action
public abstract void action() throws XPathException- Throws:
XPathException
-
startDocument
public void startDocument(int properties) throws XPathExceptionDescription copied from class:ProxyOutputterNotify the start of a document node- Specified by:
startDocumentin interfaceReceiver- Overrides:
startDocumentin classProxyOutputter- 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 XPathExceptionDescription copied from class:ProxyOutputterNotify the end of a document node- Specified by:
endDocumentin interfaceReceiver- Overrides:
endDocumentin classProxyOutputter- Throws:
XPathException- if an error occurs
-
startElement
public void startElement(NodeName elemName, SchemaType typeCode, Location location, int properties) throws XPathException
Description copied from class:ProxyOutputterNotify the start of an element- Overrides:
startElementin classProxyOutputter- Parameters:
elemName- the name of the element.typeCode- the type annotation of the element.location- 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
-
startElement
public void startElement(NodeName elemName, SchemaType type, AttributeMap attributes, NamespaceMap namespaces, Location location, int properties) throws XPathException
Description copied from class:ProxyOutputterNotify the start of an element, supplying all attributes and namespaces- Specified by:
startElementin interfaceReceiver- Overrides:
startElementin classProxyOutputter- 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
-
namespace
public void namespace(java.lang.String prefix, java.lang.String namespaceUri, int properties) throws XPathExceptionDescription copied from class:ProxyOutputterNotify a namespace binding. This method is called at some point after startElement(). The semantics are similar to the xsl:namespace instruction in XSLT, or the namespace node constructor in XQuery. A namespace must not conflict with any namespaces already used for element or attribute names.- Overrides:
namespacein classProxyOutputter- Parameters:
prefix- The namespace prefix; zero-length string for the default namespacenamespaceUri- The namespace URI. In some cases a zero-length string may be used to indicate a namespace undeclaration.properties- The REJECT_DUPLICATES property: if 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
-
endElement
public void endElement() throws XPathExceptionDescription copied from class:ProxyOutputterNotify the end of an element. The Outputter must maintain a stack if it needs to know which element is ending.- Specified by:
endElementin interfaceReceiver- Overrides:
endElementin classProxyOutputter- Throws:
XPathException- if an error occurs
-
characters
public void characters(java.lang.CharSequence chars, Location location, int properties) throws XPathExceptionDescription copied from class:ProxyOutputterNotify 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.- Specified by:
charactersin interfaceReceiver- Overrides:
charactersin classProxyOutputter- Parameters:
chars- The characterslocation- 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
-
comment
public void comment(java.lang.CharSequence content, Location location, int properties) throws XPathExceptionDescription copied from class:ProxyOutputterNotify a comment. Comments are only notified if they are outside the DTD.- Specified by:
commentin interfaceReceiver- Overrides:
commentin classProxyOutputter- Parameters:
content- The content of the commentlocation- provides information such as line number and system ID.properties- Additional information about the comment.- Throws:
XPathException- if an error occurs
-
attribute
public void attribute(NodeName attName, SimpleType typeCode, java.lang.CharSequence value, Location location, int properties) throws XPathException
Description copied from class:ProxyOutputterNotify an attribute. Attributes are notified after the startElement event, and before any children. Namespaces and attributes may be intermingled.- Overrides:
attributein classProxyOutputter- Parameters:
attName- The name of the attributetypeCode- The type annotation of the attributevalue- the string value of the attributelocation- provides information such as line number and system ID.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- if an error occurs
-
append
public void append(Item item) throws XPathException
Description copied from class:ItemFeedSupply one item towards the streamed input of the expression- Specified by:
appendin interfaceReceiver- Specified by:
appendin classItemFeed- Parameters:
item- the item to be supplied- Throws:
XPathException- if the operation fails
-
close
public abstract void close() throws XPathExceptionDescription copied from class:ItemFeedFinish evaluating the expression.- Specified by:
closein interfaceReceiver- Overrides:
closein classItemFeed- Throws:
XPathException- if a dynamic error occurs
