Method Detail

computeValue back to summary

protected PersistenceUtilHelper.ClassMetadataCache computeValue(final Class<T> type)

Implements abstract java.lang.ClassValue.computeValue.

Doc from java.lang.ClassValue.computeValue.

Computes the given class's derived value for this ClassValue.

This method will be invoked within the first thread that accesses the value with the get method.

Normally, this method is invoked at most once per class, but it may be invoked again if there has been a call to remove.

If this method throws an exception, the corresponding call to get will terminate abnormally with that exception, and no class value will be recorded.

Parameters

type:Class<T>: the type whose class value must be computed

Returns:PersistenceUtilHelper.ClassMetadataCache

the newly computed value associated with this ClassValue, for the given class or interface
