org.pdf4j.saxon.query.StaticQueryContext

StaticQueryContext contains information used to build a StaticContext for use when processing XQuery expressions.

Despite its name, StaticQueryContext no longer implements the StaticContext interface, which means it cannot be used directly by Saxon when parsing a query. Instead it is first copied to create a QueryModule object, which does implement the StaticContext interface.

The application constructs a StaticQueryContext and initializes it with information about the context, for example, default namespaces, base URI, and so on. When a query is compiled using this StaticQueryContext, the query parser makes a copy of the StaticQueryContext and uses this internally, modifying it with information obtained from the query prolog, as well as information such as namespace and variable declarations that can occur at any point in the query. The query parser does not modify the original StaticQueryContext supplied by the calling application, which may therefore be used for compiling multiple queries, serially or even in multiple threads.

This class forms part of Saxon's published XQuery API. Methods that are considered stable are labelled with the JavaDoc "since" tag. The value 8.4 indicates a method introduced at or before Saxon 8.4; other values indicate the version at which the method was introduced.

In the longer term, this entire API may at some stage be superseded by a proposed standard Java API for XQuery.
