Table of variable bindings.

Constructor Detail

SimpleVariableContext

Construct.

Create a new empty variable context.

Method Detail

getVariableValue

public Object getVariableValue(String namespaceURI, String prefix, String localName)

setVariableValue

public void setVariableValue(String namespaceURI, String localName, Object value)

Set the value associated with a variable.

This method sets a variable that is associated with a particular namespace. These variables appear such as $prefix:foo in an XPath expression. Prefix to URI resolution is the responsibility of a NamespaceContext. Variables within a VariableContext are referred to purely based upon their namespace URI, if any.

Parameters: namespaceURI the namespace URI of the variable localName the local name of the variable value The value to be bound to the variable

setVariableValue

public void setVariableValue(String localName, Object value)

Set the value associated with a variable.

This method sets a variable that is not associated with any particular namespace. These variables look like $foo in an XPath expression.

Parameters: localName the local name of the variable value the value to be bound to the variable
