Receiver: This interface represents a recipient of XML tree-walking (push) events. It is
based on SAX2's ContentHandler, but adapted to handle additional events, and
to use Saxon's name pool. Namespaces and Attributes are handled by separate events
following the startElement event. Schema types can be defined for elements and attributes.
The Receiver interface is an important internal interface within Saxon, and provides a powerful mechanism for integrating Saxon with other applications. It has been designed with extensibility and stability in mind. However, it should be considered as an interface designed primarily for internal use, and not as a completely stable part of the public Saxon API.

setUnparsedEntity
Notify an unparsed entity URI.- Parameters:
name
- The name of the unparsed entitysystemID
- The system identifier of the unparsed entitypublicID
- The public identifier of the unparsed entity- Throws:
XPathException
-
startElement
Notify the 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, xdt:untyped.locationId
- an integer which can be interpreted using aLocationProvider
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.- Throws:
XPathException
-
namespace
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
void attribute(int nameCode, int typeCode, CharSequence value, int locationId, int properties) throws XPathException 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 pooltypeCode
- 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.locationId
- an integer which can be interpreted using aLocationProvider
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
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
Notify the end of an element. The receiver must maintain a stack if it needs to know which element is ending.- Throws:
XPathException
-
characters
Notify character data. Note that some receivers may require the character data to be sent in a single event, but in general this is not a requirement.- Parameters:
chars
- The characterslocationId
- an integer which can be interpreted using aLocationProvider
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
- NO_SPECIAL_CHARACTERS
- Value contains no special characters
- WHITESPACE
- Text is all whitespace
- Throws:
XPathException
-
processingInstruction
void processingInstruction(String name, CharSequence data, int locationId, int properties) throws XPathException Output a processing instruction- Parameters:
name
- The PI name. This must be a legal name (it will not be checked).data
- The data portion of the processing instructionlocationId
- an integer which can be interpreted using aLocationProvider
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
Notify a comment. Comments are only notified if they are outside the DTD.- Parameters:
content
- The content of the commentlocationId
- an integer which can be interpreted using aLocationProvider
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
-
close
Notify the end of the event stream- Throws:
XPathException
