Constructor Detail

PassThroughFilterAdapter

public PassThroughFilterAdapter()

Constructs a PassThroughFilterAdapter. (required for serialization)

PassThroughFilterAdapter

public PassThroughFilterAdapter(javax.cache.configuration.Factory<javax.cache.event.CacheEntryEventFilter<? super K,? super V>> factory)

Constructs a PassThroughFilterAdapter.

Parameters:

factory - a Factory to produce the CacheEntryEventFilter

Method Detail

evaluate

public boolean evaluate(Object object)

Description copied from interface: Filter

Apply the test to the input argument.

Specified by:

evaluate in interface Filter

Parameters:

object - the input argument to evaluate

Returns:

true if the input argument matches the filter, otherwise false

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

Throws:

IOException - if an I/O exception occurs

readExternal

public void readExternal(PofReader reader)
                  throws IOException

Description copied from interface: PortableObject

Restore the contents of a user type instance by reading its state using the specified PofReader object.

Specified by:

readExternal in interface PortableObject

Parameters:

reader - the PofReader from which to read the object's state

Throws:

IOException - if an I/O error occurs

writeExternal

public void writeExternal(PofWriter writer)
                   throws IOException

Description copied from interface: PortableObject

Save the contents of a POF user type instance by writing its state using the specified PofWriter object.

Specified by:

writeExternal in interface PortableObject

Parameters:

writer - the PofWriter to which to write the object's state

Throws:

IOException - if an I/O error occurs

getCacheEntryEventFilter

protected javax.cache.event.CacheEntryEventFilter<? super K,? super V> getCacheEntryEventFilter()

Obtains the CacheEntryEventFilter to which to delegate CacheEntryEvents.

Returns:

the CacheEntryEventFilter (or null if unavailable
