Method Detail

qualifies

public abstract boolean qualifies(ProvAPIEvent event)

Returns true if the implementation has determined that this event satisfies the requirements to notify the associated listener.

Parameters:

event - the object representing the event has occurred.

Returns:

true if the implementation has determined that this event satisfies the requirements to notify the associated listener.

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
                         ClassNotFoundException

Externalizable interface. The object implements the readExternal method to restore its contents by calling the methods of DataInput for primitive types and readObject for objects, strings and arrays. The readExternal method must read the values in the same sequence and with the same types as were written by writeExternal.

Specified by:

readExternal in interface Externalizable

Parameters:

in - the stream to read data from in order to restore the object

Throws:

IOException - if I/O errors occur

ClassNotFoundException - If the class for an object being restored cannot be found.

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Externalizable interface. The object implements the writeExternal method to save its contents by calling the methods of DataOutput for its primitive values or calling the writeObject method of ObjectOutput for objects, strings, and arrays.

Specified by:

writeExternal in interface Externalizable

Parameters:

out - the stream to write the object to

Throws:

IOException - Includes any I/O exceptions that may occur
