Constant Field Values

m_test

private XPath m_test

The xsl:if element must have a test attribute, which specifies an expression.

Constructor Detail

ElemIf

public ElemIf()

Method Detail

setTest

public void setTest(XPath v)

Set the "test" attribute. The xsl:if element must have a test attribute, which specifies an expression.

Parameters:

v - test attribute to set

getTest

public XPath getTest()

Get the "test" attribute. The xsl:if element must have a test attribute, which specifies an expression.

Returns:

the "test" attribute for this element.

compose

public void compose(StylesheetRoot sroot)
             throws javax.xml.transform.TransformerException

This function is called after everything else has been recomposed, and allows the template to set remaining values that may be based on some other property that depends on recomposition.

Overrides:

compose in class ElemTemplateElement

Parameters:

sroot - The root stylesheet.

Throws:

javax.xml.transform.TransformerException

getXSLToken

public int getXSLToken()

Get an int constant identifying the type of element.

Overrides:

getXSLToken in class ElemTemplateElement

Returns:

The token ID for this element

See Also:

Constants

getNodeName

public java.lang.String getNodeName()

Return the node name.

Specified by:

getNodeName in interface org.w3c.dom.Node

Overrides:

getNodeName in class ElemTemplateElement

Returns:

the element's name

execute

public void execute(TransformerImpl transformer)
             throws javax.xml.transform.TransformerException

Conditionally execute a sub-template. The expression is evaluated and the resulting object is converted to a boolean as if by a call to the boolean function. If the result is true, then the content template is instantiated; otherwise, nothing is created.

Overrides:

execute in class ElemTemplateElement

Parameters:

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

Throws:

javax.xml.transform.TransformerException

callChildVisitors

protected void callChildVisitors(XSLTVisitor visitor,
                                 boolean callAttrs)

Call the children visitors.

Overrides:

callChildVisitors in class ElemTemplateElement

Parameters:

visitor - The visitor whose appropriate method will be called.
