Packages that use Expression | |
org.apache.xalan.templates | Implements the Templates interface,
and defines a set of classes that represent an XSLT stylesheet. |
org.apache.xalan.transformer | In charge of run-time transformations and the production of result trees. |
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. |
