FunSparseMatrix

Constructor where validity and value are determined by validator and valueFun separately. This is somewhat more efficient in the case that valueFun is expensive as validator is called separately.

Constructor where validity and value are determined by the same underlying function. Note that valueFun is always called, results are not cached.

Get an iterable with all valid indices in the matrix

The height of the matrix

The width of the matrix

For copying allow retrieving the/a validator function

Get all elements in the matrix as sequence.

Determine whether the content of this matrix is the same as the other by checking equality on the cell values. Sparse matrices with different dimensions, but the same valid indices can be equal.

Creates a copy of the matrix of an appropriate type with the same content.

Perform the action for each value in the (sparse) matrix.

Perform the action for each index in the (sparse) matrix. This skips sparse indices.

Whatever the actual type, allow them to be read to read any value. Implementations are expected to use more precise return types.

This function can be used to determine whether the given coordinates are valid. Returns true if valid. This function works on any value for the coordinates and should return false for all values out of range (x<0 || x>=[maxWidth]), (y<0 || y>=[maxHeight]).

Get an iterator over all elements in the (sparse) matrix.

A map function that creates a new (sparse) matrix with each cell mapped by transform.

A map implementation that creates a boolean sparse matrix based upon the receiver and the transformation function.

Create a new SparseIntMatrix with the dimensions of the original where the value of each cell is the result of applying the transform to the value of the cell in the original.
