User Level:Normal
Library:RavlIO
In Scope:RavlN

Parent Classes: Derived Classes: Methods:
DPOSPortC()
Default constructor.

DPOSPortC(const DPOSPortC<DataT> & oth)
Copy constructor.

DPOSPortC(const DPOPortBaseC & oth)
Base constructor.

const DPOSPortC<DataT> & operator =(const DPOSPortC<DataT> & obj)
Assigment.

#include "Ravl/DP/Port.hh"
bool Put(const DataT & dat)
Put data to stream
Returns true if data is put into stream succesfully.

IntT PutArray(const SArray1dC<DataT> & data)
Put an array of data elements into a stream.
returns the number of elements processed from the array.

bool IsPutReady() const
Is port ready for data ?

#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/Port.hh"
void PutEOS()
Put End Of Stream marker.

const type_info & OutputType() const
Get type of output port.

#include "Ravl/DP/Entity.hh"
const DPEntityC & operator =(const DPEntityC & dat)
Assignment.

DPEntityBodyC & Body()
Access body.

const DPEntityBodyC & Body() const
Access body.

#include "Ravl/DP/Port.hh"
bool IsAsync() const
Does port work asynchronously ??

DPPortC ConnectedTo() const
Is this port connected to another ?
If not returns invalid handle.

bool GetAttr(const StringC & attrName,StringC & attrValue)
Get a stream attribute.
Returns false if the attribute name is unknown. This is for handling stream attributes such as frame rate, and compression ratios.

StringC GetAttr(const StringC & attrName)
Get a stream attribute.
Return the value of an attribute or an empty string if its unkown. This is for handling stream attributes such as frame rate, and compression ratios.

bool SetAttr(const StringC & attrName,const StringC & attrValue)
Set a stream attribute.
Returns false if the attribute name is unknown. This is for handling stream attributes such as frame rate, and compression ratios.

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

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

RCAbstractC Abstract()
Create an abstract handle.

istream & operator >>(istream & strm,RCHandleVC<DPEntityBodyC> & obj)

BinIStreamC & operator >>(BinIStreamC & strm,RCHandleVC<DPEntityBodyC> & obj)

#include "Ravl/DP/Entity.hh"
const DPEntityC & operator =(const DPEntityC & dat)
Assignment.

DPEntityBodyC & Body()
Access body.

const DPEntityBodyC & Body() const
Access body.

#include "Ravl/RefCounter.hh"
const RCHandleC<DPEntityBodyC> & operator =(const RCHandleC<DPEntityBodyC> & oth)
Assign handle.

RCHandleC<DPEntityBodyC> DeepCopy(UIntT levels = ((UIntT))) const
Do a deep copy of the object.

bool operator ==(const RCHandleC<DPEntityBodyC> & oth) const
Are handles to the same object ?

bool operator !=(const RCHandleC<DPEntityBodyC> & oth) const
Are handles to different objects ?

UIntT Hash() const
Default hash function.
This hashes on the address of the body.

bool IsValid() const
Test if this is a valid handle.

void Invalidate()
Invalidate this handle.
Unattaches the body from the handle.

bool IsHandleType(const DT &) const
Is handle of given type ?

void CheckHandleType(const DT & dummy) const
Check handle type. Throw an expception if not.

UIntT References() const
Find the number of references to the body of this object.

ostream & operator <<(ostream & strm,const RCHandleC<DPEntityBodyC> & obj)

istream & operator >>(istream & strm,RCHandleC<DPEntityBodyC> & obj)
