Detailed Description

A class that wraps a set of series-connected sound filters.

This class is a convenience class that allows the user to quickly connect a series of sound filters. This class is analogous to a 'channel strip' in most digital audio workstations.

Note that this class does not own any of the filters that it connects. It merely provides an easy way to process them in series. One should store the filter objects at some other location and pass pointers to this class. The behavior is undefined if any filter is destroyed while a filter series still has a reference to it.

For filters that have multiple inputs or outputs, the filter series uses a 1 to 1 matching for filter inputs/outputs. For instance, if a 2 output filter is followed by a 4-input filter, the two outputs of the first filter are sent to the first two inputs of the second filter. Any non-overlapping inputs or outputs are simply ignored. Use FilterGraph instead if you need complex routing capabilities.

Constructor & Destructor Documentation

om::sound::filters::FilterSeries::FilterSeries ( )

Create a default sound filter series with no connected sound filters.

Member Function Documentation

Size om::sound::filters::FilterSeries::getFilterCount ( ) const
inline

Return the total number of sound filters that are a part of this filter series.

SoundFilter* om::sound::filters::FilterSeries::getFilter ( Index  filterIndex)

Return a pointer to the sound filter at the specified index within this filter series.

If the specified filter index is not valid, NULL is returned.

Bool om::sound::filters::FilterSeries::setFilter ( Index  filterIndex,
SoundFilter newFilter 
)

Replace the filter in this filter series at the specified index.

If the specified filter index is invalid or the new filter pointer is NULL, FALSE is returned and the filter series is unchanged. Otherwise, the new filter replaces the old one and TRUE is returned.

Bool om::sound::filters::FilterSeries::addFilter ( SoundFilter newFilter)

Add a new filter to the end of this sound filter series.

If the new filter pointer is NULL, the method fails and returns FALSE. Otherwise, the method adds the new filter to the end of the filter series and returns TRUE.

Bool om::sound::filters::FilterSeries::insertFilter ( Index  filterIndex,
SoundFilter newFilter 
)

Insert the specified filter at the given index in this filter series.

If the new filter pointer is NULL, the method fails and returns FALSE. Otherwise, the filter is inserted in the filter series at the specified index and TRUE is returned.

Bool om::sound::filters::FilterSeries::removeFilter ( Index  filterIndex)

Remove the filter at the specified index from this filter series.

If the specified index is invalid, the method doesn't modify the filter series and returns FALSE. Otherwise, the filter at that index is removed and TRUE is returned.

Removing a filter at any given index causes the index of all filters with larger indices to be shifted back an index.

void om::sound::filters::FilterSeries::clearFilters ( )

Remove all filters from this sound filter series.

virtual UTF8String om::sound::filters::FilterSeries::getInputName ( Index  inputIndex) const
virtual

Return a human-readable name of the sound filter series input at the specified index.

This method returns the name of the input at the specified index in the first filter in the series.

Reimplemented from om::sound::filters::SoundFilter.

virtual UTF8String om::sound::filters::FilterSeries::getOutputName ( Index  outputIndex) const
virtual

Return a human-readable name of the sound filter series output at the specified index.

This method returns the name of the output at the specified index in the last filter in the series.

Reimplemented from om::sound::filters::SoundFilter.

virtual UTF8String om::sound::filters::FilterSeries::getName ( ) const
virtual

Return a human-readable name for this sound filter series.

The method returns the string "Sound Filter Series".

Reimplemented from om::sound::filters::SoundFilter.

virtual UTF8String om::sound::filters::FilterSeries::getManufacturer ( ) const
virtual

Return the manufacturer name of this sound filter series.

The method returns the string "Om Sound".

Reimplemented from om::sound::filters::SoundFilter.

virtual FilterVersion om::sound::filters::FilterSeries::getVersion ( ) const
virtual

Return an object representing the version of this sound filter series.

Reimplemented from om::sound::filters::SoundFilter.

virtual FilterCategory om::sound::filters::FilterSeries::getCategory ( ) const
virtual

Return an object that describes the category of effect that this filter implements.

This method returns the value FilterCategory::ROUTING.

Reimplemented from om::sound::filters::SoundFilter.
