Detailed Description

Workspace for real fast fourier transforms.

Constructor & Destructor Documentation

◆ workspace() [1/5]

gsl::fft::real::workspace::workspace ( )

inline

The default constructor is only really useful for assigning to.

Definition at line 278 of file fft_real.hpp.

References ccgsl_pointer, and count.

Referenced by operator=().

◆ workspace() [2/5]

gsl::fft::real::workspace::workspace ( size_t const n )

inlineexplicit

The default constructor creates a new workspace of size n.

Parameters

n	The size of the workspace.

Definition at line 288 of file fft_real.hpp.

References ccgsl_pointer, count, and gsl::rstat::n().

◆ workspace() [3/5]

gsl::fft::real::workspace::workspace ( gsl_fft_real_workspace * v )

inlineexplicit

Could construct from a gsl_fft_real_workspace.

This is not usually a good idea. In this case you should not use gsl_fft_real_workspace_free() to deallocate the memory.

Parameters

v	The workspace

Definition at line 304 of file fft_real.hpp.

References ccgsl_pointer, and count.

◆ workspace() [4/5]

gsl::fft::real::workspace::workspace ( workspace const & v )

inline

The copy constructor.

This creates a new reference to the workspace.

Parameters

v	The workspace to copy.

Definition at line 315 of file fft_real.hpp.

References ccgsl_pointer, and count.

◆ ~workspace()

gsl::fft::real::workspace::~workspace ( )

inline

The destructor only deletes the pointers if count reaches zero.

Definition at line 334 of file fft_real.hpp.

References ccgsl_pointer, and count.

◆ workspace() [5/5]

gsl::fft::real::workspace::workspace ( workspace && v )

inline

Move constructor.

Parameters

v	The workspace to move.

Definition at line 346 of file fft_real.hpp.

References count.

Member Function Documentation

◆ empty()

bool gsl::fft::real::workspace::empty ( ) const

inline

Find if the workspace is empty.

Returns: true if has size zero; otherwise false

Definition at line 423 of file fft_real.hpp.

References ccgsl_pointer.

◆ get()

gsl_fft_real_workspace * gsl::fft::real::workspace::get ( ) const

inline

Get the gsl_fft_real_workspace.

Returns: the gsl_fft_real_workspace

Definition at line 449 of file fft_real.hpp.

References ccgsl_pointer.

Referenced by gsl::fft::halfcomplex::backward(), gsl::fft::halfcomplex::inverse(), and gsl::fft::real::transform().

◆ operator bool()

gsl::fft::real::workspace::operator bool ( ) const

inlineexplicit

Allow conversion to bool.

Returns: true or false according as this contains a pointer to a gsl_fft_real_workspace

Definition at line 469 of file fft_real.hpp.

References ccgsl_pointer.

◆ operator!=()

bool gsl::fft::real::workspace::operator!= ( workspace const & v ) const

inline

Two workspace are different equal if their elements are not identical.

Parameters

v	The workspace to be compared with `this`

Returns: false or true according as this and v have identical elements or not

Definition at line 376 of file fft_real.hpp.

References operator==().

◆ operator<()

bool gsl::fft::real::workspace::operator< ( workspace const & v ) const

inline

A container needs to define an ordering for sorting.

This uses standard lexicographical ordering and so is not useful, for eaxmple, for checking, that a workspace is nonnegative.

Parameters

v	The workspace to be compared with `this`

Returns: false or true according as this is less than v lexicographically

Definition at line 388 of file fft_real.hpp.

References ccgsl_pointer.

◆ operator<=()

bool gsl::fft::real::workspace::operator<= ( workspace const & v ) const

inline

A container needs to define an ordering for sorting.

This uses standard lexicographical ordering and so is not useful, for eaxmple, for checking, that a workspace is nonnegative.

Parameters

v	The workspace to be compared with `this`

Returns: false or true according as this is less than or equal to v lexicographically

Definition at line 408 of file fft_real.hpp.

References ccgsl_pointer.

◆ operator=() [1/2]

workspace & gsl::fft::real::workspace::operator= ( workspace && v )

inline

Move operator.

Parameters

v	The workspace to move.

Returns: A reference to this.

Definition at line 355 of file fft_real.hpp.

References workspace().

◆ operator=() [2/2]

workspace & gsl::fft::real::workspace::operator= ( workspace const & v )

inline

The assignment operator.

This copies elementwise.

Parameters

v	The workspace to copy

Definition at line 322 of file fft_real.hpp.

References ccgsl_pointer, and count.

◆ operator==()

bool gsl::fft::real::workspace::operator== ( workspace const & v ) const

inline

Two workspace are identically equal if their elements are identical.

Parameters

v	The workspace to be compared with `this`

Returns: true or false according as this and v have identical elements or not

Definition at line 368 of file fft_real.hpp.

References ccgsl_pointer.

Referenced by operator!=().

◆ operator>()

bool gsl::fft::real::workspace::operator> ( workspace const & v ) const

inline

A container needs to define an ordering for sorting.

This uses standard lexicographical ordering and so is not useful, for eaxmple, for checking, that a workspace is nonnegative.

Parameters

v	The workspace to be compared with `this`

Returns: false or true according as this is greater than v lexicographically

Definition at line 398 of file fft_real.hpp.

References ccgsl_pointer.

◆ operator>=()

bool gsl::fft::real::workspace::operator>= ( workspace const & v ) const

inline

A container needs to define an ordering for sorting.

This uses standard lexicographical ordering and so is not useful, for eaxmple, for checking, that a workspace is nonnegative.

Parameters

v	The workspace to be compared with `this`

Returns: false or true according as this is no less than v lexicographically

Definition at line 418 of file fft_real.hpp.

References ccgsl_pointer.

◆ swap()

void gsl::fft::real::workspace::swap ( workspace & v )

inline

Swap two workspace.

This works even if the workspace have different sizes because it swaps pointers.

Parameters

v	The workspace to swap with `this`.

Definition at line 430 of file fft_real.hpp.

References ccgsl_pointer, and count.

◆ unique()

bool gsl::fft::real::workspace::unique ( ) const

inline

Find if this is the only object sharing the gsl_fft_real_workspace.

Returns: true or falses according as this is the only workspace object sharing the gsl_fft_real_workspace

Definition at line 455 of file fft_real.hpp.

References count.

◆ use_count()

size_t gsl::fft::real::workspace::use_count ( ) const

inline

Find how many workspace objects share this pointer.

Returns: the number of workspace objects that share this pointer

Definition at line 460 of file fft_real.hpp.

References count.
