Creates instance from XACML AttributeSelector without ContextSelectorId

Parameters:

attributeSelectorCategory - XACML AttributeSelector's Category

attributeSelectorPath - XACML AttributeSelector's Path

xPathCompiler - XPath compiler used for compiling attributeSelectorElement.getPath() and XPath given by attributeSelectorElement.getContextSelectorId().

attributeFactory - attribute factory to create the AttributeValue(s) from the XML node(s) resolved by XPath

Returns:

instance of AttributeSelector expression

Throws:

IllegalArgumentException - if attributeSelectorElement == null || xPathCompiler == null || attributeFactory == null; or attributeSelectorElement.getContextSelectorId() != null but attributeProvider == null; or attributeSelectorElement.getPath() is not a valid XPath expression

Creates instance from XACML AttributeSelector with ContextSelectorId

Parameters:

attributeSelectorElement - XACML AttributeSelector

xPathCompiler - XPATH compiler used for compiling attributeSelectorElement.getPath() and XPath given by attributeSelectorElement.getContextSelectorId() if not null

contextSelectorAttributeProvider - AttributeProvider for finding value of the attribute identified by ContextSelectorId in attributeSelectorElement; may be null if attributeSelectorElement.getContextSelectorId() == null

attributeFactory - attribute factory to create the AttributeValue(s) from the XML node(s) resolved by XPath

Returns:

instance of AttributeSelector expression

Throws:

IllegalArgumentException - if attributeSelectorElement == null || xPathCompiler == null || attributeFactory == null; or attributeSelectorElement.getContextSelectorId() != null but attributeProvider == null; or attributeSelectorElement.getPath() is not a valid XPath expression
