Packages that use Expression | |
---|---|
org.apache.xalan.templates | Implements the Templates interface,
and defines a set of classes that represent an XSLT stylesheet.
StylesheetRoot implements the Templates interface, and
extends StylesheetComposed ,
which is a Stylesheet composed of itself
and its included Stylesheet objects. |
org.apache.xalan.transformer | In charge of run-time transformations and the production of result trees.
TransformerImpl implements the
Transformer interface, and is the core representation
of the transformation execution.
For each node in the XML source, TransformerImpl uses the StylesheetRoot and underlying XSLT schema to determine which
template to apply: one of the templates in the StylesheetRoot, a default template rule as specified in the XSLT spec, or
none.
The Transformer works with SerializationHandler to
forward the SAX-like events produced by the
transformation to the appropriate output ContentHandler.
To the degree possible, the parsing of the XML source and application of the Templates object to that source are performed
concurrently in separate threads. |
org.apache.xpath | Implementation of XPath; for the most part, only classes meant for public use are found at this root level of the XPath packages. |
org.apache.xpath.axes | Implementation of XPath LocationPath support -- primary classes are LocPathIterator and UnionPathIterator. |
org.apache.xpath.compiler | Implements an XPath parser which produces an OpMap, and a so-called Compiler which produces an expression tree for fast evaluation. |
org.apache.xpath.functions | Implements XPath functions -- each function is derived from Function, FunctionOneArg, Function2Args, etc, with number-of-arguments checking being applied mainly at compile time -- this package only implements XPath functions, XSLT functions are found in the "templates" package. |
org.apache.xpath.objects | Implementation of XPath polymorphic type objects -- this package will grow as XPath objects are expanded to support XML Schema data types. |
org.apache.xpath.operations | Support for XPath operations, such as +, -, string(), etc. |
org.apache.xpath.patterns | Implementation of XPath nodeTest support, and XSLT pattern matching support. |
