Member Function Documentation

AsString()

PString PASN_ObjectId::AsString

(

)

const

Clone()

virtual PObject* PASN_ObjectId::Clone ( ) const

virtual

Create a copy of the class on the heap.

The exact semantics of the descendent class determine what is required to make a duplicate of the instance. Not all classes can even do a clone operation.

The main user of the clone function is the PDictionary class as it requires copies of the dictionary keys.

The default behaviour is for this function to assert.

Returns

pointer to new copy of the class instance.

Reimplemented from PObject.

Reimplemented in PRFC1155_ObjectName.

CommonDecode()

PBoolean PASN_ObjectId::CommonDecode	(	PASN_Stream &	strm,
		unsigned	dataLen
	)

CommonEncode()

void PASN_ObjectId::CommonEncode

(

PBYTEArray &

eObjId

)

const

Compare()

virtual Comparison PASN_ObjectId::Compare ( const PObject &  obj ) const

virtual

Compare the two objects and return their relative rank.

This function is usually overridden by descendent classes to yield the ranking according to the semantics of the object.

The default function is to use the CompareObjectMemoryDirect() function to do a byte wise memory comparison of the two objects.

Returns

LessThan, EqualTo or GreaterThan according to the relative rank of the objects.

Reimplemented from PObject.

Decode()

virtual PBoolean PASN_ObjectId::Decode ( PASN_Stream &  )

virtual

Implements PASN_Object.

Encode()

virtual void PASN_ObjectId::Encode ( PASN_Stream &  ) const

virtual

Implements PASN_Object.

GetDataLength()

virtual PINDEX PASN_ObjectId::GetDataLength ( ) const

virtual

Implements PASN_Object.

GetSize()

PINDEX PASN_ObjectId::GetSize ( ) const

inline

GetTypeAsString()

virtual PString PASN_ObjectId::GetTypeAsString ( ) const

virtual

Return a string giving the type of the object.

Implements PASN_Object.

PrintOn()

virtual void PASN_ObjectId::PrintOn ( ostream &  strm ) const

virtual

Output the contents of the object to the stream.

The exact output is dependent on the exact semantics of the descendent class. This is primarily used by the standard operator<< function.

The default behaviour is to print the class name.

Reimplemented from PObject.
