Detailed Description

MatrixLazyReader allows to read a row or a column from file, on demand.

It is useful to read partially very large matrices.

The default implementation does just nothing.

Member Function Documentation

◆ freeColumn()

virtual void aims::SparseOrDenseMatrix::MatrixLazyReader::freeColumn ( int32_t  )

◆ freeRow()

virtual void aims::SparseOrDenseMatrix::MatrixLazyReader::freeRow ( int32_t  )
inlinevirtual

Definition at line 73 of file sparseordensematrix.h.

◆ hasColumn()

virtual bool aims::SparseOrDenseMatrix::MatrixLazyReader::hasColumn ( int32_t  ) const

tells if column s2 has already been read.

If so, SparseOrDenseMatrix::readColumn will not read it again.

Definition at line 67 of file sparseordensematrix.h.

◆ hasRow()

virtual bool aims::SparseOrDenseMatrix::MatrixLazyReader::hasRow ( int32_t  ) const
inlinevirtual

tells if row s1 has already been read.

If so, SparseOrDenseMatrix::readRow will not read it again.
