Method Detail

fetchGridCoordinates

public abstract rx.Observable<AxialCoordinate> fetchGridCoordinates(HexagonalGridBuilder builder)

Fetches a monotonically increasing (from left to right, top to bottom) Set of grid coordinates corresponding to the shape of the requested grid layout.

Parameters:

builder - builder

Returns:

observable

checkParameters

public boolean checkParameters(int gridHeight,
                               int gridWidth)

Checks whether the supplied parameters are valid for the given strategy. For example a hexagonal grid layout only works if the width equals to the height

Parameters:

gridHeight - height

gridWidth - width

Returns:

valid?
