Method Detail

isDownloadable

public boolean isDownloadable()

Description copied from interface: DownloadFromServer

Determines if the layer is able to download data and implements the DownloadFromServer interface. A layer that implements the DownloadFromServer interface must return true.

Specified by:

isDownloadable in interface DownloadFromServer

Returns:

true if the layer is able to download data; false, otherwise

isUploadable

public boolean isUploadable()

Description copied from interface: UploadToServer

Determines if the layer is able to upload data and implements the UploadToServer interface. A layer that implements the UploadToServer interface must return true.

Specified by:

isUploadable in interface UploadToServer

Returns:

true if the layer is able to upload data; false, otherwise

requiresUploadToServer

public boolean requiresUploadToServer()

Description copied from interface: UploadToServer

Determines if the data managed by this layer needs to be uploaded to the server because it contains modified data.

Specified by:

requiresUploadToServer in interface UploadToServer
