Detailed Description

A class to contain all the global configuration options for FFTW.

A simple global lock is included that must be called before calling FFTW unsafe functions. It also handle cleanly the initialization and cleanup of FFTW.

This implementation was taken from the Insight Journal paper: http://hdl.handle.net/10380/3154 or http://insight-journal.com/browse/publication/717

Member Function Documentation

virtual ::itk::LightObject::Pointer itk::FFTWGlobalConfiguration::CreateAnother ( void ) const [private, virtual]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

static bool itk::FFTWGlobalConfiguration::ExportDefaultWisdomFileDouble ( ) [static]

Import or export some wisdom for the type double to/from the default file

static bool itk::FFTWGlobalConfiguration::ExportDefaultWisdomFileFloat ( ) [static]

Import or export some wisdom for the type float to/from the default file

static bool itk::FFTWGlobalConfiguration::ExportWisdomFileDouble ( const std::string & fname ) [static]

Import or export some wisdom for the type double to/from a file

static bool itk::FFTWGlobalConfiguration::ExportWisdomFileFloat ( const std::string & fname ) [static]

Import or export some wisdom for the type float to/from a file

static Pointer itk::FFTWGlobalConfiguration::GetInstance ( ) [static, private]

Return the singleton instance with no reference counting.

virtual const char* itk::FFTWGlobalConfiguration::GetNameOfClass ( ) const [virtual]

Run-time type information (and related methods).

Reimplemented from itk::Object.

static bool itk::FFTWGlobalConfiguration::GetNewWisdomAvailable ( ) [inline, static]

Set/Get wether a new wisdom is available compared to the initial state. If a new wisdom is available, the wisdoms may be written to the cache file

static std::string itk::FFTWGlobalConfiguration::GetPlanRigorName ( const int & value ) [static]

Translate plan rigor value to name. An exception is sent if the value is not valid.

static std::string itk::FFTWGlobalConfiguration::GetWisdomFileDefaultBaseName ( ) [static]

Returns:: Returns the full path for the file to be written if WriteWisdomCache is set to true. The file name is based on the naming strategy set in SetWisdomFilenameGenerator (defaults to HardwareWisdomFilenameGenerator). The file generated by GetWisdomFileDefaultBaseName() (with an "f" suffix for single precision wisdom files). The environmental variable ITK_FFTW_WISDOM_CACHE_BASE can be used to set the base directory name to place the file name specified by the GetWisdomFileDefaultBaseName(). The default location is the users home account directory.

static void itk::FFTWGlobalConfiguration::SetWisdomFilenameGenerator ( WisdomFilenameGeneratorBase * wfg ) [static]

allows application developers to create arbitrary rules for auto-generating cache file names. A default cache strategy is set to generate separate cache files for each unique operating system and hardware permutation. Alternate respresentative strategies are available to meet common use cases.
