Description
Interface Summary | |
CallableFunction | A callable (XSLT or XQuery) function |
FunctionSignature | The class FunctionSignature represents information about the name, argument types, and result type of a function. |
Instr | This interface represents the key characteristic of an instruction, namely that it can be processed in "push" mode, writing its results to the current outputter. |
Locatable | This interface represents an instruction or expression whose location in a source module is known. |
TailCall | Interface representing a Tail Call. |
Class Summary | |
AnalyzeString | An xsl:analyze-string elements in the stylesheet. |
ApplyImports | An xsl:apply-imports element in the stylesheet |
ApplyTemplates | An instruction representing an xsl:apply-templates element in the stylesheet |
Assign | saxon:assign element in stylesheet. |
Attribute | An instruction derived from an xsl:attribute element in stylesheet, or from an attribute constructor in XQuery |
AttributeSet | The compiled form of an xsl:attribute-set element in the stylesheet. |
Bindery | The Bindery class holds information about variables and their values. |
Block | Implements an imaginary xsl:block instruction which simply evaluates its contents. |
CallTemplate | Instruction representing an xsl:call-template element in the stylesheet. |
Choose | Compiled representation of an xsl:choose or xsl:if element in the stylesheet. |
Comment | An instruction representing an xsl:comment element in the stylesheet. |
Copy | Handler for xsl:copy elements in stylesheet. |
CopyOf | An xsl:copy-of element in the stylesheet. |
DeferredError | This instruction throws an error which was detected at compile time but is not to be raised unless the instruction is actually executed. |
DefiningVariable | This class defines common behaviour across the compiled instructions for xsl:variable and xsl:param. |
Doctype | A saxon:doctype element in the stylesheet. |
DocumentInstr | An instruction to create a document node. |
DummyNamespaceResolver | A summy namespace resolver used when validating QName-valued attributes written to the result tree. |
Element | An instruction representing xsl:element element in the stylesheet. |
ElementCreator | An instruction that creates an element node. |
Executable | A compiled stylesheet in executable form. |
ExprInstruction | This class is an abstract superclass for Instructions that also behave as Expressions. |
FixedAttribute | An instruction derived from an xsl:attribute element in stylesheet, or from an attribute constructor in XQuery. |
FixedElement | An instruction that creates an element node whose name is known statically. |
ForEach | Handler for xsl:for-each elements in a stylesheet. |
ForEachGroup | Handler for xsl:for-each-group elements in stylesheet. |
FunctionInstr | Handler for xsl:function elements in stylesheet (XSLT 2.0). |
GeneralVariable | This class defines common behaviour across xsl:variable, xsl:param, and xsl:with-param; also saxon:assign |
Instruction | Abstract superclass for all instructions in the compiled stylesheet. |
InstructionDetails | Details about an instruction, used when reporting errors and when tracing |
Message | An xsl:message element in the stylesheet. |
Namespace | An xsl:namespace element in the stylesheet. |
NamespaceContext | An object representing a list of Namespaces. |
NextMatch | An xsl:next-match element in the stylesheet |
NumberInstruction | An xsl:number element in the stylesheet. |
Param | The compiled form of an xsl:param element in the stylesheet or an external variable in a Query. |
ProcessingInstruction | An xsl:processing-instruction element in the stylesheet. |
RegexIterator | Class RegexIterator - provides an iterator over matched and unmatched substrings |
ResultDocument | An xsl:result-document (formerly saxon:output) element in the stylesheet. |
SequenceInstruction | An xsl:sequence element in the stylesheet; or a wrapper inserted around the sequence constructor inside other instructions such as xsl:attribute. |
SimpleNodeConstructor | Common superclass for XSLT instructions whose content template produces a text value: xsl:attribute, xsl:comment, xsl:processing-instruction, xsl:namespace, and xsl:text |
Template | An xsl:template element in the style sheet. |
Text | Handler for xsl:text elements (and simple text nodes) in the stylesheet. |
TraceInstruction | A run-time instruction which wraps a real instruction and traces its entry and exit to the TraceListener |
UserFunction | This object represents the compiled form of a user-written function (the source can be either an XSLT stylesheet function or an XQuery function). |
UserFunctionParameter | Run-time object representing a formal argument to a user-defined function |
ValueOf | An xsl:value-of element in the stylesheet. |
Variable | Handler for xsl:variable elements in stylesheet. |
While | Handler for saxon:while elements in stylesheet. |
WithParam | An instruction derived from a xsl:with-param element in the stylesheet. |
Exception Summary | |
SkipInstructionException | This exception is thrown by code when execution of an instruction has failed, and the recovery action is to continue with the next instruction. |
TerminationException | An exception thrown by xsl:message terminate="yes". |
This package provides classes for the compiled representation of the various elements and other instructions found in an XSLT stylesheet.
Instances of these classes are constructed when the stylesheet is compiled. The objects representing the compile-time stylesheet (in package net.sf.saxon.style) can then be discarded and garbage-collected.
The most important class is Instruction, which represents an XSLT Instruction. In most cases these instructions have a one-to-one relationship with instructions in the original source XSLT stylesheet, and the names of the subclasses (for example ApplyImports, ApplyTemplates, Choose) reflect this.
