Detailed Description

DtObjectId instances are used to represent RTI::ObjectInstances in VR-Link.

In HLA 13 DtObjects represent RTI::ObjectInstances. It is possible that an instance of a DtObject could be a placeholder for VR-Link and not correspond to an object in the RTI. In HLA 1516 DtObjects can be real objects, invalid objects, or invalid objects which are placeholders. The difference between invalid objects, and invalid objects which are placeholders is that the string() which is used to generate a hash key, will be the same for plane invalid objects, but for invalid objects which are placeholders, the string will be unique.

Constructor & Destructor Documentation

DtObjectId::DtObjectId

(

)

The Default constructor.

In 1516 this creates an invalid DtObject. When a DtObject is created using this default constructor it will have an invalid ID of 1.

DtObjectId::DtObjectId

(

RTI::ObjectHandle

id

)

DtObjectId::DtObjectId

(

const char *

str

)

This constructor from a string is not provided by the 1516 interface.

DtObjectId::DtObjectId

(

const DtNetObjectId &

netId

)

This constructor from an integer is not allowed in 1516.

DtObjectId::DtObjectId

(

const DtObjectId &

orig

)

Member Function Documentation

static const DtObjectId& DtObjectId::defaultId ( )

virtual int DtObjectId::invalidId ( ) const

virtual

returns 0, if the object is valid, 1, if the object is invalid and not unique >1, if the object is unique (created as a placeholder)

virtual void DtObjectId::makePlaceholder ( )

virtual

makePlaceholder() causes this object, if it is invalid, to have a unique DtObjectId Hash Key, by setting the invalid ID to a unique number.
