DPIPortC port;

DPISPortAttachBodyC()

Default constructor.

DPISPortAttachBodyC(const DPIPortC<DataT> & aport,const DPSeekCtrlC & sc)

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

DPISPortAttachBodyC(const DPIPortC<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

bool IsGetReady() const

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

bool IsGetEOS() const

Has the End Of Stream been reached ?
true = yes.

const type_info & InputType() const

Input type.

DataT Get()

Get next piece of data.

bool Get(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.

DataT Get()

Get next piece of data.
May block if not ready, or it could throw an DataNotReadyC exception. NB. This function MUST be provided by client class.

bool Get(DataT & buff)

Try and get next piece of data.
This may not NOT block, if no data is ready it will return false, and not set buff. NB. The default version of this function uses the Get() method defined above and so need not be provided by derived classes.

IntT GetArray(SArray1dC<DataT> & data)

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

const type_info & InputType() const

Input type.

bool Save(ostream & out) const

Save to ostream.

bool Discard()

Discard the next input datum.

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

bool IsGetReady() const

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

bool IsGetEOS() const

Save to ostream.

DPPortC ConnectedTo() const

Is this port connected to another ?
If not returns invalid handle.

bool GetAttr(const StringC & attrName,StringC & attrValue)

Returns false if the attribute name is unknown. This is for handling stream attributes such as frame rate, and compression ratios.

bool SetAttr(const StringC & attrName,const StringC & attrValue)
