Definition at line 22 of file SGMatrixList.cpp.

SGMatrixList	(	int32_t	nmats,
		bool	ref_counting = true
	)

Member Function Documentation

void copy_data ( SGReferencedData const &  orig )

protectedvirtual

copy data

Implements SGReferencedData.

Definition at line 50 of file SGMatrixList.cpp.

void copy_refcount ( const SGReferencedData &  orig )

protectedinherited

copy refcount

Definition at line 102 of file SGReferencedData.h.

void free_data ( )

protectedvirtual

free data

Implements SGReferencedData.

Definition at line 64 of file SGMatrixList.cpp.

SGMatrix<T>& get_matrix

(

index_t

index

)

const

get a matrix of the list

Parameters

index

matrix index, index must be less than num_matrices although no check is performed in the method

Returns

the matrix at position index of the list

Definition at line 46 of file SGMatrixList.h.

void init_data ( )

protectedvirtual

initialize empty data

Implements SGReferencedData.

Definition at line 57 of file SGMatrixList.cpp.

SGMatrix<T>& operator[]

(

index_t

index

)

const

operator overload to get a matrix for read & write access

Parameters

index

matrix index, index must be less than num_matrices although no check is performed in the method

Returns

the matrix at position index of the list

Definition at line 58 of file SGMatrixList.h.

int32_t ref ( )

protectedinherited

increase reference counter

Returns

reference count

Definition at line 111 of file SGReferencedData.h.

int32_t ref_count ( )

inherited

display reference counter

Returns

reference count

Definition at line 81 of file SGReferencedData.h.

SGMatrixList< T > split ( SGMatrix< T >  matrix, int32_t  num_components  )

static

divide the matrix into a list of matrices. Each of the new matrices has the same number of rows as the original so the splits to the original matrix are done column-wise.

Parameters

matrix	matrix to split
num_components	number of new matrices

Returns

list of matrices

Definition at line 87 of file SGMatrixList.cpp.

int32_t unref ( )

protectedinherited

decrement reference counter and deallocate object if refcount is zero before or after decrementing it

Returns

reference count

Definition at line 136 of file SGReferencedData.h.
