com.saxonica.extfn contains implementations of extension
functions in the Saxon namespace.
See:
Description
| Class Summary | |
|---|---|
| AnalyzeStringFunction | This class implements the extension function saxon:analyze-string(). |
| CompileQuery | This class implements the saxon:compile-query() extension function |
| CompileStylesheet | This class implements the saxon:compile-stylesheet() extension function |
| DeepEqual | Implements the saxon:deep-equal() function, a variant of fn:deep-equal that provides additional control over how the comparison is performed. |
| Deref | This class implements the extension function saxon:ref(). |
| DynamicErrorInfo | This class implements the extension function saxon:dynamic-error-info(), which underpins the variables accessible within saxon:catch such as $err:code etc. |
| Eval | This class implements the saxon:eval() extension function |
| Evaluate | This class implements the saxon:evaluate() extension function |
| Evaluate.EvaluateCall | |
| Evaluate.PreparedExpression | Inner class PreparedExpression represents a compiled XPath expression together with the standard variables $p1 .. |
| EvaluateNode | This class implements the saxon:evaluate-node() extension function |
| ExpressionFn | This class implements the saxon:expression() extension function |
| Extensions | This class implements functions that are supplied as standard with SAXON, but which are not defined in the XSLT or XPath specifications. |
| ExtraFunctionLibrary | The ExtraFunctionLibrary represents additions to the set of Saxon vendor-supplied extension functions that are available only with the Saxon-PE and Saxon-EE editions |
| Find | This class implements the extension function saxon:find, which finds a value within an indexed sequence |
| ForEachGroupFunction | This class implements the extension function saxon:for-each-group(). |
| GeneralFilterFunction | This class provides an abstract framework for a collection of extension functions that have the same general characteristics: (a) the first argument is a sequence, (b) the result is a subset/rearrangement of that sequence, (d) the second argument is a single argument function that is applied to the members of the sequence, (e) the default function if the second argument is omitted is fn:data(), (e) the processing may depend on the default collation. |
| GeneralFilterFunction.GeneralFilterFunctionCall | |
| Highest | This class implements the saxon:highest() extension function |
| HighestOrLowest | This class implements the saxon:highest() and saxon:lowest() extension functions. |
| Index | This class supports the extension function saxon:index, which returns an indexed sequence |
| LastModified | Extension function to determined the last-modified date of a file |
| Leading | This class implements the saxon:leading() extension functions. |
| Lowest | This class implements the saxon:lowest() extension 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 |
| Parse.ParseCall | |
| ParseHtml | Supports the saxon:parse-html() function, a variant of saxon:parse() that differs only in that it uses the TagSoup HTML parser |
| QueryFn | This class implements the saxon:query() extension function |
| Ref | This class implements the extension function saxon:ref(). |
| 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 |
| Sort | This class implements the saxon:sort() extension functions. |
| SubsequenceTestFn | Abstract class providing functionality common to functions saxon:subsequence-before, saxon:subsequence-after etc; contains the concrete implementations of these functions as inner subclasses |
| SubsequenceTestFn.SubsequenceAfterFn | Implement saxon:subsequence-after |
| SubsequenceTestFn.SubsequenceBeforeFn | Implement saxon:subsequence-before |
| SubsequenceTestFn.SubsequenceFromFn | Implement saxon:subsequence-from |
| SubsequenceTestFn.SubsequenceUntilFn | Implement saxon:subsequence-until |
| TransformFn | This class implements the saxon:transform() extension function |
The package com.saxonica.extfn contains implementations of extension
functions in the Saxon namespace.
It also contains the class ExtraFunctionLibrary which acts as a factory class for
generating instances of these extension functions
Most of these classes are implemented using the new "integrated extension function" mechanism
introduced in Saxon 9.2. A few still use the reflection mechanism, these are in class
com.saxonica.extfn.Extensions.
