XSLLeafNodeConstructor

public XSLLeafNodeConstructor()

Method Detail

prepareAttributesNameAndSelect

protected Expression prepareAttributesNameAndSelect()

Method for use by subclasses (processing-instruction and namespace) that take a name and a select attribute

Returns:

the expression defining the name attribute

isInstruction

public boolean isInstruction()

Determine whether this node is an instruction.

Overrides:

isInstruction in class StyleElement

Returns:

true - it is an instruction

mayContainSequenceConstructor

public 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

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 class StyleElement

Parameters:

decl - the declaration to be validated

Throws:

XPathException - if any error is found during validation

getErrorCodeForSelectPlusContent

protected abstract java.lang.String getErrorCodeForSelectPlusContent()

Get the error code to be returned when the element has a select attribute but is not empty.

Returns:

the error code defined for this condition, for this particular instruction

compileContent

protected void compileContent(Compilation exec,
                              ComponentDeclaration decl,
                              SimpleNodeConstructor inst,
                              Expression separator)
                       throws XPathException

Throws:

XPathException

makeSimpleContentConstructor

public static Expression makeSimpleContentConstructor(Expression select,
                                                      Expression separator,
                                                      StaticContext env)

Construct an expression that implements the rules of "constructing simple content": given an expression to select the base sequence, and an expression to compute the separator, build an (unoptimized) expression to produce the value of the node as a string.

Parameters:

select - the expression that selects the base sequence

separator - the expression that computes the separator

env - the static context

Returns:

an expression that returns a string containing the string value of the constructed node
