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 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.

Parameters:

sroot - The root stylesheet.

Throws:

TransformerException -

Overrides:

compose in class ElemTemplateElement

getXSLToken

public int getXSLToken()

Get an int constant identifying the type of element.

Returns:

The token ID for this element

Overrides:

getXSLToken in class ElemTemplateElement

Constants

getNodeName

public java.lang.String getNodeName()

Return the node name.

Returns:

the element's name

Overrides:

getNodeName in class ElemTemplateElement

execute

public void execute(TransformerImpl transformer)
             throws 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.

Parameters:

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

Throws:
