 Returns a description of why the match has failed.
 
bool canOperatePerBlock () const override
 Tells the host if it can operate on a block-by-block basis.
 
void prepare (double, size_t, size_t, size_t) override
 Prepare for processing It is guaranteed that all subsequent process() calls will be in line with the arguments received in this callback. This callback is guaranteed to be called after canOperatePerBlock() If any of the values supplied by this callback are not supported by the matcher, it is expected to act as if the match has failed when match() gets called.

Detailed Description

template<typename SampleType>
class hart::NoDenormals< SampleType >

Checks whether the audio has no denormal values.

This matcher scans the audio signal for denormal (subnormal) floating-point values.

Definition at line 17 of file hart_no_denormals.hpp.

Member Function Documentation

◆ match()

template<typename SampleType >
bool match ( AnalysisContext< SampleType >  analysisContext)
inlineoverridevirtual

Tells the host if the piece of audio satisfies Matcher's condition or not.

It is guaranteed to be called only after prepare(), or not be called at all. It is guaranteed to be handed a pair of AudioBuffers in line with values set by the last prepare() call. If canOperatePerBlock() has returned false, this callback is guaranteed to be handed a full piece of audio to check. Otherwise, it may still get a full piece of audio, or get data on a block-by-block basis.

Parameters
analysisContextCarries everything matcher should know about the input and output audio.
Returns
true if the audio satisfies the Matcher's condition, false otherwise

Reimplemented from MatcherBase< SampleType >.

Definition at line 21 of file hart_no_denormals.hpp.

◆ getFailureDetails()

template<typename SampleType >
MatcherFailureDetails getFailureDetails ( ) const
inlineoverridevirtual

Returns a description of why the match has failed.

It is guaranteed to be called strictly after calling match(), or not called at all

Note
This method is a callback for the test host, so you probably don't need to call it yourself ever. If you're making a custom matcher, use it to communicate the data with test host.
Return values
MatcherFailureDetails::frameIndex of frame at which the match has failed
MatcherFailureDetails::channelIndex of channel at which the failure was detected
MatcherFailureDetails::descriptionReadable description of why the match has failed. Do not include the value of observed frame value or its timing in the description, as well as any of values printed by represent(), as all of this will be added to the output anyway. Also, query hart::CLIConfig for number of displayed decimal places, whenever applicable.

◆ canOperatePerBlock()

template<typename SampleType >
bool canOperatePerBlock ( ) const
inlineoverridevirtual

Tells the host if it can operate on a block-by-block basis.

Some types of conditions absolutely require having a full piece of audio to produce an appropriate response. For example, hart::PeaksAt matcher. Those types of matchers will return false on this callback. Matcher is guaranteed to receive a full piece of audio if this callback has returned false. Otherwise, it may receive audio either block-by-block basis, or still get a full piece of audio, if the host decides to do so.

Implements MatcherBase< SampleType >.

Definition at line 65 of file hart_no_denormals.hpp.

◆ prepare()

template<typename SampleType >
void prepare ( double  sampleRateHz,
size_t  numInputChannels,
size_t  numOutputChannels,
size_t  maxBlockSizeFrames 
)
inlineoverridevirtual

Prepare for processing It is guaranteed that all subsequent process() calls will be in line with the arguments received in this callback. This callback is guaranteed to be called after canOperatePerBlock() If any of the values supplied by this callback are not supported by the matcher, it is expected to act as if the match has failed when match() gets called.

Parameters
sampleRateHzsample rate at which the audio should be interpreted
numInputChannelsNumber of channels in the input (reference) audio
numOutputChannelsNumber of channels in the output (observed) audio
maxBlockSizeFramesMaximum block size in frames (samples)
