Constructor Detail

IdentitySelector

public IdentitySelector(String xpath)
                 throws SchemaException

Create a new IdentitySelector.

Parameters:

xpath - the xpath for the IdentitySelector. Must not be null.

Throws:

SchemaException - if xpath is null.

Method Detail

getXPath

public String getXPath()

Return the source XPath expression of this IdentitySelector.

Returns:

the XPath expression defined in this IdentitySelector.

getSelection

public Pattern getSelection()

Return the compiled XPath expression

Returns:

the expression as a Selector object

setXPath

public void setXPath(String xpath)
              throws SchemaException

Sets the XPath expression for this Selector.

Parameters:

xpath - the XPath expression for this IdentitySelector. Must not be null.

Throws:

SchemaException - if xpath is null.

setSelection

public void setSelection(Pattern selection)

Set the compiled XPath expression

Parameters:

selection - the XPath expression compiled into a Pattern object

setNamespaceContext

public void setNamespaceContext(NamespaceResolver resolver)

Set the namespace context. This is needed to allow the assertion to be serialized, so that the namespace context can be replicated when it is reloaded.

Parameters:

resolver - the resolver used to resolve prefixes in the XPath expression to URIs

getNamespaceContext

public NamespaceResolver getNamespaceContext()

Get the namespace context for evaluating the XPath expression

Returns:

the namespace resolver used to resolve namespace prefixes in the XPath expression

setXPathDefaultNamespace

public void setXPathDefaultNamespace(String uri)

Set the XPath default namespace

Parameters:

uri - the XPath default namespace

getXPathDefaultNamespace

public String getXPathDefaultNamespace()

Get the XPath default namespace

Returns:

the XPath default namespace
