Method Detail

getElementValidator

public ParameterValidator getElementValidator()

The validator used to validate elements in the list.

Returns:

the element validator

parse

public org.jboss.dmr.ModelNode parse(String value,
                                     XMLStreamReader reader)
                              throws XMLStreamException

Creates and returns a ModelNode using the given value after first validating the node against this object's element validator.

If value is null an undefined node will be returned.

Parameters:

value - the value. Will be trimmed before use if not null.

reader - XMLStreamReader from which the location from which the attribute value was read can be obtained and used in any XMLStreamException, in case the given value is invalid.

Returns:

ModelNode representing the parsed value

Throws:

XMLStreamException - if value is not valid

parseAndAddParameterElement(String, ModelNode, XMLStreamReader)

parseAndAddParameterElement

public void parseAndAddParameterElement(String value,
                                        org.jboss.dmr.ModelNode operation,
                                        XMLStreamReader reader)
                                 throws XMLStreamException

Creates a ModelNode using the given value after first validating the node against this object's element validator, and then stores it in the given operation model node as an element in a ModelType.LIST value in a key/value pair whose key is this attribute's name.

If value is null an undefined node will be stored if such a value is acceptable to the validator.

The expected usage of this method is in parsers seeking to build up an operation to store their parsed data into the configuration.

Parameters:

value - the value. Will be trimmed before use if not null.

operation - model node of type ModelType.OBJECT into which the parsed value should be stored

reader - XMLStreamReader from which the location from which the attribute value was read can be obtained and used in any XMLStreamException, in case the given value is invalid.

Throws:

XMLStreamException - if value is not valid

                              XMLStreamWriter writer)
                       throws XMLStreamException

Description copied from class: AttributeDefinition

Marshalls the value from the given resourceModel as an xml element, if it is marshallable.

Overrides:

marshallAsElement in class AttributeDefinition

Parameters:

resourceModel - the model, a non-null node of ModelType.OBJECT.

writer - stream writer to use for writing the attribute

Throws:

XMLStreamException - if thrown by writer

convertParameterExpressions

protected org.jboss.dmr.ModelNode convertParameterExpressions(org.jboss.dmr.ModelNode parameter)

Iterates through the elements in the parameter list, calling convertParameterElementExpressions(ModelNode) for each.

Note that the default implementation of convertParameterElementExpressions(ModelNode) will only convert simple ModelType.STRING elements. If users need to handle complex elements with embedded expressions, they should use a subclass that overrides that method.

Examine the given operation parameter value for any expression syntax, converting the relevant node to ModelType.EXPRESSION if such is supported.

This implementation checks if expressions are allowed and if so, calls AttributeDefinition.convertStringExpression(ModelNode) to convert a ModelType.STRING to a ModelType.EXPRESSION. No other conversions are performed. For use cases requiring more complex behavior, a subclass that overrides this method should be used.

If expressions are supported this implementation also checks if the attribute type is one of the complex DMR types. If it is, an IllegalStateException is thrown, as this implementation cannot properly handle such a combination, and a subclass that overrides this method should be used.

Overrides:

convertParameterExpressions in class AttributeDefinition

Parameters:

parameter - the node to examine. Cannot not be null

Returns:

a node matching parameter but with expressions converted, or the original parameter if no conversion was performed. Will not return null

convertParameterElementExpressions

protected org.jboss.dmr.ModelNode convertParameterElementExpressions(org.jboss.dmr.ModelNode parameterElement)

Examine the given element of a parameter list for any expression syntax, converting the relevant node to ModelType.EXPRESSION if such is supported. This implementation will only convert elements of ModelType.STRING. Subclasses that need to handle complex elements should override this method.

Parameters:

parameterElement - the node to examine. Will not be null

Returns:

the parameter element with expressions converted, or the original parameter if no conversion was performed Cannot return null

                                      throws XMLStreamException

Deprecated. in favour of using attribute parser

parses whole value as list attribute and uses "," separator splitting list elements

Parameters:

value - String with "," separated string elements

operation - operation to with this list elements are added

reader - xml reader from where reading is be done

Throws:

XMLStreamException
