public XSLVariable()

Method Detail

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

Overrides:

prepareAttributes in class XSLGeneralVariable

Throws:

XPathException - if a static error is detected

isInstruction

public boolean isInstruction()

Determine whether this node is an instruction.

Overrides:

isInstruction in class XSLVariableDeclaration

Returns:

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

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.

Specified by:

getRequiredType in class XSLVariableDeclaration

Returns:

the static type declared for the variable

compileDeclaration

public void compileDeclaration(Executable exec,
                               Declaration decl)
                        throws XPathException

Compile: used only for global variables. This method ensures space is available for local variables declared within this global variable

Overrides:

compileDeclaration in class StyleElement

Parameters:

exec - the Executable

decl - the containing top-level declaration, for example xsl:function or xsl:template

Throws:

XPathException - if compilation fails

compileLocalVariable

public LocalVariable compileLocalVariable(Executable exec,
                                          Declaration decl)
                                   throws XPathException

Throws:

XPathException
