Detailed Description

template<typename BT>
class FrameCPP::Common::BaseMemoryBufferT< BT >

Buffer appropriate for caching frame data.

If the buffer is for input, then the buffer needs to be initialized with the contents. The initialization needs to be done as via the call to the str( ) method before the buffer is associated with an IFrameStream object.

Template Parameters
BTInternal storage type to hold the buffer contents.
char buf[256];
BaseMemoryBuffer imb( );
imb.pubsetbuf( &(buf[0], sizeof( buf ) );
IFrameStream ifs_mem( false, &imb );

Constructor & Destructor Documentation

◆ BaseMemoryBufferT() [1/3]

template<typename BT >
FrameCPP::Common::BaseMemoryBufferT< BT >::BaseMemoryBufferT

Default constructor.

Parameters
[in]SeedMethod use for input buffers to move data into the new instance.
[in]ParentAutoDeleteTrue if dynamic memory associated with the temporary buffer should be release once this object goes out of scope.
Returns
New class instance.

The default constructor will initialize all the parts used in the general case.

◆ ~BaseMemoryBufferT()

template<typename BT >
FrameCPP::Common::BaseMemoryBufferT< BT >::~BaseMemoryBufferT
virtual

Destructor.

Be careful to release all the resources that were created for this object.

◆ BaseMemoryBufferT() [2/3]

template<typename BT >
FrameCPP::Common::BaseMemoryBufferT< BT >::BaseMemoryBufferT ( )

Default constructor.

Parameters
[in]SeedMethod use for input buffers to move data into the new instance.
[in]ParentAutoDeleteTrue if dynamic memory associated with the temporary buffer should be release once this object goes out of scope.
Returns
New class instance.

◆ BaseMemoryBufferT() [3/3]

template<typename BT >
FrameCPP::Common::BaseMemoryBufferT< BT >::BaseMemoryBufferT ( )

Default constructor.

Parameters
[in]SeedMethod use for input buffers to move data into the new instance.
[in]ParentAutoDeleteTrue if dynamic memory associated with the temporary buffer should be release once this object goes out of scope.
Returns
New class instance.

Member Function Documentation

◆ BufferId() [1/2]

const std::string & FrameCPP::Common::FrameBufferInterface::BufferId ( ) const
inlineinherited

Retrieve the string identification of the buffer.

Returns
An identifier associated with the open buffer.

◆ BufferId() [2/2]

const std::string & FrameCPP::Common::FrameBufferInterface::BufferId ( ) const
inherited

Retrieve the string identification of the buffer.

Returns
An identifier associated with the open buffer.

◆ FilterAdd() [1/2]

void FrameCPP::Common::FrameBufferInterface::FilterAdd ( FrameCPP::Common::StreamFilter *  Filter)
virtualinherited

Adds a filter to the stream.

Parameters
[in]FilterFilter function to add to the stream

◆ FilterAdd() [2/2]

virtual void FrameCPP::Common::FrameBufferInterface::FilterAdd ( FrameCPP::Common::StreamFilter *  Filter)
virtualinherited

Adds a filter to the stream.

Parameters
[in]FilterFilter function to add to the stream

◆ FilterInternally()

template<typename BT >
bool FrameCPP::Common::BaseMemoryBufferT< BT >::FilterInternally

Returns true if filtering happens internally; false otherwise.

Filtering currently is not optimized at the this layer so this method will always return false.

◆ FilterRemove() [1/2]

void FrameCPP::Common::FrameBufferInterface::FilterRemove ( FrameCPP::Common::StreamFilter *  Filter)
virtualinherited

Removes a filter from the stream.

Parameters
[in]FilterFilter function to remove from the stream

◆ FilterRemove() [2/2]

virtual void FrameCPP::Common::FrameBufferInterface::FilterRemove ( FrameCPP::Common::StreamFilter *  Filter)
virtualinherited

Removes a filter from the stream.

Parameters
[in]FilterFilter function to remove from the stream
