Method Detail

getName

public String getName()

Specified by:

getName in interface ElementDescriptor

Returns:

The symbolic name used to unambiguously identify this element. E.g. the fully qualified name of a Java class.

getAnnotation

public OperatorMetadata getAnnotation()

getLabel

public String getLabel()

Specified by:

getLabel in interface ElementDescriptor

Returns:

A human-readable version of the symbolic name to be used in user interfaces, or null if not declared.

getAlias

public String getAlias()

Specified by:

getAlias in interface ElementDescriptor

Returns:

A short form of the symbolic name, or null if not declared.

getVersion

public String getVersion()

Specified by:

getVersion in interface OperatorDescriptor

Returns:

The version of the operator, or null if not declared.

getAuthors

public String getAuthors()

Specified by:

getAuthors in interface OperatorDescriptor

Returns:

The author(s) of the operator, or null if not declared.

getCopyright

public String getCopyright()

Specified by:

getCopyright in interface OperatorDescriptor

Returns:

The copyright notice for the operator code, or null if not declared.

getDescription

public String getDescription()

Specified by:

getDescription in interface ElementDescriptor

Returns:

A short description, or null if not declared.

isInternal

public boolean isInternal()

Specified by:

isInternal in interface OperatorDescriptor

Returns:

If true, this operator is considered for internal use only and thus may not be exposed in user interfaces. The default is false.

isAutoWriteDisabled

public boolean isAutoWriteDisabled()

Description copied from interface: OperatorDescriptor

The GPF framework usually writes the target product of either single operators or processing graphs to the file system when executed from the GPT command-line interface or the operator GUI.

If the autoWriteDisabled property is set, this default behaviour is switched off and hence, the operator or graph is responsible for outputting any computed results.

Setting this property on an operator will only be useful, if it either does not generate a new target Product and/or if it does its own outputting of non-Product targets to external files.

Specified by:

isAutoWriteDisabled in interface OperatorDescriptor

Returns:

If true, the framework will prevent automatic writing of the target product to the file system.

getOperatorClass

public Class<? extends Operator> getOperatorClass()

Specified by:

getOperatorClass in interface OperatorDescriptor

Returns:

The operator implementation class.

getSourceProductDescriptors

public SourceProductDescriptor[] getSourceProductDescriptors()

Specified by:

getSourceProductDescriptors in interface OperatorDescriptor

Returns:

The source product descriptors. The array will be empty if the operator does not have any source products.

getSourceProductsDescriptor

public SourceProductsDescriptor getSourceProductsDescriptor()

Specified by:

getSourceProductsDescriptor in interface OperatorDescriptor

Returns:

The source products descriptor, or null if none is declared.

getTargetProductDescriptor

public TargetProductDescriptor getTargetProductDescriptor()

Specified by:

getTargetProductDescriptor in interface OperatorDescriptor

Returns:

The target product descriptor, or null if none is declared.

getTargetPropertyDescriptors

public TargetPropertyDescriptor[] getTargetPropertyDescriptors()

Specified by:

getTargetPropertyDescriptors in interface OperatorDescriptor

Returns:

The target property descriptors. The array will be empty if the operator does not produce any target properties.

getParameterDescriptors

public ParameterDescriptor[] getParameterDescriptors()

Specified by:

getParameterDescriptors in interface OperatorDescriptor

Returns:

The parameter descriptors. The array will be empty if the operator does not have any parameters.
