Description
| Interface Summary | |
| FunctionLibrary | A FunctionLibrary handles the binding of function calls in XPath (or XQuery) expressions. |
| XSLTFunction | This is a marker interface used to identify functions that are defined in XSLT rather than in XPath |

| Doc | Implement the fn:doc() function - a simplified form of the Document function |
| Document | Implements the XSLT document() function |
| Error | Implement XPath function fn:error() |
| EscapeURI | |
| Evaluate | This class implements the saxon:evaluate(), saxon:expression(), and saxon:eval() extension functions, which are specially-recognized by the system because they need access to parts of the static context |
| Evaluate.PreparedExpression | Inner class PreparedExpression represents a compiled XPath expression together with the standard variables $p1 .. |
| ExecutableFunctionLibrary | An ExecutableFunctionLibrary is a function library that contains definitions of functions for use at run-time. |
| Existence | Implement the exists() and empty() functions |
| ExtensionFunctionCall | This class acts as a container for an extension function defined to call a method in a user-defined class. |
| ExtensionFunctionFactory | This class acts as a factory for creating expressions that call extension functions. |
| Extensions | This class implements functions that are supplied as standard with SAXON, but which are not defined in the XSLT or XPath specifications. |
| ForceCase | This class implements the upper-case() and lower-case() functions |
| FormatDate | Implement the format-date() function in XPath 2.0 |
| FormatNumber | This is the original XSLT 1.0 implementation of format-number using the JDK directly. |
| FormatNumber2 | XSLT 2.0 implementation of format-number() function - removes the dependence on the JDK. |
| FunctionLibraryList | A FunctionLibraryList is a list of FunctionLibraries. |
| Id | The XPath id() function XPath 2.0 version: accepts any sequence as the first parameter; each item in the sequence is taken as an IDREFS value, that is, a space-separated list of ID values. |
| Idref | |
| IndexOf | The XPath 2.0 index-of() function |
| InScopeNamespaces | This class supports fuctions get-in-scope-prefixes() |
| Insert | The XPath 2.0 insert-before() function |
| JavaExtensionLibrary | The JavaExtensionLibrary is a FunctionLibrary that binds XPath function calls to calls on Java methods (or constructors, or fields). |
| Key | |
| Lang | |
| Last | Implement the XPath 1.0 function last() |
| Matches | This class implements the matches() function for regular expression matching |
| Minimax | This class implements the min() and max() functions |
| NamePart | This class supports the name(), local-name(), and namespace-uri() functions from XPath 1.0, and also the XSLT generate-id() function |
| NamespaceForPrefix | This class supports fuction get-namespace-uri-for-prefix() |
| NormalizeSpace | Implement the XPath normalize-space() function |
| NumberFn | Implements the XPath number() function |
| Parse | This class implements the saxon:parse() extension function, which is specially-recognized by the system because it needs access to parts of the static context |
| Position | |
| QNameFn | This class supports the fn:QName() function (previously named fn:expanded-QName()) |
| RegexGroup | |
| Remove | The XPath 2.0 remove() function |
| Replace | This class implements the replace() function for replacing substrings that match a regular expression |
| ResolveQName | This class supports the resolve-QName function in XPath 2.0 |
| ResolveURI | This class supports the resolve-uri() functions in XPath 2.0 |
| Reverse | Implement XPath function fn:reverse() |
| Root | Implement the XPath 2.0 root() function |
| Rounding | This class supports the ceiling(), floor(), round(), and round-to-half-even() functions, and also the abs() function |
| Serialize | This class implements the saxon:serialize() extension function, which is specially-recognized by the system because it needs access to parts of the static context |
| StandardFunction | This class contains static data tables defining the properties of standard functions. |
| StandardFunction.Entry | An entry in the table describing the properties of a function |
| StaticBaseURI | This class supports the static-base-uri() function in XPath 2.0 (added by the working groups on 24 August 2004) |

| Translate | |
| TreatFn | This class supports the XPath 2.0 functions exactly-one(), one-or-more(), zero-or-one(). |
| Unicode | |
| Unordered | XPath 2.0 unordered() function |
| UnparsedEntity | Implements the unparsed-entity-uri() function defined in XSLT 1.0 and the unparsed-entity-public-id() function defined in XSLT 2.0 |
| UnparsedText | |
| VendorFunctionLibrary | The VendorFunctionLibrary represents specially-recognized functions in the Saxon namespace. |
This package provides implementations of all the core functions available for use in XPath expressions. This includes all the functions defined in XPath 1.0 and XSLT 1.0, and a selection of those defined in the working drafts for XPath 2.0.
There is one class for each core function, or for a group of closely-related functions. These all inherit from the class net.sf.saxon.expr.Function.
There is also a class Extensions which implements SAXON-defined extension functions. This contains one method for each extension function.
These classes, although public, will not normally be used directly by user-written Java applications.
