Detailed Description

Type for GUID (Global Unique Identifier) representation.

Represents a 128 bit GUID.

Constructor & Destructor Documentation

GUID_t() [1/2]

GUID_t

(

GUID_t

guid

)

Copy constructor.

Parameters

guid	The GUID instance to copy. It must not be null.

References GUID_t.value.

GUID_t() [2/2]

GUID_t

(

byte[]

value

)

Constructor.

Parameters

value

GUID value as a 16 byte array. It must not be null.

References GUID_t.value.

Member Function Documentation

copy_from()

Object copy_from

(

Object

src

)

Copy value of a data type from source.

Copy data into this object from another. This copy is intended to be a deep copy, so that all data members (recursively) are copied (not just resetting Object references).

This operation returns the object that is copied if copy is successful.

Parameters

src	<<in>> The Object which contains the data to be copied.

Returns

Generally, return this but special cases (such as Enum) exist.

Exceptions

NullPointerException	If src is null.
ClassCastException	If src is not the same type as this.

Implements Copyable.

Member Data Documentation

GUID_UNKNOWN

final GUID_t GUID_UNKNOWN

static

Unknown GUID.

GUID_AUTO

final GUID_t GUID_AUTO

static

Initial value:

= 
        new GUID_t(new byte[]{0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0})

Indicates that RTI Connext should choose an appropriate virtual GUID.

If this special value is assigned to com.rti.dds.infrastructure.DataWriterProtocolQosPolicy.virtual_guid or com.rti.dds.infrastructure.DataReaderProtocolQosPolicy.virtual_guid, RTI Connext will assign the virtual GUID automatically based on the RTPS or physical GUID.

GUID_ZERO

final GUID_t GUID_ZERO

static

Zero GUID.

value

byte [] value = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0}

A 16 byte array containing the GUID value.
