Constructor Details

DistanceMatrix

private DistanceMatrix(int size)

Constructs a new square distance matrix with the given dimensions. Note that these dimensions only apply to the type part of the selectivity types stored in this matrix.

Parameters:

size - The matrix dimensions (number of node types).

DistanceMatrix

private DistanceMatrix(int rows,
 int cols)

Constructs a new distance matrix with the given dimensions. Note that these dimensions only apply to the type part of the selectivity types stored in this matrix.

Parameters:

rows - The number of rows in the matrix.

cols - The number of columns in the matrix.

Method Details

overwrite

private void overwrite(SelectivityGraph.DistanceMatrix data)

Overwrites all the data in this matrix with data from the given other matrix effectively making this matrix a copy of the given matrix.

Parameters:

data - The matrix to copy from.
