Member Function Documentation

virtual PObject* PASN_Enumeration::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.

virtual Comparison PASN_Enumeration::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_Enumeration::Decode ( PASN_Stream & ) [virtual]

Implements PASN_Object.

PBoolean PASN_Enumeration::DecodePER ( PPER_Stream & strm )

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

Implements PASN_Object.

void PASN_Enumeration::EncodePER ( PPER_Stream & strm ) const

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

Implements PASN_Object.

unsigned PASN_Enumeration::GetMaximum ( ) const [inline]

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

Return a string giving the type of the object

Implements PASN_Object.

unsigned PASN_Enumeration::GetValue ( ) const [inline]

PINDEX PASN_Enumeration::GetValueByName ( PString name ) const

PASN_Enumeration::operator unsigned ( ) const [inline]

PASN_Enumeration& PASN_Enumeration::operator= ( unsigned v ) [inline]

virtual void PASN_Enumeration::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.

void PASN_Enumeration::SetValue ( unsigned v ) [inline]
