Method Detail

isDiscardExpressions

boolean isDiscardExpressions()

Returns true if the attribute should be discarded if expressions are used

Returns:

whether to discard if expressions are used

isDiscardUndefined

boolean isDiscardUndefined()

Returns true if the attribute should be discarded if it is undefined

Returns:

whether to discard if the attribute is undefined

isOperationParameterDiscardable

boolean isOperationParameterDiscardable(PathAddress address,
                                        String attributeName,
                                        org.jboss.dmr.ModelNode attributeValue,
                                        org.jboss.dmr.ModelNode operation,
                                        TransformationContext context)

Gets whether the given operation parameter can be discarded

Parameters:

address - the address of the operation

attributeName - the name of the operation parameter

attributeValue - the value of the operation parameter

operation - the operation executed. This is unmodifiable.

context - the context of the transformation

Returns:

true if the operation parameter value should be discarded, false otherwise.

isResourceAttributeDiscardable

boolean isResourceAttributeDiscardable(PathAddress address,
                                       String attributeName,
                                       org.jboss.dmr.ModelNode attributeValue,
                                       TransformationContext context)

Gets whether the given attribute can be discarded

Parameters:

address - the address of the resource

attributeName - the name of the attribute

attributeValue - the value of the attribute

context - the context of the transformation

Returns:

true if the attribute value should be discarded, false otherwise.
