setSystemId
Description copied from interface:Receiver
Set the System ID of the tree represented by this event stream- Specified by:
setSystemId
in interfaceReceiver
- Specified by:
setSystemId
in interfaceResult
-
getSystemId
- Specified by:
getSystemId
in interfaceResult
-
setPipelineConfiguration
Set the pipeline configuration- Specified by:
setPipelineConfiguration
in interfaceReceiver
-
getPipelineConfiguration
Get the pipeline configuration- Specified by:
getPipelineConfiguration
in interfaceReceiver
-
open
Start of event stream- Specified by:
open
in interfaceReceiver
- Throws:
XPathException
-
close
End of event stream- Specified by:
close
in interfaceReceiver
- Throws:
XPathException
-
startDocument
Start of a document node.- Specified by:
startDocument
in interfaceReceiver
- Throws:
XPathException
-
endDocument
Notify the end of a document node- Specified by:
endDocument
in interfaceReceiver
- Throws:
XPathException
-
startElement
public void startElement(int nameCode, int typeCode, int locationId, int properties) throws XPathException Notify the start of an element- Specified by:
startElement
in interfaceReceiver
- 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.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
- for future use. Should be set to zero.- 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.- Specified by:
namespace
in interfaceReceiver
- 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.- Specified by:
attribute
in interfaceReceiver
- Parameters:
nameCode
- The name of the attribute, as held in the name pooltypeCode
- The type of the attribute, as held in the name poollocationId
- 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.- Specified by:
startContent
in interfaceReceiver
- Throws:
XPathException
-
endElement
End of element- Specified by:
endElement
in interfaceReceiver
- Throws:
XPathException
-
characters
Character data- Specified by:
characters
in interfaceReceiver
- 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
public void processingInstruction(String target, CharSequence data, int locationId, int properties) throws XPathException Processing Instruction- Specified by:
processingInstruction
in interfaceReceiver
- 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- Specified by:
comment
in interfaceReceiver
- 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
-
setUnparsedEntity
Set the URI for an unparsed entity in the document.- Specified by:
setUnparsedEntity
in interfaceReceiver
- Parameters:
name
