public DPOSPortBodyC<DataT>
public DPSeekCtrlAttachBodyC

DPOSPortAttachBodyC()

Default constructor.

DPOSPortAttachBodyC(const DPOPortC<DataT> & aport,const DPSeekCtrlC & sc)

Constructor.
Attach 'aport' to seek ctrl 'sc'

DPOSPortAttachBodyC(const DPOPortC<DataT> & aport,bool smartDefault = true)

Constructor.
Attach 'aport' to seek ctrl 'sc'

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 PutEOS()

Is some data ready ?
true = yes. Defaults to !IsGetEOS().

const type_info & OutputType() const

Input type.

bool Put(const DataT & buff)

Try and get next piece of data.

DPPortC ConnectedTo() const

What does this connect to ?

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.

bool Put(const DataT &)

Put data.
This function MUST be provided by client class.

IntT PutArray(const SArray1dC<DataT> & data)

Put an array of data to stream.
returns number of elements processed. NB. This need NOT be overridden in client classes unless fast handling of arrays of data elements is required.

const type_info & OutputType() const

Input type.

bool Save(ostream & out) const

Save to ostream.

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

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

void PutEOS()
