Detailed Description

template<class IndexType>
struct GEO::basic_quadindex< IndexType >

A tuple of four indices.

Can be used as a key in associative data structures (std::map, std::set). The indices are defined by IndexType, generally signed or unsigned integers.

Template Parameters

IndexType

type of the indices

Definition at line 458 of file index.h.

Member Enumeration Documentation

KeepOrderType

template<class IndexType >

enum GEO::basic_quadindex::KeepOrderType

This type is used to overload basic_quadindex constructors with versions that keep the order of the stored indices.

Enumerator
KEEP_ORDER	Value to pass to basic_quadindex ordered constructor

Definition at line 469 of file index.h.

Constructor & Destructor Documentation

basic_quadindex() [1/3]

template<class IndexType >

GEO::basic_quadindex< IndexType >::basic_quadindex ( IndexType  i, IndexType  j, IndexType  k, IndexType  l  )

inline

Creates a basic_quadindex from four integers.

The integers are reordered.

Parameters

[in]	i	first integer
[in]	j	second integer
[in]	k	third integer
[in]	l	fourth integer

Definition at line 488 of file index.h.

basic_quadindex() [2/3]

template<class IndexType >

GEO::basic_quadindex< IndexType >::basic_quadindex ( IndexType  i, IndexType  j, IndexType  k, IndexType  l, KeepOrderType  order  )

inline

Creates a basic_quadindex from four integers and keeps their order.

The integers are not sorted.

Parameters

[in]	i	first integer
[in]	j	second integer
[in]	k	third integer
[in]	l	fourth integer
[in]	order	argument of type KeepOrderType used to select the right constructor. Use basic_quadindex::KEEP_ORDER for this argument.

Definition at line 513 of file index.h.

basic_quadindex() [3/3]

template<class IndexType >

GEO::basic_quadindex< IndexType >::basic_quadindex ( const basic_quadindex< IndexType > &  rhs )

default

Constructs a basic_quadindex from another one.

Parameters

[in]

rhs

the basic_quadindex this basic_quadindex should be copied from

Member Function Documentation

operator!=()

template<class IndexType >

bool GEO::basic_quadindex< IndexType >::operator!= ( const basic_quadindex< IndexType > &  rhs ) const

inline

Compares two basic_quadindex.

Parameters

[in]

rhs

the basic_quadindex to compare this basic_quadindex with.

Returns

true if one of the indices in rhs differs from the index in this basic_quadindex at the same position, false otherwise.

Definition at line 569 of file index.h.

operator<()

template<class IndexType >

bool GEO::basic_quadindex< IndexType >::operator< ( const basic_quadindex< IndexType > &  rhs ) const

inline

Compares two basic_quadindex.

Parameters

[in]

rhs

the basic_quadindex to compares this basic_quadindex with.

Returns

true if rhs is smaller than this basic_quadindex according to the lexicographic order, false otherwise.

Definition at line 534 of file index.h.

operator=()

template<class IndexType >

basic_quadindex<IndexType>& GEO::basic_quadindex< IndexType >::operator= ( const basic_quadindex< IndexType > &  rhs )

default

Assigns a basic_quadindex to this one.

Parameters

[in]

rhs

the basic_quadindex this basic_quadindex should be assigned from

Returns

a reference to this basic_quadindex

operator==()

template<class IndexType >

bool GEO::basic_quadindex< IndexType >::operator== ( const basic_quadindex< IndexType > &  rhs ) const

inline

Compares two basic_quadindex.

Parameters

[in]

rhs

the basic_quadindex to compare this basic_quadindex with.

Returns

true of all indices of this basic_quadindex correspond to the indices in rhs at the same positions, false otherwise.

Definition at line 553 of file index.h.

std::ostream & operator<< ( std::ostream &  out, const basic_quadindex< IndexType > &  Q  )

related

Writes a basic_quadindex to a stream.

Displays all the indices of the basic_quadindex Q.

Parameters

[in]	out	the output stream
[in]	Q	the basic_quadindex to write
