ElemUse

public ElemUse()

Method Detail

setUseAttributeSets

public void setUseAttributeSets(Vector v)

Set the "use-attribute-sets" attribute. Attribute sets are used by specifying a use-attribute-sets attribute on xsl:element, xsl:copy (see [7.5 Copying]) or xsl:attribute-set elements. The value of the use-attribute-sets attribute is a whitespace-separated list of names of attribute sets. Each name is specified as a QName, which is expanded as described in [2.4 Qualified Names].

Parameters:

v - The value to set for the "use-attribute-sets" attribute.

setUseAttributeSets

public void setUseAttributeSets(QName[] v)

Set the "use-attribute-sets" attribute. Attribute sets are used by specifying a use-attribute-sets attribute on xsl:element, xsl:copy (see [7.5 Copying]) or xsl:attribute-set elements. The value of the use-attribute-sets attribute is a whitespace-separated list of names of attribute sets. Each name is specified as a QName, which is expanded as described in [2.4 Qualified Names].

Parameters:

v - The value to set for the "use-attribute-sets" attribute.

getUseAttributeSets

public QName[] getUseAttributeSets()

Get the "use-attribute-sets" attribute. Attribute sets are used by specifying a use-attribute-sets attribute on xsl:element, xsl:copy (see [7.5 Copying]) or xsl:attribute-set elements, or a xsl:use-attribute-sets attribute on Literal Result Elements. The value of the use-attribute-sets attribute is a whitespace-separated list of names of attribute sets. Each name is specified as a QName, which is expanded as described in [2.4 Qualified Names].

Returns:

The value of the "use-attribute-sets" attribute.

applyAttrSets

public void applyAttrSets(TransformerImpl transformer,
                          StylesheetRoot stylesheet)
                   throws javax.xml.transform.TransformerException

Add the attributes from the named attribute sets to the attribute list. TODO: Error handling for: "It is an error if there are two attribute sets with the same expanded-name and with equal import precedence and that both contain the same attribute unless there is a definition of the attribute set with higher import precedence that also contains the attribute."

Parameters:

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

stylesheet - The owning root stylesheet

Throws:

javax.xml.transform.TransformerException

applyAttrSets

private void applyAttrSets(TransformerImpl transformer,
                           StylesheetRoot stylesheet,
                           QName[] attributeSetsNames)
                    throws javax.xml.transform.TransformerException

Add the attributes from the named attribute sets to the attribute list. TODO: Error handling for: "It is an error if there are two attribute sets with the same expanded-name and with equal import precedence and that both contain the same attribute unless there is a definition of the attribute set with higher import precedence that also contains the attribute."

Parameters:

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

stylesheet - The owning root stylesheet

attributeSetsNames - List of attribute sets names to apply

Throws:

javax.xml.transform.TransformerException

execute

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

Copy attributes specified by use-attribute-sets to the result tree. Specifying a use-attribute-sets attribute is equivalent to adding xsl:attribute elements for each of the attributes in each of the named attribute sets to the beginning of the content of the element with the use-attribute-sets attribute, in the same order in which the names of the attribute sets are specified in the use-attribute-sets attribute. It is an error if use of use-attribute-sets attributes on xsl:attribute-set elements causes an attribute set to directly or indirectly use itself.

Overrides:

execute in class ElemTemplateElement

Parameters:

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

Throws:

javax.xml.transform.TransformerException
