Constructor Detail

AttributeSorter

public AttributeSorter(Receiver next)

Create an attribute sorter

Parameters:

next - the next receiver in the pipeline

Method Detail

setOutputProperties

public void setOutputProperties(java.util.Properties details)

Set the properties for this attribute sorter

Parameters:

details - the output properties

startElement

public void startElement(NodeName elemName,
                         SchemaType typeCode,
                         Location location,
                         int properties)
                  throws XPathException

Notify the start of an element

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ProxyReceiver

Parameters:

elemName - integer code identifying the name of the element within the name pool.

typeCode - integer code identifying the element's type within the name pool.

location - the element's line & column number

properties - properties of the element node

Throws:

XPathException - if an error occurs

attribute

public void attribute(NodeName nameCode,
                      SimpleType typeCode,
                      java.lang.CharSequence value,
                      Location locationId,
                      int properties)

Notify an attribute. Attributes are notified after the startElement event, and before any children. Namespaces and attributes may be intermingled.

Specified by:

attribute in interface Receiver

Overrides:

attribute in class ProxyReceiver

Parameters:

nameCode - The name of the attribute

typeCode - The type of the attribute

locationId - the attribute's line & column number

properties - Bit significant value. The following bits are defined:

DISABLE_ESCAPING

Disable escaping for this attribute

NO_SPECIAL_CHARACTERS

Attribute value contains no special characters

value - the string value of the attribute

Throws:

IllegalStateException: - attempt to output an attribute when there is no open element start tag

startContent

public void startContent()
                  throws XPathException

Notify the start of the content, that is, the completion of all attributes and namespaces. Note that the initial receiver of output from XSLT instructions will not receive this event, it has to detect it itself. Note that this event is reported for every element even if it has no attributes, no namespaces, and no content.

Specified by:

startContent in interface Receiver

Overrides:

startContent in class ProxyReceiver

Throws:

XPathException - if an error occurs

compare

public int compare(int a,
                   int b)

Compare two objects within this Sortable, identified by their position.

Specified by:

compare in interface Sortable

Returns:

<0 if obj[a]<obj[b], 0 if obj[a]=obj[b], >0 if obj[a]>obj[b]

swap

public void swap(int a,
                 int b)

Swap two objects within this Sortable, identified by their position.

Specified by:

swap in interface Sortable
