Method Details
-
open
Start of event stream- Specified by:
open
in interfaceReceiver
- Overrides:
open
in classSequenceReceiver
- Throws:
XPathException
-
close
End of event stream- Throws:
XPathException
-
startDocument
Start of a document node.- Parameters:
properties
- bit-significant integer indicating properties of the document node. The definitions of the bits are in classReceiverOptions
- Throws:
XPathException
-
endDocument
Notify the end of a document node- Throws:
XPathException
-
startElement
public void startElement(int nameCode, int typeCode, int locationId, int properties) throws XPathException 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.properties
- for future use. Should be set to zero.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.- 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; however, duplicates may be reported. 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 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 poolproperties
- 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 attributelocationId
- 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.- 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
End of element- Throws:
XPathException
-
characters
Character data- 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
- Throws:
XPathException
-
processingInstruction
public void processingInstruction(String target, CharSequence data, int locationId, int properties) throws XPathException 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 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
Output a comment- Parameters:
chars
- 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
-
append
Append an arbitrary item (node or atomic value) to the output- Specified by:
append
in classSequenceReceiver
- Parameters:
item
- the item to be appendedlocationId
- the location of the calling instruction, for diagnosticscopyNamespaces
- if the item is an element node, this indicates whether its namespaces need to be copied. Values areNodeInfo.ALL_NAMESPACES
,NodeInfo.LOCAL_NAMESPACES
,NodeInfo.NO_NAMESPACES
- Throws:
XPathException
-
setUnparsedEntity
Set the URI for an unparsed entity in the document.- Specified by:
setUnparsedEntity
in interfaceReceiver
- Overrides:
setUnparsedEntity
in classSequenceReceiver
- Parameters:
name
- The name of the unparsed entityuri
- The system identifier of the unparsed entitypublicId
- The public identifier of the unparsed entity- Throws:
XPathException
