systemID - The system identifier of the unparsed entity
publicID - The public identifier of the unparsed entity
Throws:
XPathException

open

public void open()
Start of the document.

Specified by:
open in interface Receiver
Overrides:
open in class Builder

close

public void close()
End of the document.

Specified by:
close in interface Receiver
Overrides:
close in class Builder

startDocument

public void startDocument(int properties)
                   throws XPathException
Start of a document node.

Parameters:
properties - bit-significant integer indicating properties of the document node. The definitions of the bits are in class ReceiverOptions
Throws:
XPathException

endDocument

public void endDocument()
                 throws XPathException
Notify the end of a document node

Throws:
XPathException

startElement

public void startElement(int nameCode,
                         int typeCode,
                         int locationId,
                         int properties)
                  throws XPathException
Start of an element.

Parameters:
nameCode - integer code identifying the name of the element within the name pool.
typeCode - integer code identifying the element's type within the name pool. The value -1 indicates the default type, xs:untyped.
locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.
properties - bit-significant properties of the element node. If there are no revelant properties, zero is supplied. The definitions of the bits are in class ReceiverOptions
Throws:
XPathException

namespace

public void namespace(int namespaceCode,
                      int properties)
               throws XPathException
Description copied from interface: Receiver
Notify a namespace. Namespaces are notified after the startElement event, and before any children for the element. The namespaces that are reported are only required to include those that are different from the parent element. The events represent namespace declarations and undeclarations rather than in-scope namespace nodes: an undeclaration is represented by a namespace code of zero. If the sequence of namespace events contains two A namespace must not conflict with any namespaces already used for element or attribute names.

Parameters:
namespaceCode - an integer: the top half is a prefix code, the bottom half a URI code. These may be translated into an actual prefix and URI using the name pool. A prefix code of zero represents the empty prefix (that is, the default namespace). A URI code of zero represents a URI of "", that is, a namespace undeclaration.
properties - The most important property is REJECT_DUPLICATES. If this property is set, the namespace declaration will be rejected if it conflicts with a previous declaration of the same prefix. If the property is not set, the namespace declaration will be ignored if it conflicts with a previous declaration. This reflects the fact that when copying a tree, namespaces for child elements are emitted before the namespaces of their parent element. Unfortunately this conflicts with the XSLT rule for complex content construction, where the recovery action in the event of conflicts is to take the namespace that comes last. XSLT therefore doesn't recover from this error: it sets the REJECT_DUPLICATES flag, and this is treated as a hard error.
Throws:
XPathException

attribute

public void attribute(int nameCode,
                      int typeCode,
                      CharSequence value,
                      int locationId,
                      int properties)
               throws XPathException
Description copied from interface: Receiver
Notify an attribute. Attributes are notified after the startElement event, and before any children. Namespaces and attributes may be intermingled.

Parameters:
nameCode - The name of the attribute, as held in the name pool
typeCode - The type of the attribute, as held in the name pool. The additional bit NodeInfo.IS_DTD_TYPE may be set to indicate a DTD-derived type.
value - the string value of the attribute
locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.
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
Throws:
XPathException

startContent

public void startContent()
                  throws XPathException
Description copied from interface: Receiver
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.

Throws:
XPathException

endElement

public void endElement()
                throws XPathException
End of an element.

Throws:
XPathException

characters

public void characters(CharSequence chars,
                       int locationId,
                       int properties)
                throws XPathException
Character data.

Parameters:
chars - The characters
locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.
properties - Bit significant value. The following bits are defined:
DISABLE_ESCAPING
Disable escaping for this text node
USE_CDATA
Output as a CDATA section
Throws:
XPathException

processingInstruction

public void processingInstruction(String target,
                                  CharSequence data,
                                  int locationId,
                                  int properties)
                           throws XPathException
Handle a processing instruction.

Parameters:
target - The PI name. This must be a legal name (it will not be checked).
data - The data portion of the processing instruction
locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.
properties - Additional information about the PI. The following bits are defined:
CHECKED
Data is known to be legal (e.g. doesn't contain "?>")
Throws:
XPathException

comment

public void comment(CharSequence chars,
                    int locationId,
                    int properties)
             throws XPathException
Handle a comment.

Parameters:
chars - The content of the comment
locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.
properties - Additional information about the comment. The following bits are defined:
CHECKED
Comment is known to be legal (e.g. doesn't contain "--")
Throws:
XPathException

usesTypeAnnotations

public boolean usesTypeAnnotations()
Ask whether this Receiver (or the downstream pipeline) makes any use of the type annotations supplied on element and attribute events

Specified by:
usesTypeAnnotations in interface Receiver
Overrides:
usesTypeAnnotations in class Builder
Returns:
true if the Receiver makes any use of this information. If false, the caller may supply untyped nodes instead of supplying the type annotation

getDocument

public org.dom4j.Document getDocument()
Get the constructed document node

Returns:
the document node of the constructed XOM tree

getCurrentRoot

public NodeInfo getCurrentRoot()
Get the current root node.

Overrides:
