Member Function Documentation

virtual PObject* PASN_Integer::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_Counter, PRFC1155_Gauge, and PRFC1155_TimeTicks.

virtual Comparison PASN_Integer::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.

virtual PBoolean PASN_Integer::Decode

(

PASN_Stream &

)

[virtual]

Implements PASN_Object.

(

PPER_Stream &

strm

)

virtual void PASN_Integer::Encode

(

PASN_Stream &

)

const [virtual]

Implements PASN_Object.

void PASN_Integer::EncodePER

(

PPER_Stream &

strm

)

const

virtual PINDEX PASN_Integer::GetDataLength

(

)

const [virtual]

Implements PASN_Object.

virtual PString PASN_Integer::GetTypeAsString

(

)

const [virtual]

Return a string giving the type of the object.

Implements PASN_Object.

PASN_Integer::operator unsigned

)

const [inline]

PASN_Integer& PASN_Integer::operator=

(

unsigned

value

)

Reimplemented in PRFC1155_Counter, PRFC1155_Gauge, and PRFC1155_TimeTicks.

virtual void PASN_Integer::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.

virtual void PASN_Integer::SetConstraintBounds	(	ConstraintType	type,
		int	lower,
		unsigned	upper
	)			[virtual]

Reimplemented from PASN_ConstrainedObject.
