public AnnotationOperatorDescriptor(Class<? extends Operator> operatorType,
                                    OperatorMetadata annotation)
```
- 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.
