Interface Tile


public interface Tile
A small hyper-rectangular representation of data which is part of a tiling scheme. A tile is uniquely defined in a tile matrix by an integer index in each dimension. Tiles can be a coverage subsets, or a feature based representation (e.g. vector tiles).

All methods in this interface return non-null values.

    • getIndices

      long[] getIndices()
      Returns the indices of this tile in the TileMatrix. If this tile was obtained by a call to TileMatrix.getTile(long...), then the returned array contains the indices that were given in that call.

      The returned array contains coordinates in the space defined by the extent of the tiling scheme. As such, it complies with the following constraints:

      Returns:
      indices of this tile in the TileMatrix, as coordinates inside the matrix GridExtent.

    • getStatus

      TileStatus getStatus()
      Returns information about whether the tile failed to load. The return value can be TileStatus.EXISTS or TileStatus.IN_ERROR; other enumeration values should not happen after a user successfully obtained this Tile instance.

      State transition

      TileStatus.EXISTS is not a guarantee that a call to getResource() will succeed. The error may be detected only during the first attempt to read the resource. Consequently, this method may initially return EXISTS, then return IN_ERROR later after the first read attempt.
      Returns:
      information about the availability of this tile.

    • getResource

      Resource getResource() throws DataStoreException
      Returns the tile content as a resource. The resource type is typically GridCoverageResource, but it may also be other types (e.g. vector tiles).
      Returns:
      the tile content.
      Throws:
      DataStoreException - if an error occurred while reading the content.
