String [] kddml.Operators.IO.RepositoryResourceReader.RepositoryResourceReaderSettings.listAttributes  )  [virtual]
 

Returns the list of attributes belonging to the operator specification.

Returns:
String[]

Implements kddml.Operators.OperatorSettings.

Boolean kddml.Operators.IO.RepositoryResourceReader.RepositoryResourceReaderSettings.isRequired String  attribute_name  )  [virtual]
 

Returns true if a given attribute is required in the operator specification. Returns false if the attribute is implied or fixed. Finally, the method returns null if the attribute name do not belong to the list of attributes returned by the method listAttributes().

Parameters:
attribute_name String
Returns:
boolean

Implements kddml.Operators.OperatorSettings.

Boolean kddml.Operators.IO.RepositoryResourceReader.RepositoryResourceReaderSettings.isFixed String  attribute_name  )  [virtual]
 

Returns true if a given attribute is fixed (i.e. constant) in the operator specification. Returns false if the attribute is implied or required. Finally, the method returns null if the attribute name do not belong to the list of attributes returned by the method listAttributes().

Parameters:
attribute_name String
Returns:
boolean

Implements kddml.Operators.OperatorSettings.

String kddml.Operators.IO.RepositoryResourceReader.RepositoryResourceReaderSettings.getDefaultAttributeValue String  attribute_name  )  [virtual]
 

Returns the default value related to a given input attribute. Returns null if the attribute do not admit a default value. An attribute can be given any legal value as a default. The attribute value is not required on each element in the document, but if it is not present, it will appear to be the specified default. If the attribute is implied and it is not included in the element, the operator assumes that this is the attribute value.

Parameters:
attribute_name String
Returns:
String

Implements kddml.Operators.OperatorSettings.

KDDMLScalarType kddml.Operators.IO.RepositoryResourceReader.RepositoryResourceReaderSettings.getAttributeType String  attribute_name  )  [virtual]
 

Returns the type related to a given input attribute. KDDML supports the attribute types as expressed by the class KDDMLScalarType. Returns null if the attribute name do no belong to the list of attributes returned by the method listAttributes().

Parameters:
