Detailed Description

Definition of a base class for all instanciations of sequence.

The methods : Clear, Remove accepts a pointer to a function to use to delete the nodes. This allow proper call of the destructor on the Items. Without adding a virtual function pointer to each node or each sequence.

Constructor & Destructor Documentation

TCollection_BaseSequence::TCollection_BaseSequence ( )
protected

Creation of an empty sequence.

Member Function Documentation

void TCollection_BaseSequence::Clear ( const Standard_Address  DelNode)
protected
void TCollection_BaseSequence::Exchange ( const Standard_Integer  I,
const Standard_Integer  J 
)

Swaps elements which are located at positions and <J> in <me>. Raises an exception if I or J is out of bound. Example: before me = (A B C), I = 1, J = 3 after me = (C B A)

Standard_Address TCollection_BaseSequence::Find ( const Standard_Integer  Index) const
protected

Returns the node at position <index>.

Standard_Boolean TCollection_BaseSequence::IsEmpty ( ) const

returns True if the sequence <me> contains no elements.

Standard_Integer TCollection_BaseSequence::Length ( ) const

Returns the number of element(s) in the sequence. Returns zero if the sequence is empty.

void TCollection_BaseSequence::PAppend ( const Standard_Address  Node)
protected
void TCollection_BaseSequence::PAppend ( TCollection_BaseSequence S)
protected

Concatenates <S> at the end of <me>. <S> is cleared. Example: before me = (A B C) S = (D E F) after me = (A B C D E F) S = ()

void TCollection_BaseSequence::PInsertAfter ( const Standard_Integer  Index,
const Standard_Address  Node 
)
protected
void TCollection_BaseSequence::PInsertAfter ( const Standard_Integer  Index,
TCollection_BaseSequence S 
)
protected

Inserts the sequence <S> in <me> after the position <Index>. <S> is cleared. Raises an exception if the index is out of bound. Example: before me = (A B C), Index = 3, S = (D E F) after me = (A B C D E F) S = ()

void TCollection_BaseSequence::PPrepend ( const Standard_Address  Node)
protected
void TCollection_BaseSequence::PPrepend ( TCollection_BaseSequence S)
protected

Concatenates <S> at the beginning of <me>. <S> is cleared. Example: before me = (A B C) S = (D E F) after me = (D E F A B C) S = ()

void TCollection_BaseSequence::PSplit ( const Standard_Integer  Index,
TCollection_BaseSequence Sub 
)
protected

Keeps in <me> the items 1 to <Index>-1 and puts in the items <Index> to the end. Example: before me = (A B C D) ,Index = 3 after me = (A B) Sub = (C D)

void TCollection_BaseSequence::Remove ( const Standard_Integer  Index,
const Standard_Address  DelNode 
)
protected
void TCollection_BaseSequence::Remove ( const Standard_Integer  FromIndex,
const Standard_Integer  ToIndex,

)
protected
void TCollection_BaseSequence::Reverse ( )

Reverses the order of items on <me>. Example: before me = (A B C) after me = (C B A)
