Constructor Summary
`ElemIf()`

Method Summary
`void` `compose(StylesheetRoot sroot)` 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.
`void` `execute(TransformerImpl transformer)` Conditionally execute a sub-template.
`java.lang.String` `getNodeName()` Return the node name.
`XPath` `getTest()` Get the "test" attribute.
`int` `getXSLToken()` Get an int constant identifying the type of element.
`void` `setTest(XPath v)` Set the "test" attribute.

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 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
  See Also:
    `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:
    TransformerException -
  Overrides:
    execute in class ElemTemplateElement
