| constructor | |
| FilterBankEvent (const FilterBankEvent &fbk) | |
| copy constructor (shallow copy -- the generator shouldn't be going anywhere) | |
| const FilterBankEvent & | operator= (const FilterBankEvent &fbk) |
| assignment operator (shallow copy -- the generator shouldn't be going anywhere) | |
| virtual EventBase * | clone () const |
| allows a copy to be made of an event, supporting polymorphism | |
| FilterBankGenerator * | getSource () const |
| Gives access to underlying generator. | |
| unsigned int | getNumLayers () const |
| returns the number of image layers (e.g. different resolutions available) | |
| unsigned int | getNumChannels () const |
| returns the number of channels per image (e.g. Y, U, or V components) | |
| unsigned char * | getImage (unsigned int layer, unsigned int channel) const |
| returns pointer to the beginning of the image data for the specified layer and channel | |
| unsigned int | getWidth (unsigned int layer) const |
| returns width of the image in a given layer | |
| unsigned int | getHeight (unsigned int layer) const |
| returns height of the image in a given layer | |
| unsigned int | getSkip (unsigned int layer) const |
| returns the bytes to skip from the one-past-end of a row to get the beginning of the next | |
| unsigned int | getStride (unsigned int layer) const |
| returns the bytes to skip from the beginning of one row to get the beginning of the next | |
| unsigned int | getIncrement (unsigned int layer) const |
| returns the increment to use to go from one sample to the next | |
| unsigned int | getFrameNumber () const |
| returns the frame number, see FilterBankGenerator::frameNumber | |
| unsigned int | getFramesProcessed () const |
| returns the number of frames processed by the generator, see FilterBankGenerator::framesProcessed | |

Member Function Documentation
| virtual EventBase* FilterBankEvent::clone | ( | ) | const [inline, virtual] |
allows a copy to be made of an event, supporting polymorphism
Must be overridden by all subclasses to allow this to happen
I would like to switch this over to the cloneable interface once the compiler gets updated out of the 3.3 branch... see Cloneable::clone() for a discussion of the issue and implementation notes.
Reimplemented from EventBase.
Reimplemented in SegmentedColorFilterBankEvent.

| unsigned char* FilterBankEvent::getImage | ( | unsigned int | layer, | |
| unsigned int | channel | |||
| ) | const [inline] |
returns pointer to the beginning of the image data for the specified layer and channel
this will cause the data to be calculated and cached if it's not already available

Referenced by BallDetectionGenerator::processEvent().
| unsigned int FilterBankEvent::getStride | ( | unsigned int | layer | ) | const [inline] |
returns the bytes to skip from the beginning of one row to get the beginning of the next
This is just for convenience; the stride is just the skip plus the width, but it's precomputed for you for speed and clarity
