Constructor Detail

ElemVariable

public ElemVariable()

Constructor ElemVariable

ElemVariable

public ElemVariable(ElemVariable param)
             throws TransformerException

Copy constructor.

Parameters:

param - An element created from an xsl:variable

Throws:

TransformerException -

Method Detail

setSelect

public void setSelect(XPath v)

Set the "select" attribute. If the variable-binding element has a select attribute, then the value of the attribute must be an expression and the value of the variable is the object that results from evaluating the expression. In this case, the content of the variable must be empty.

Parameters:

v - Value to set for the "select" attribute.

getSelect

public XPath getSelect()

Get the "select" attribute. If the variable-binding element has a select attribute, then the value of the attribute must be an expression and the value of the variable is the object that results from evaluating the expression. In this case, the content of the variable must be empty.

Returns:

Value of the "select" attribute.

setName

public void setName(QName v)

Set the "name" attribute. Both xsl:variable and xsl:param have a required name attribute, which specifies the name of the variable. The value of the name attribute is a QName, which is expanded as described in [2.4 Qualified Names].

Parameters:

v - Value to set for the "name" attribute.

See Also:

qname in XSLT Specification

getName

public QName getName()

Get the "name" attribute. Both xsl:variable and xsl:param have a required name attribute, which specifies the name of the variable. The value of the name attribute is a QName, which is expanded as described in [2.4 Qualified Names].

Returns:

Value of the "name" attribute.

See Also:

qname in XSLT Specification

setIsTopLevel

public void setIsTopLevel(boolean v)

Set if this is a top-level variable or param, or not.

Parameters:

v - Boolean indicating whether this is a top-level variable or param, or not.

See Also:

top-level-variables in XSLT Specification

getIsTopLevel

public boolean getIsTopLevel()

Get if this is a top-level variable or param, or not.

Returns:

Boolean indicating whether this is a top-level variable or param, or not.

See Also:

top-level-variables in XSLT Specification

getXSLToken

public int getXSLToken()

Get an integer representation of the element type.

Returns:

An integer representation of the element, defined in the Constants class.

Overrides:

getXSLToken in class ElemTemplateElement

See Also:

Constants

getNodeName

public java.lang.String getNodeName()

Return the node name.

Returns:

The node name

Overrides:

getNodeName in class ElemTemplateElement

execute

public void execute(TransformerImpl transformer,
                    Node sourceNode,
                    QName mode)
             throws TransformerException

Execute a variable declaration and push it onto the variable stack.

Parameters:

transformer - non-null reference to the the current transform-time state.

sourceNode - non-null reference to the current source node.

mode - reference, which may be null, to the current mode.

Throws:

TransformerException -

Overrides:

execute in class ElemTemplateElement

See Also:

variables in XSLT Specification

getValue

public XObject getValue(TransformerImpl transformer,
                        Node sourceNode)
                 throws TransformerException

Get the XObject representation of the variable.

Parameters:

transformer - non-null reference to the the current transform-time state.

sourceNode - non-null reference to the current source node.

Returns:

the XObject representation of the variable.

Throws:

TransformerException -

recompose

public void recompose(StylesheetRoot root)

This function is called during recomposition to control how this element is composed.

Parameters:

root - The root stylesheet for this transformation.

Overrides:

recompose in class ElemTemplateElement
