◆ getImpl()

ob_filter * ob::Filter::getImpl ( ) const

inline

Get the Impl object of the filter.

Returns: ob_filter* The Impl object of the filter.

Definition at line 129 of file Filter.hpp.

◆ getName()

virtual const std::string & ob::Filter::getName ( ) const

inlinevirtual

Get the type of filter.

Returns: string The type of filte.

Definition at line 138 of file Filter.hpp.

Referenced by type().

◆ reset()

virtual void ob::Filter::reset ( ) const

inlinevirtual

Reset the filter, freeing the internal cache, stopping the processing thread, and clearing the pending buffer frame when asynchronous processing is used.

Definition at line 146 of file Filter.hpp.

◆ enable()

virtual void ob::Filter::enable ( bool enable ) const

inlinevirtual

enable the filter

Definition at line 155 of file Filter.hpp.

Referenced by enable(), and isEnabled().

◆ isEnabled()

virtual bool ob::Filter::isEnabled ( ) const

inlinevirtual

Return Enable State.

Definition at line 164 of file Filter.hpp.

◆ process()

virtual std::shared_ptr< Frame > ob::Filter::process ( std::shared_ptr< const Frame > frame ) const

inlinevirtual

Processes a frame synchronously.

Parameters

frame The frame to be processed.

Returns: std::shared_ptr< Frame > The processed frame.

Definition at line 177 of file Filter.hpp.

◆ pushFrame()

virtual void ob::Filter::pushFrame ( std::shared_ptr< Frame > frame ) const

inlinevirtual

Pushes the pending frame into the cache for asynchronous processing.

Parameters

frame The pending frame. The processing result is returned by the callback function.

Definition at line 192 of file Filter.hpp.

◆ setCallBack()

virtual void ob::Filter::setCallBack ( FilterCallback callback )

inlinevirtual

Set the callback function for asynchronous processing.

Parameters

callback The processing result callback.

Definition at line 203 of file Filter.hpp.

◆ getConfigSchema()

virtual std::string ob::Filter::getConfigSchema ( ) const

inlinevirtual

Get config schema of the filter.

The returned string is a csv format string representing the configuration schema of the filter. The format of the string is: <parameter_name>, <parameter_type: "int", "float", "bool">, <minimum_value>, <maximum_value>, <value_step>, <default_value>, <parameter_description>

Returns: std::string The config schema of the filter.

Definition at line 217 of file Filter.hpp.

◆ getConfigSchemaVec()

virtual std::vector< OBFilterConfigSchemaItem > ob::Filter::getConfigSchemaVec ( ) const

inlinevirtual

Get the Config Schema Vec object.

The returned vector contains the config schema items. Each item in the vector is an OBFilterConfigSchemaItem object.

Returns: std::vector<OBFilterConfigSchemaItem> The vector of the filter config schema.

Definition at line 230 of file Filter.hpp.

◆ setConfigValue()

virtual void ob::Filter::setConfigValue	(	const std::string &	configName,
		double	value ) const

inlinevirtual

Set the filter config value by name.

Attention: The pass into value type is double, witch will be cast to the actual type inside the filter. The actual type can be queried by the filter config schema returned by getConfigSchemaVec.

Parameters

configName	The name of the config.
value	The value of the config.

◆ getConfigValue()

virtual double ob::Filter::getConfigValue ( const std::string & configName ) const

inlinevirtual

Get the Config Value object by name.

Attention: The returned value type has been casted to double inside the filter. The actual type can be queried by the filter config schema returned by getConfigSchemaVec.

Parameters

configName The name of the config.

Returns: double The value of the config.

Definition at line 258 of file Filter.hpp.

Check if the runtime type of the filter object is compatible with a given type.

Define the is() template function for the Filter class.

Template Parameters

T	The given type.

Returns: bool The result.
