public class Command

extends ParamVector

Command messages start PTP transactions, and are sent from initiator to responder. They include an operation code, either conform to chapter 10 of the PTP specification or are vendor-specific commands.

Create these objects in helper routines which package intelligence about a given Operation. That is, it'll know the command code, how many command and response parameters may be used, particularly significant response code, and whether the transaction has a data phase (and its direction).

Method Detail

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:
