Constructor Detail

XSLGeneralVariable

public XSLGeneralVariable()

Method Detail

getSourceBinding

public SourceBinding getSourceBinding()

Get the source binding object that holds information about the declared variable.

Returns:

the binding object

getVariableQName

public StructuredQName getVariableQName()

getObjectName

public StructuredQName getObjectName()

Description copied from class: StyleElement

Get a name identifying the object of the expression, for example a function name, template name, variable name, key name, element name, etc. This is used only where the name is known statically. If there is no name, the value will be null.

Overrides:

getObjectName in class StyleElement

Returns:

the name of the object declared in this element, if any

mayContainSequenceConstructor

protected boolean mayContainSequenceConstructor()

Determine whether this type of element is allowed to contain a template-body

Overrides:

mayContainSequenceConstructor in class StyleElement

Returns:

true: yes, it may contain a template-body

isGlobal

public boolean isGlobal()

Test whether this is a global variable or parameter

Returns:

true if this is global

validate

public void validate(ComponentDeclaration decl)
              throws XPathException

Check that the variable is not already declared, and allocate a slot number

Overrides:

validate in class StyleElement

Parameters:

decl - the declaration being validated. A single XSLVariableDeclaration object may represent multiple declarations if it appears in a stylesheet module that is included/imported more than once

Throws:

XPathException - if any error is found during validation

postValidate

public void postValidate()
                  throws XPathException

Hook to allow additional validation of a parent element immediately after its children have been validated.

Overrides:

postValidate in class StyleElement

Throws:

XPathException - if any error is found during post-traversal validation
