Constructor Detail

XSLLocalVariable

public XSLLocalVariable()

Method Detail

getBindingInformation

public SourceBinding getBindingInformation(StructuredQName name)

Ask whether this element contains a binding for a variable with a given name; and if it does, return the source binding information

Overrides:

getBindingInformation in class StyleElement

Parameters:

name - the variable name

Returns:

the binding information if this element binds a variable of this name; otherwise null

isInstruction

public boolean isInstruction()

Determine whether this node is an instruction.

Overrides:

isInstruction in class StyleElement

Returns:

true - it is an instruction (well, it can be, anyway)

prepareAttributes

public void prepareAttributes()
                       throws XPathException

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 class StyleElement

Throws:

XPathException - if a static error is detected

getRequiredType

public SequenceType getRequiredType()

Get the static type of the variable. This is the declared type, unless the value is statically known and constant, in which case it is the actual type of the value.

fixupReferences

public void fixupReferences()
                     throws XPathException

Description copied from class: StyleElement

Fix up references from XPath expressions. Overridden for function declarations and variable declarations

Overrides:

fixupReferences in class StyleElement

Throws:

XPathException - if any references cannot be fixed up.

compileLocalVariable

public void compileLocalVariable(Compilation exec,
                                 ComponentDeclaration decl)
                          throws XPathException

Process this local variable declaration by expanding any sequence constructor and setting the select expression to the result

Parameters:

exec - the executable

decl - the declaration being compiled

Throws:

XPathException - if an error occurs
