int	getNumOperations() The number of operations supported by the GP_GridCoverageProcessor.
GP_Operation	getOperation(int index) Retrieve a grid processing operation information.

Method Detail

getMetadataNames

String[] getMetadataNames()
                          throws RemoteException

Retrieve the list of metadata keywords for the interface.
An empty list will returned if no metadata is available.

Returns:

the list of metadata keywords for the interface.

Throws:

RemoteException - if a remote method call failed.

getNumOperations

int getNumOperations()
                     throws RemoteException

The number of operations supported by the GP_GridCoverageProcessor.

Returns:

the number of operations supported by the GP_GridCoverageProcessor.

Throws:

RemoteException - if a remote method call failed.

getMetadataValue

String getMetadataValue(String name)
                        throws RemoteException

Retrieve the metadata value for a given metadata name.

Parameters:

name - Metadata keyword for which to retrieve metadata.

Returns:

the metadata value for a given metadata name.

Throws:

RemoteException - if a remote method call failed.

getOperation

GP_Operation getOperation(int index)
                          throws RemoteException

Retrieve a grid processing operation information. The operation information will contain the name of the operation as well as a list of its parameters.

Parameters:

index - Index for which to retrieve the operation information.

Returns:

a grid processing operation information.

Throws:

RemoteException - if a remote method call failed.

analyse

GP_GridAnalysis analyse(GC_GridCoverage gridCoverage)
                        throws RemoteException

Creates a GP_GridAnalysis interface from a grid coverage. This allows grid analysis functions to be performed on a grid coverage.

Parameters:

gridCoverage - Grid coverage on which the analysis will be performed.

Returns:

a new GP_GridAnalysis interface.

Throws:

RemoteException - if a remote method call failed.

doOperation

GC_GridCoverage doOperation(String operationName,
                            GC_Parameter[] parameters)
                            throws RemoteException

Apply a process operation to a grid coverage.

Parameters:

operationName - Name of the operation to be applied to the grid coverage.

parameters - List of name value pairs for the parameters required for the operation.

Returns:

the grid coverage which has been applied the process operation.

Throws:

RemoteException - if a remote method call failed.
