Description copied from class: Command

Executed to operate on an SeConnection, a Command is scheduled for execution on a Session.

Please keep in mind that a Command should be short in duration; you are sharing this SeConnection with other threads.

Parameters:

session - the Session the command is being executed inside

connection - the session's connection, used to interact with ArcSDE

Returns:

the result of the command execution, or null if the command is not meant to return anything (a command meant to return something should fail if not able to)

Throws:

SeException

IllegalArgumentException - if the raster has no CRS, contains no raster attributes, has no pyramids, no bands or no statistics
