Detailed Description

template<class T>
class GEO::vector< T >

Vector with aligned memory allocation.

Class vector is a std::vector that uses a memory-aligned allocator Memory-aligned allocation makes it well suited for SSE/AVX/... vector code generation.

inline

Gets a pointer to the array of elements.

Returns

a pointer to the first element of the vector

Definition at line 806 of file memory.h.

data() [2/2]

template<class T >

const T * GEO::vector< T >::data ( ) const

inline

Gets a pointer to the array of elements.

Returns

a const pointer to the first element of the vector

Definition at line 820 of file memory.h.

operator[]() [1/4]

template<class T >

T & GEO::vector< T >::operator[] ( index_t  i )

inline

Gets a vector element.

Parameters

[in]

i

index of the element

Returns

A reference to the element at position i in the vector.

Definition at line 719 of file memory.h.

operator[]() [2/4]

template<class T >

const T & GEO::vector< T >::operator[] ( index_t  i ) const

inline

Gets a vector element.

Parameters

[in]

i

index of the element

Returns

A const reference to the element at position i in the vector.

Definition at line 730 of file memory.h.

operator[]() [3/4]

template<class T >

T & GEO::vector< T >::operator[] ( signed_index_t  i )

inline

Gets a vector element.

Parameters

[in]

i

index of the element

Returns

A reference to the element at position i in the vector.

Definition at line 740 of file memory.h.

operator[]() [4/4]

template<class T >

const T & GEO::vector< T >::operator[] ( signed_index_t  i ) const

inline

Gets a vector element.

Parameters

i

index of the element

Returns

A const reference to the element at position i in the vector.

Definition at line 751 of file memory.h.

size()

index_t GEO::vector< T >::size ( ) const

inline

Gets the number of elements.

Returns

The actual number of elements in the vector
