Constructor & Destructor Documentation

◆ pdf() [1/5]

gsl::histogram2d::pdf::pdf ( )

inline

The default constructor is only really useful for assigning to.

Definition at line 631 of file histogram2d.hpp.

References ccgsl_pointer, and count.

Referenced by operator=().

◆ pdf() [2/5]

gsl::histogram2d::pdf::pdf	(	size_t const	nx,
		size_t const	ny
	)

inlineexplicit

The default constructor creates a new pdf with n elements.

Parameters

nx	The number of bin slices in x direction
ny	The number of bin slices in y direction

Definition at line 642 of file histogram2d.hpp.

References ccgsl_pointer, count, gsl::histogram2d::nx(), and gsl::histogram2d::ny().

◆ pdf() [3/5]

gsl::histogram2d::pdf::pdf ( gsl_histogram2d_pdf * v )

inlineexplicit

Could construct from a gsl_histogram2d_pdf.

This is not usually a good idea. In this case we should not use gsl_histogram2d_pdf_free() to deallocate the memory.

Parameters

v The pdf

Definition at line 658 of file histogram2d.hpp.

References ccgsl_pointer, and count.

◆ pdf() [4/5]

gsl::histogram2d::pdf::pdf ( pdf const & v )

inline

The copy constructor.

This creates a new reference to the workspace.

Parameters

v	The pdf to copy.

Definition at line 669 of file histogram2d.hpp.

References ccgsl_pointer, and count.

◆ ~pdf()

gsl::histogram2d::pdf::~pdf ( )

inline

The destructor only deletes the pointers if count reaches zero.

Definition at line 688 of file histogram2d.hpp.

References ccgsl_pointer, and count.

◆ pdf() [5/5]

gsl::histogram2d::pdf::pdf ( pdf && v )

inline

Move constructor.

Parameters

v	The pdf to move.

Definition at line 700 of file histogram2d.hpp.

References count.

Member Function Documentation

◆ empty()

bool gsl::histogram2d::pdf::empty ( ) const

inline

Find if the pdf is empty.

Returns: true if has size zero; otherwise false

Definition at line 777 of file histogram2d.hpp.

References ccgsl_pointer.

◆ get()

gsl_histogram2d_pdf * gsl::histogram2d::pdf::get ( ) const

inline

Get the gsl_histogram2d_pdf.

Returns: the gsl_histogram2d_pdf

Definition at line 803 of file histogram2d.hpp.

References ccgsl_pointer.

Referenced by init(), and sample().

◆ init()

int gsl::histogram2d::pdf::init ( histogram2d const & h ) const

inline

C++ version of gsl_histogram2d_pdf_init().

Parameters

h	A histogram2d

Returns: Error code on failure

Definition at line 830 of file histogram2d.hpp.

References gsl::histogram2d::get(), and get().

◆ operator bool()

gsl::histogram2d::pdf::operator bool ( ) const

inlineexplicit

Allow conversion to bool.

Returns: true or false according as this contains a pointer to a gsl_histogram2d_pdf.

Definition at line 823 of file histogram2d.hpp.

References ccgsl_pointer.

◆ operator!=()

bool gsl::histogram2d::pdf::operator!= ( pdf const & v ) const

inline

Two pdf are different if their elements are not identical.

Parameters

v	The pdf to be compared with `this`

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

Definition at line 730 of file histogram2d.hpp.

References operator==().

◆ operator<()

bool gsl::histogram2d::pdf::operator< ( pdf const & v ) const

inline

A container needs to define an ordering for sorting.

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

Parameters

v	The pdf to be compared with `this`

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

Definition at line 742 of file histogram2d.hpp.

References ccgsl_pointer.

◆ operator<=()

bool gsl::histogram2d::pdf::operator<= ( pdf const & v ) const

inline

A container needs to define an ordering for sorting.

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

Parameters

v	The pdf to be compared with `this`

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

Definition at line 762 of file histogram2d.hpp.

References ccgsl_pointer.

◆ operator=() [1/2]

pdf & gsl::histogram2d::pdf::operator= ( pdf && v )

inline

Move operator.

Parameters

v	The pdf to move.

Returns: A reference to this.

Definition at line 709 of file histogram2d.hpp.

References pdf().

◆ operator=() [2/2]

pdf & gsl::histogram2d::pdf::operator= ( pdf const & v )

inline

The assignment operator.

This copies elementwise.

Parameters

v	The pdf to copy

Definition at line 676 of file histogram2d.hpp.

References ccgsl_pointer, and count.

◆ operator==()

bool gsl::histogram2d::pdf::operator== ( pdf const & v ) const

inline

Two pdf are identically equal if their elements are identical.

Parameters

v	The pdf to be compared with `this`

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

Definition at line 722 of file histogram2d.hpp.

References ccgsl_pointer.

Referenced by operator!=().

◆ operator>()

bool gsl::histogram2d::pdf::operator> ( pdf const & v ) const

inline

A container needs to define an ordering for sorting.

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

Parameters

v	The pdf to be compared with `this`

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

Definition at line 752 of file histogram2d.hpp.

References ccgsl_pointer.

◆ operator>=()

bool gsl::histogram2d::pdf::operator>= ( pdf const & v ) const

inline

A container needs to define an ordering for sorting.

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

Parameters

v	The pdf to be compared with `this`

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

Definition at line 772 of file histogram2d.hpp.

References ccgsl_pointer.

◆ sample()

int gsl::histogram2d::pdf::sample	(	double	r1,
		double	r2,
		double &	x,
		double &	y
	)

inline

C++ version of gsl_histogram2d_pdf_sample().

Parameters

r1	A random number (between zero and 1)
r2	A random number (between zero and 1)
x	The x value (return value)
y	The y value (return value)

Returns: Error code on failure

Definition at line 853 of file histogram2d.hpp.

References get().

◆ swap()

void gsl::histogram2d::pdf::swap ( pdf & v )

inline

Swap two pdf objects.

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

Parameters

v	The pdf to swap with `this`.

Definition at line 784 of file histogram2d.hpp.

References ccgsl_pointer, and count.

◆ unique()

bool gsl::histogram2d::pdf::unique ( ) const

inline

Find if this is the only object sharing the gsl_histogram2d_pdf.

Returns: true or falses according as this is the only pdf object sharing the gsl_histogram2d_pdf.

Definition at line 809 of file histogram2d.hpp.

References count.

◆ use_count()

size_t gsl::histogram2d::pdf::use_count ( ) const

inline

Find how many pdf objects share this pointer.

Returns: the number of pdf objects that share this pointer.

Definition at line 814 of file histogram2d.hpp.

References count.
