java.lang.Object net.sf.saxon.sxpath.AbstractStaticContext
public abstract class AbstractStaticContext
An abstract and configurable implementation of the StaticContext interface, which defines the static context of an XPath expression.
This class implements those parts of the functionality of a static context that tend to be common to most implementations: simple-valued properties such as base URI and default element namespace; availability of the standard function library; and support for collations.
