueProvider - Provider of configuration values used for evaluation. The attributes that will be asked for from the provider should be provided by IRule.getConfigurationAttributes().

Returns:

a RunnableFuture that when run will return the evaluation result

getResult

private Result getResult(IItemCollection items,
                         IPreferenceValueProvider valueProvider)

hasSegmentedCodeCache

private boolean hasSegmentedCodeCache(IItemCollection items)

addIfHalfFull

private void addIfHalfFull(IQuantity ratioUnallocated,
                           java.util.List<CodeCacheRule.CodeHeapData> heaps,
                           java.lang.String name)
