Class CombineDescriptor
Object
OperationDescriptorImpl
CombineDescriptor
- All Implemented Interfaces:
- Serializable, OperationDescriptor, RegistryElementDescriptor
public class CombineDescriptor
- extends OperationDescriptorImpl
The operation descriptor for the Combine
operation. While this descriptor declares
to support 0 RenderedImage
sources, an arbitrary amount of sources can really be
specified. The "0" should be understood as the minimal number of sources required.

OPERATION_NAME
public static final String OPERATION_NAME
- The operation name, which is "org.geotools.Combine".

- Constant Field Values
CombineDescriptor
public CombineDescriptor()
- Constructs the descriptor.
validateSources
protected boolean validateSources(String modeName,
ParameterBlock param,
StringBuffer message)
- Returns
true
if this operation supports the specified mode, and
is capable of handling the given input source(s) for the specified mode.
- Overrides:
validateSources
in class OperationDescriptorImpl
- Parameters:
modeName
- The mode name (usually "Rendered").param
- The parameter block for the operation to performs.message
- A buffer for formatting an error message if any.
validateParameters
protected boolean validateParameters(String modeName,
ParameterBlock param,
StringBuffer message)
- Returns
true
if the parameters are valids. This implementation check
that the number of bands in the source src1 is equals to the number of bands of
source src2.
- Overrides:
validateParameters
in class OperationDescriptorImpl
- Parameters:
modeName
- The mode name (usually "Rendered").param
- The parameter block for the operation to performs.message
- A buffer for formatting an error message if any.
