Constructor

Parameters:

discardExpressions - true if the attribute should be discarded if expressions are used

discardUndefined - true if the attribute should be discarded if expressions are used

DefaultDiscardAttributeChecker

public DefaultDiscardAttributeChecker()

Constructor. Sets it up with discardExpressions==false and discardUndefined==true

Method Detail

isDiscardExpressions

public boolean isDiscardExpressions()

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

Specified by:

isDiscardExpressions in interface DiscardAttributeChecker

Returns:

whether to discard if expressions are used

isDiscardUndefined

public boolean isDiscardUndefined()

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

Specified by:

isDiscardUndefined in interface DiscardAttributeChecker

Returns:

whether to discard if the attribute is undefined

isOperationParameterDiscardable

public 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

Specified by:

isOperationParameterDiscardable in interface DiscardAttributeChecker

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

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

Gets whether the given attribute can be discarded

Specified by:

isResourceAttributeDiscardable in interface DiscardAttributeChecker

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.

isValueDiscardable

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

Gets called by the default implementations of isOperationParameterDiscardable(PathAddress, String, ModelNode, ModelNode, TransformationContext) and isResourceAttributeDiscardable(PathAddress, String, ModelNode, TransformationContext).

Parameters:

address - the address of the operation or resource

attributeName - the name of the attribute

attributeValue - the value of the attribute

context - the context of the transformation

Returns:

true if the attribute or parameter value is not understandable by the target process and so needs to be rejected, false otherwise.
