All Implemented Interfaces:

Receiver, javax.xml.transform.Result

public class ValidationStack

extends ProxyReceiver

implements Receiver

This class manages the receivers that do element content validation. It maintains a stack of Validators, each of which does local element validation of the contents of a single element, adding a new validator to the stack to handle each layer of nesting.

Constructor Detail

ValidationStack

public ValidationStack(Receiver out,
                       int initialValidationMode)

setDocumentLocator

public void setDocumentLocator(org.xml.sax.Locator locator)
                        throws javax.xml.transform.TransformerException

Set the Document Locator

Specified by:

setDocumentLocator in interface Receiver

Overrides:

setDocumentLocator in class ProxyReceiver

javax.xml.transform.TransformerException

setConstraintChecker

public void setConstraintChecker(ConstraintChecker checker)

Set the constraint checker in use (if any). The ValidationStack is responsible for telling the constraint checker about the ElementDeclaration that defines the uniqueness constraints for the current element. This is done immediately after the startElement call.

setXSIType

public void setXSIType(SchemaType type)

Set the value of xsi:type, if present. This will be called immediately before the startElement call for the element on which the xsi:type attribute appears.

setNamespaceResolver

public void setNamespaceResolver(NamespaceResolver resolver)

Set the NamespaceResolver to be used for resolving QName-valued attributes

startElement

public void startElement(int nameCode,
                         int typeCode,
                         int properties)
                  throws javax.xml.transform.TransformerException

Output element start tag

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ProxyReceiver

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.

javax.xml.transform.TransformerException

setInitialValidator

public void setInitialValidator(Validator validator)

Set the initial validator to be used for the outermost element

attribute

public void attribute(int nameCode,
                      int typeCode,
                      java.lang.CharSequence value,
                      int properties)
               throws javax.xml.transform.TransformerException

Handle an attribute

Specified by:

attribute in interface Receiver

Overrides:

attribute in class ProxyReceiver

Parameters:

nameCode - integer identifying the name of the attribute

typeCode - integer identifying the type annotation (ignored)

value - the value of the attribute

properties - additional properties of the attribute

Throws:

javax.xml.transform.TransformerException - On any failure to write the attribute

startContent

public final void startContent()
                        throws javax.xml.transform.TransformerException

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 interface Receiver

Overrides:

startContent in class ProxyReceiver

javax.xml.transform.TransformerException

characters

public void characters(java.lang.CharSequence chars,
                       int properties)
                throws javax.xml.transform.TransformerException

Description copied from interface: Receiver

Notify 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:

characters in interface Receiver

Overrides:

characters in class ProxyReceiver

Parameters:

chars - The characters

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

javax.xml.transform.TransformerException

endElement

public void endElement()
                throws javax.xml.transform.TransformerException

End of element

Specified by:

endElement in interface Receiver

Overrides:

endElement in class ProxyReceiver

javax.xml.transform.TransformerException
