setSystemId
public void setSystemId(java.lang.String systemId)
Description copied from class:SequenceReceiverSet the system ID- Specified by:
setSystemIdin interfaceReceiver- Specified by:
setSystemIdin interfacejavax.xml.transform.Result- Overrides:
setSystemIdin classSequenceReceiver- Parameters:
systemId- the URI used to identify the tree being passed across this interface
-
setUnderlyingReceiver
public void setUnderlyingReceiver(Receiver receiver)
Set the underlying receiver. This call is mandatory before using the Receiver.- Parameters:
receiver- the underlying receiver, the one that is to receive events after processing by this filter.
-
getNextReceiver
public Receiver getNextReceiver()
Get the next Receiver in the pipeline- Returns:
- the next Receiver in the pipeline
-
setPipelineConfiguration
public void setPipelineConfiguration(PipelineConfiguration pipe)
Description copied from interface:ReceiverSet the pipeline configuration- Specified by:
setPipelineConfigurationin interfaceReceiver- Overrides:
setPipelineConfigurationin classSequenceReceiver- Parameters:
pipe- the pipeline configuration
-
getNamePool
public NamePool getNamePool()
Get the namepool for this configuration- Overrides:
getNamePoolin classSequenceReceiver- Returns:
- the Name Pool that was supplied using the setConfiguration() method
-
open
public void open() throws XPathExceptionStart of event stream- Specified by:
openin interfaceReceiver- Overrides:
openin classSequenceReceiver- Throws:
XPathException- if an error occurs
-
close
public void close() throws XPathExceptionEnd of output. Note that closing this receiver also closes the rest of the pipeline.- Throws:
XPathException- if an error occurs
-
startDocument
public void startDocument(int properties) throws XPathExceptionStart of a document node.- Parameters:
properties- bit-significant integer indicating properties of the document node. The definitions of the bits are in classReceiverOption- Throws:
XPathException- if an error occurs
-
endDocument
public void endDocument() throws XPathExceptionNotify the end of a document node- Throws:
XPathException- if an error occurs
-
startElement
public void startElement(NodeName elemName, SchemaType type, AttributeMap attributes, NamespaceMap namespaces, Location location, int properties) throws XPathException
Notify the start of an element- Parameters:
elemName- the name of the element.type- the type annotation of the element.attributes- the attributes of this elementnamespaces- the in-scope namespaces of this element: generally this is all the in-scope namespaces, without relying on inheriting namespaces from parent elementslocation- an object providing information about the module, line, and column where the node originatedproperties- bit-significant properties of the element node. If there are no relevant properties, zero is supplied. The definitions of the bits are in classReceiverOption- Throws:
XPathException- if an error occurs
-
endElement
public void endElement() throws XPathExceptionEnd of element- Throws:
XPathException- if an error occurs
-
characters
public void characters(java.lang.CharSequence chars, Location locationId, int properties) throws XPathExceptionCharacter data- Parameters:
chars- The characterslocationId- provides information such as line number and system ID.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, Location locationId, int properties) throws XPathExceptionProcessing 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- provides information such as line number and system ID.properties- Additional information about the PI.- Throws:
XPathException- if an error occurs
-
comment
public void comment(java.lang.CharSequence chars, Location locationId, int properties) throws XPathExceptionOutput a comment- Parameters:
chars- The content of the commentlocationId- provides information such as line number and system ID.properties- Additional information about the comment.- Throws:
XPathException- if an error occurs
-
setUnparsedEntity
public void setUnparsedEntity(java.lang.String name, java.lang.String uri, java.lang.String publicId) throws XPathExceptionSet the URI for an unparsed entity in the document.- Specified by:
setUnparsedEntityin interfaceReceiver- Overrides:
setUnparsedEntityin 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
-
append
public void append(Item item, Location locationId, int properties) throws XPathException
Append an arbitrary item (node or atomic value) to the output- Specified by:
appendin interfaceReceiver- Specified by:
appendin classSequenceReceiver- Parameters:
item- the item to be appendedlocationId- the location of the calling instruction, for diagnosticsproperties- if the item is an element node, this indicates whether its namespaces need to be copied. Values areReceiverOption.ALL_NAMESPACES; the default (0) means- 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
