Constructor Detail

XSLForEachGroup

public XSLForEachGroup()
Method Detail

isInstruction

public boolean isInstruction()
Determine whether this node is an instruction.

Overrides:
isInstruction in class StyleElement
Returns:
true - it is an instruction

mayContainSequenceConstructor

public boolean mayContainSequenceConstructor()
Determine whether this type of element is allowed to contain a template-body

Overrides:
mayContainSequenceConstructor in class StyleElement
Returns:
true: yes, it may contain a template-body

prepareAttributes

public void prepareAttributes()
                       throws javax.xml.transform.TransformerConfigurationException
Description copied from class: StyleElement
Set the attribute list for the element. This is called to process the attributes (note the distinction from processAttributes in the superclass). Must be supplied in a subclass

Specified by:
prepareAttributes in class StyleElement
javax.xml.transform.TransformerConfigurationException

validate

public void validate()
              throws javax.xml.transform.TransformerConfigurationException
Description copied from class: StyleElement
Check that the stylesheet element is valid. This is called once for each element, after the entire tree has been built. As well as validation, it can perform first-time initialisation. The default implementation does nothing; it is normally overriden in subclasses.

Overrides:
validate in class StyleElement
javax.xml.transform.TransformerConfigurationException

getContextItemType

public ItemType getContextItemType()
Get the type of the context item within this instruction

Overrides:
getContextItemType in class StyleElement
Returns:
the static type of the context item, or Type.EMPTY if it is known that there will be no context item

compile

public Instruction compile(Executable exec)
                    throws javax.xml.transform.TransformerConfigurationException
Description copied from class: StyleElement
Compile the instruction on the stylesheet tree into an executable instruction for use at run-time.

Specified by:
compile in class StyleElement
Returns:
either an Instruction, or null. The value null is returned when compiling an instruction that returns a no-op, or when compiling a top-level object such as an xsl:template that compiles into something other than an instruction.
javax.xml.transform.TransformerConfigurationException
