Member Function Documentation

virtual PObject* PASN_Sequence::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 PASN_Set.

virtual Comparison PASN_Sequence::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_Sequence::Decode ( PASN_Stream & ) [virtual]

Implements PASN_Object.

virtual void PASN_Sequence::Encode ( PASN_Stream & ) const [virtual]

Implements PASN_Object.

virtual PINDEX PASN_Sequence::GetDataLength ( ) const [virtual]

Implements PASN_Object.

PINDEX PASN_Sequence::GetSize ( ) const [inline]

virtual PString PASN_Sequence::GetTypeAsString ( ) const [virtual]

Return a string giving the type of the object

Implements PASN_Object.

Reimplemented in PASN_Set.

PBoolean PASN_Sequence::HasOptionalField ( PINDEX opt ) const

void PASN_Sequence::IncludeOptionalField ( PINDEX opt )

virtual PBoolean PASN_Sequence::IsPrimitive ( ) const [virtual]

Reimplemented from PASN_Object.

void PASN_Sequence::PreambleEncodePER ( PPER_Stream & strm ) const

virtual void PASN_Sequence::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.
