Detailed Description

Class for ASN Array type.

Constructor & Destructor Documentation

PASN_Array::PASN_Array ( unsigned  tag = UniversalSequence,
TagClass  tagClass = UniversalTagClass 
)
protected
PASN_Array::PASN_Array ( const PASN_Array other)
protected

Member Function Documentation

void PASN_Array::Append ( PASN_Object obj)
inline
virtual Comparison PASN_Array::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 PASN_Object* PASN_Array::CreateObject ( ) const
pure virtual

Implemented in PSNMP_VarBindList.

virtual PBoolean PASN_Array::Decode ( PASN_Stream )
virtual

Implements PASN_Object.

virtual void PASN_Array::Encode ( PASN_Stream ) const
virtual

Implements PASN_Object.

virtual PINDEX PASN_Array::GetDataLength ( ) const
virtual

Implements PASN_Object.

PINDEX PASN_Array::GetSize ( ) const
inline
virtual PString PASN_Array::GetTypeAsString ( ) const
virtual

Return a string giving the type of the object.

Implements PASN_Object.

virtual PBoolean PASN_Array::IsPrimitive ( ) const
virtual

Reimplemented from PASN_Object.

PASN_Array& PASN_Array::operator= ( const PASN_Array other)
PASN_Object& PASN_Array::operator[] ( PINDEX  i) const
inline
virtual void PASN_Array::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_Array::RemoveAt ( PINDEX  i)
inline
virtual void PASN_Array::SetConstraintBounds ( ConstraintType  type,
int  lower,
unsigned  upper 
)
virtual

Reimplemented from PASN_ConstrainedObject.

PBoolean PASN_Array::SetSize ( PINDEX  newSize)
