If none, return false. else put data into buff.

IntT GetArray(SArray1dC<DataT> & data)

Get an array of data from stream.
returns the number of elements processed.

DPSeekCtrlBodyC & Body()

Access body class.

const DPSeekCtrlBodyC & Body() const

Access body class.

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

DPSeekCtrlBodyC & Body()

Access body class.

const DPSeekCtrlBodyC & Body() const

Access body class.

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
