Constructor Detail

ImageTiledLayer

protected ImageTiledLayer(TileInfo tileInfo,
                          Envelope fullExtent)

Creates an ImageTiledLayer based on tile info and full extent. This constructor needs to be called by any custom layers that extend ImageTiledLayer.

Parameters:

tileInfo - info about the tiling scheme

fullExtent - full extent of the layer

Throws:

IllegalArgumentException - if tileInfo is null

IllegalArgumentException - if fullExtent is null

Since:

100.1.0

Method Detail

getBufferSize

public ImageTiledLayer.BufferSize getBufferSize()

Gets the buffer size.

Returns:

the buffer size

Since:

100.0.0

setBufferSize

public void setBufferSize(ImageTiledLayer.BufferSize bufferSize)

Sets the buffer size. This is used to indicate whether or not tiles outside of the current visible extent should be fetched. This can be none, small, medium or large.

Parameters:

bufferSize - the new buffer size

Since:

100.0.0

getNoDataTileBehavior

public ImageTiledLayer.NoDataTileBehavior getNoDataTileBehavior()

Gets the ImageTiledLayer.NoDataTileBehavior for the ImageTiledLayer.

Returns:

the NoDataTileBehavior for the ImageTiledLayer

Since:

100.1.0

setNoDataTileBehavior

public void setNoDataTileBehavior(ImageTiledLayer.NoDataTileBehavior noDataTileBehavior)

Sets the ImageTiledLayer.NoDataTileBehavior for the ImageTiledLayer. The behavior cannot be changed once the layer is loaded.

Parameters:

noDataTileBehavior - the desired NoDataTileBehavior

Throws:

IllegalArgumentException - if noDataTileBehavior is null

ArcGISRuntimeException - if this method is called after the layer is loaded

Since:

100.1.0

getTileInfo

public TileInfo getTileInfo()

Returns information on the tile scheme used by the layer.

Returns:

information on the tile scheme used by the layer

Since:

100.0.0

getTile

protected abstract byte[] getTile(TileKey tileKey)

Gets the encoded bytes that represents a tile for the given tile key. The encoding must match TileInfo specified in the constructor ImageTiledLayer(TileInfo, Envelope).

Parameters:

tileKey - key for the expected tile

Returns:

the encoded bytes that represent the tile for the given tile key

Since:

100.1.0
