Methods:
DPSeekCtrlAttachBodyC(const DPSeekCtrlC & oth = DPSeekCtrlC ())
Constructor.

DPSeekCtrlAttachBodyC(const DPPortC & pb,bool smartDefault = true)
Constructor

bool Seek(UIntT off)
Seek to location in stream.

bool DSeek(IntT off)
Delta Seek, goto location relative to the current one.

UIntT Tell() const
Find current location in stream.

UIntT Size() const
Find the total size of the stream.

UIntT Start() const
Find the offset where the stream begins, normally zero.
Defaults to 0

void SetSeekCtrl(const DPSeekCtrlC & sc)
Set seek control.

#include "Ravl/DP/SPort.hh"
bool Seek(UIntT off)
Seek to location in stream.
Returns false, if seek failed. (Maybe because its not implemented.) if an error occurered (Seek returned False) then stream position will not be changed.

bool DSeek(IntT off)
Delta Seek, goto location relative to the current one.
The default behavour of this functions is : Do some error checking then: Seek((UIntT)((IntT) Tell() + off)); if an error occurered (DSeek returned False) then stream position will not be changed.

UIntT Tell() const
Find current location in stream.
Defined as the index of the next object to be written or read. May return ((UIntT) (-1)) if not implemented.

UIntT Size() const
Find the total size of the stream. (assuming it starts from 0)
May return ((UIntT) (-1)) if not implemented.

UIntT Start() const
Find the offset where the stream begins, normally zero.
Defaults to 0

#include "Ravl/DP/Entity.hh"
bool Save(ostream & out) const
Save to ostream.

bool Save(BinOStreamC & out) const
Save to binary stream.

RCBodyVC & Copy() const
Creat a copy of this object.

#include "Ravl/RCHandleV.hh"
bool Save(ostream & out) const
Save to stream 'out'.

bool Save(BinOStreamC & out) const
Save to binary stream 'out'.

RCBodyVC & Copy() const
Make copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

RCBodyC & DeepCopy(UIntT levels = ((UIntT))) const
Make a deep copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

#include "Ravl/RefCounter.hh"
UIntT References() const
Access count of handles open to this object.

RCBodyC & Copy() const
Make copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

RCBodyC & DeepCopy(UIntT levels = ((UIntT))) const
Make a deep copy of body.
This should be provided in derived classes. this funtion will issue an assertion failure if called.

void IncRefCounter()
Increment reference counter.

bool DecRefCounter()
Decrement reference counter.
