Class PartitionedJCacheStatistics.CacheStatisticsExtractor

    • Method Detail

      • extractFromEntry

        public Object extractFromEntry​(Map.Entry entry)
        Description copied from class: AbstractExtractor
        Extract the value from the passed Entry object. The returned value should follow the conventions outlined in the AbstractExtractor.extract(T) method. By overriding this method, an extractor implementation is able to extract a desired value using all available information on the corresponding Map.Entry object and is intended to be used in advanced custom scenarios, when application code needs to look at both key and value at the same time or can make some very specific assumptions regarding to the implementation details of the underlying Entry object.
        Overrides:
        extractFromEntry in class AbstractExtractor
        Parameters:
        entry - an Entry object to provide context to lookup up appropriate resource registry.
        Returns:
        JCache CacheStatistics looked up via entry's context.
      • readExternal

        public void readExternal​(DataInput in)
                          throws IOException
        Description copied from interface: ExternalizableLite
        Restore the contents of this object by loading the object's state from the passed DataInput object.
        Specified by:
        readExternal in interface ExternalizableLite
        Parameters:
        in - the DataInput stream to read data from in order to restore the state of this object
        Throws:
        IOException - if an I/O exception occurs
        NotActiveException - if the object is not in its initial state, and therefore cannot be deserialized into

        public void writeExternal​(DataOutput out)
                           throws IOException
        Description copied from interface: ExternalizableLite
        Save the contents of this object by storing the object's state into the passed DataOutput object.
        Specified by:
        writeExternal in interface ExternalizableLite
        Parameters:
        out - the DataOutput stream to write the state of this object to

        Specified by:
        readExternal in interface PortableObject
        Parameters:
        in - the PofReader from which to read the object's state
