Constructor Detail

### ElemSort

    public ElemSort()

Method Detail

### setSelect

    public void setSelect(XPath v)

  Set the "select" attribute. xsl:sort has a select attribute whose value is an expression. For each node to be processed, the expression is evaluated with that node as the current node and with the complete list of nodes being processed in unsorted order as the current node list. The resulting object is converted to a string as if by a call to the string function; this string is used as the sort key for that node. The default value of the select attribute is ., which will cause the string-value of the current node to be used as the sort key.
  Parameters:
    `v` - Value to set for the "select" attribute

### getSelect

    public XPath getSelect()

  Get the "select" attribute. xsl:sort has a select attribute whose value is an expression. For each node to be processed, the expression is evaluated with that node as the current node and with the complete list of nodes being processed in unsorted order as the current node list. The resulting object is converted to a string as if by a call to the string function; this string is used as the sort key for that node. The default value of the select attribute is ., which will cause the string-value of the current node to be used as the sort key.
  Returns:
    The value of the "select" attribute

### setLang

    public void setLang(AVT v)

  Set the "lang" attribute. lang specifies the language of the sort keys; it has the same range of values as xml:lang [XML]; if no lang value is specified, the language should be determined from the system environment.
  Parameters:
    `v` - The value to set for the "lang" attribute

### getLang

    public AVT getLang()

  Get the "lang" attribute. lang specifies the language of the sort keys; it has the same range of values as xml:lang [XML]; if no lang value is specified, the language should be determined from the system environment.
  Returns:
    The value of the "lang" attribute

### setDataType

    public void setDataType(AVT v)

  Set the "data-type" attribute. `data-type` specifies the data type of the strings; the following values are allowed:
  - `text` specifies that the sort keys should be sorted lexicographically in the culturally correct manner for the language specified by `lang`.
  - `number` specifies that the sort keys should be converted to numbers and then sorted according to the numeric value; the sort key is converted to a number as if by a call to the number function; the `lang` attribute is ignored.
  - A QName with a prefix is expanded into an expanded-name as described in [2.4 Qualified Names]; the expanded-name identifies the data-type; the behavior in this case is not specified by this document.

  The default value is `text`.

  > NOTE: The XSL Working Group plans that future versions of XSLT will leverage XML Schemas to define further values for this attribute.

  Parameters:
    `v` - Value to set for the "data-type" attribute

### getDataType

    public AVT getDataType()

  Get the "data-type" attribute. `data-type` specifies the data type of the strings; the following values are allowed:
  - `text` specifies that the sort keys should be sorted lexicographically in the culturally correct manner for the language specified by `lang`.
  - `number` specifies that the sort keys should be converted to numbers and then sorted according to the numeric value; the sort key is converted to a number as if by a call to the number function; the `lang` attribute is ignored.
  - A QName with a prefix is expanded into an expanded-name as described in [2.4 Qualified Names]; the expanded-name identifies the data-type; the behavior in this case is not specified by this document.

  The default value is `text`.

  > NOTE: The XSL Working Group plans that future versions of XSLT will leverage XML Schemas to define further values for this attribute.

  Returns:
    The value of the "data-type" attribute

### setOrder

    public void setOrder(AVT v)

  Set the "order" attribute. order specifies whether the strings should be sorted in ascending or descending order; ascending specifies ascending order; descending specifies descending order; the default is ascending.
  Parameters:
    `v` - The value to set for the "order" attribute

### getOrder

    public AVT getOrder()

  Get the "order" attribute. order specifies whether the strings should be sorted in ascending or descending order; ascending specifies ascending order; descending specifies descending order; the default is ascending.
  Returns:
    The value of the "order" attribute

### setCaseOrder

    public void setCaseOrder(AVT v)

  Set the "case-order" attribute. case-order has the value upper-first or lower-first; this applies when data-type="text", and specifies that upper-case letters should sort before lower-case letters or vice-versa respectively. For example, if lang="en", then A a B b are sorted with case-order="upper-first" and a A b B are sorted with case-order="lower-first". The default value is language dependent.
  Parameters:
    `v` - The value to set for the "case-order" attribute

### getCaseOrder

    public AVT getCaseOrder()

  Get the "case-order" attribute. case-order has the value upper-first or lower-first; this applies when data-type="text", and specifies that upper-case letters should sort before lower-case letters or vice-versa respectively. For example, if lang="en", then A a B b are sorted with case-order="upper-first" and a A b B are sorted with case-order="lower-first". The default value is language dependent.
  Returns:
    The value of the "case-order" attribute

### getXSLToken

    public int getXSLToken()

  Get an int constant identifying the type of element.
  Returns:
    The token ID of the 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

### appendChild

    public Node appendChild(Node newChild)
                     throws DOMException

  Add a child to the child list.
  Parameters:
    `newChild` - Child to add to the child list
  Returns:
    Child just added to the child list
  Throws:
    DOMException -
  Overrides:
    appendChild in class ElemTemplateElement

### 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.
  Overrides:
    compose in class ElemTemplateElement
