public class Event

extends ParamVector

Events are sent spontaneously from responders to initiators. Event codes, described in chapter 12 of the PTP specification, identify what happened. Some events have a parameter, and additional data (for vendor extensions) may be available using the class control request "Get Extended Event Data".

Method Summary

java.lang.String

getCodeName(int code) Subclasses override this to map PTP codes to their names; the results are always interned strings, so that they can be efficiently compared ("=", "!=") against constants.

getCodeName

public java.lang.String getCodeName(int code)

Description copied from class: Container

Subclasses override this to map PTP codes to their names; the results are always interned strings, so that they can be efficiently compared ("=", "!=") against constants. Such per-instance methods permit type-specific subclasses (and vendor extensions) to name their code values, invoking superclass methods to name all other codes.

Overrides:

getCodeName in class Container
