Method Detail

open
public void open() throws XPathException
Start of event stream- Specified by:
open
in interfaceReceiver
- Overrides:
open
in classSequenceReceiver
- Throws:
XPathException
- if an error occurs
-
close
public void close() throws XPathException
End of event stream- Throws:
XPathException
- if an error occurs
-
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 classReceiverOptions
- Throws:
XPathException
- if an error occurs
-
endDocument
public void endDocument() throws XPathException
Notify the end of a document node- Throws:
XPathException
- if an error occurs
-
startElement
public void startElement(NodeName nameCode, SchemaType 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
- if an error occurs
-
namespace
public void namespace(NamespaceBinding namespaceBinding, int properties) throws XPathException
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:
namespaceBinding
- the prefix/uri pair representing the namespace binding to be writtenproperties
- 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:- Throws:
XPathException
- if an error occurs
-
attribute
public void attribute(NodeName nameCode, SimpleType typeCode, java.lang.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
- if an error occurs
-
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.- Throws:
XPathException
- if an error occurs
-
endElement
public void endElement() throws XPathException
End of element- Throws:
XPathException
- if an error occurs
-
characters
public void characters(java.lang.CharSequence chars, int locationId, int properties) throws XPathException
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
- if an error occurs
-
processingInstruction
public void processingInstruction(java.lang.String target, java.lang.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.- Throws:
XPathException
- if an error occurs
-
comment
public void comment(java.lang.CharSequence chars, int locationId, int properties) throws XPathException
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.- Throws:
XPathException
- if an error occurs
-
append
public void append(Item item, int locationId, int copyNamespaces) throws XPathException
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
- if the operation fails
-
setUnparsedEntity
public void setUnparsedEntity(java.lang.String name, java.lang.String uri, java.lang.String publicId) throws XPathException
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
- if an error occurs
-
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- 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
