Detailed Description

template<typename VECTOR>
class geos::BlockVector< VECTOR >

Concrete representation of a block vector.

Template Parameters

VECTOR

type of sub-vectors

This extends BlockVectorView class by providing storage for sub-block vectors. The VECTOR type needs to be default-constructible.

Definition at line 36 of file BlockVector.hpp.

Constructor & Destructor Documentation

BlockVector() [1/4]

template<typename VECTOR >

geos::BlockVector< VECTOR >::BlockVector ( localIndex const  nBlocks )

inlineexplicit

Create a vector of nBlocks blocks.

Parameters

nBlocks

Number of blocks

Definition at line 47 of file BlockVector.hpp.

BlockVector() [2/4]

template<typename VECTOR >

geos::BlockVector< VECTOR >::BlockVector ( BlockVector< VECTOR > const &  rhs )

inline

Copy constructor that performs a deep copy of each sub-vector.

Parameters

rhs	the block vector to copy

Definition at line 65 of file BlockVector.hpp.

BlockVector() [3/4]

template<typename VECTOR >

geos::BlockVector< VECTOR >::BlockVector ( BlockVector< VECTOR > &&  rhs )

inline

Move constructor.

Parameters

rhs	the block vector to move from

Definition at line 76 of file BlockVector.hpp.

BlockVector() [4/4]

template<typename VECTOR >

geos::BlockVector< VECTOR >::BlockVector ( BlockVectorView< VECTOR > const &  rhs )

inlineexplicit

Conversion constructor from a compatible view with a deep copy of each sub-vector.

Parameters

rhs	the block vector view to copy from

Note

declared explicit to avoid unintended deep copying

Definition at line 88 of file BlockVector.hpp.

Member Function Documentation

operator=() [1/2]

template<typename VECTOR >

BlockVector& geos::BlockVector< VECTOR >::operator= ( BlockVector< VECTOR > &&  x )

inlinenoexcept

Move assignment.

Parameters

x	the vector to move from

Returns

reference to this

Definition at line 115 of file BlockVector.hpp.

operator=() [2/2]

template<typename VECTOR >

BlockVector& geos::BlockVector< VECTOR >::operator= ( BlockVector< VECTOR > const &  x )

inline

Copy assignment.

Parameters

x	the vector to copy

Returns

reference to this

Definition at line 103 of file BlockVector.hpp.

resize()

template<typename VECTOR >

void geos::BlockVector< VECTOR >::resize ( localIndex const  nBlocks )

inline

Resize to a different number of blocks.

Parameters

nBlocks

the new number of blocks

Note

If the new number of blocks is larger than the previous, new vectors will not be initialized. It is the user's responsibility to do that.

Definition at line 134 of file BlockVector.hpp.
