Package net.sf.saxon.style
Class XSLCatch
- All Implemented Interfaces:
Source,SourceLocator,GroundedValue,Item,MutableNodeInfo,NamespaceResolver,NodeInfo,Sequence,Location,SteppingNode<NodeImpl>,SiblingCountingNode,Locator
Handler for xsl:catch elements in stylesheet.
The xsl:catch element has a mandatory attribute errors, a space-separated list of NameTests defining
which errors are caught. If an error is caught, the value to be returned may be defined either by a select
attribute or by the content of the saxon:catch element.

Method Details
-
isInstruction
public boolean isInstruction()Determine whether this node is an instruction.- Overrides:
isInstructionin classStyleElement- Returns:
- true - it is an instruction
-
mayContainSequenceConstructor
public boolean mayContainSequenceConstructor()Determine whether this type of element is allowed to contain a template-body- Overrides:
mayContainSequenceConstructorin classStyleElement- Returns:
- true: yes, it may contain a template-body
-
seesAvuncularVariables
protected boolean seesAvuncularVariables()Ask whether variables declared in an "uncle" element are visible.- Overrides:
seesAvuncularVariablesin classStyleElement- Returns:
- true for all elements except xsl:fallback and saxon:catch
-
prepareAttributes
public void prepareAttributes()Description copied from class:StyleElementSet the attribute list for the element. This is called to process the attributes (note the distinction from processAttributes in the superclass). Must be supplied in a subclass- Specified by:
prepareAttributesin classStyleElement
-
validate
Description copied from class:StyleElementCheck that the stylesheet element is valid. This is called once for each element, after the entire tree has been built. As well as validation, it can perform first-time initialisation. The default implementation does nothing; it is normally overriden in subclasses.- Overrides:
validatein classStyleElement- Parameters:
decl- the declaration to be validated- Throws:
XPathException- if any error is found during validation
-
compile
Description copied from class:StyleElementCompile the instruction on the stylesheet tree into an executable instruction for use at run-time.- Overrides:
compilein classStyleElement- Parameters:
exec- the compilation episodedecl- the containing top-level declaration, for example xsl:function or xsl:template- Returns:
- either a ComputedExpression, or null. The value null is returned when compiling an instruction that returns a no-op, or when compiling a top-level object such as an xsl:template that compiles into something other than an instruction.
- Throws:
XPathException- if validation fails
