public class DevicePropValue

extends Data

DeviceProperty values wrap various types of integers and arrays of integers, and strings. It's sort of like a CORBA "Any", pairing a typecode and value, except that the typecode is known in advance so it's never marshaled.

Method Detail

getValue

getTypeCode

public int getTypeCode()

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 Data

getTypeName

public static java.lang.String getTypeName(int code)

Maps datatype codes to string names.

Parameters:

code - datatype code

Returns:

interned string identifying that datatype.
