public class XSLTry extends StyleElement
Handler for xsl:try elements in stylesheet. The xsl:try element contains a sequence constructor or a select expression, which defines the expression to be evaluated, and it may contain one or more xsl:catch elements, which define the value to be returned in the event of dynamic errors.

Method Detail
-
isInstruction
public boolean isInstruction()
Determine whether this node is an instruction.- Overrides:
isInstruction
in classStyleElement
- Returns:
- true - it is an instruction
-
mayContainSequenceConstructor
protected boolean mayContainSequenceConstructor()
Determine whether this type of element is allowed to contain a sequence constructor- Overrides:
mayContainSequenceConstructor
in classStyleElement
- Returns:
- true: yes, it may contain a sequence constructor
-
prepareAttributes
protected void prepareAttributes()
Description copied from class:StyleElement
Set 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:
prepareAttributes
in classStyleElement
-
isPermittedChild
protected boolean isPermittedChild(StyleElement child)
Description copied from class:StyleElement
Check whether a given child is permitted for this element. This method is used when a non-instruction child element such as xsl:sort is encountered in a context where instructions would normally be expected.- Overrides:
isPermittedChild
in classStyleElement
- Parameters:
child
- the child that may or may not be permitted- Returns:
- true if the child is permitted.
-
validate
public void validate(ComponentDeclaration decl) throws XPathException
Description copied from class:StyleElement
Check 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:
validate
in classStyleElement
- Parameters:
decl
- the declaration to be validated- Throws:
XPathException
- if any error is found during validation
-
compile
public Expression compile(Compilation exec, ComponentDeclaration decl) throws XPathException
Description copied from class:StyleElement
Compile the instruction on the stylesheet tree into an executable instruction for use at run-time.- Overrides:
compile
in 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
-
addCatchClause
public void addCatchClause(QNameTest nameTest, Expression catchExpr)
-
