Member Function Documentation

void copy_data ( const SGReferencedData &  orig )

protectedvirtual

copy data

Implements SGReferencedData.

Definition at line 67 of file SGMatrixList.cpp.

void copy_refcount ( const SGReferencedData &  orig )

protectedinherited

copy refcount

Definition at line 55 of file SGReferencedData.cpp.

void free_data ( )

protectedvirtual

free data

Implements SGReferencedData.

Definition at line 81 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 49 of file SGMatrixList.cpp.

void init_data ( )

protectedvirtual

initialize empty data

Implements SGReferencedData.

Definition at line 74 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 55 of file SGMatrixList.cpp.

int32_t ref ( )

protectedinherited

increase reference counter

Returns

reference count

Definition at line 64 of file SGReferencedData.cpp.

int32_t ref_count ( )

inherited

display reference counter

Returns

reference count

Definition at line 41 of file SGReferencedData.cpp.

void set_matrix	(	index_t	index,
		const SGMatrix< T >	matrix
	)

set a matrix of the list

Parameters

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

Definition at line 61 of file SGMatrixList.cpp.

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 89 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 84 of file SGReferencedData.cpp.
