public interface XMLDTDContentModelHandler

The DTD content model handler interface defines callback methods to report information items in DTD content models of an element declaration. Parser components interested in DTD content model information implement this interface and are registered as the DTD content model handler on the DTD content model source.

Field Detail

SEPARATOR_CHOICE

public static final short SEPARATOR_CHOICE

A choice separator for children and mixed content models. This separator is used to specify that the allowed child is one of a collection.

For example:

 <!ELEMENT elem (foo|bar)>
 <!ELEMENT elem (foo|bar+)>
 <!ELEMENT elem (foo|bar|baz)>
 <!ELEMENT elem (#PCDATA|foo|bar)*>
 

See Also:

SEPARATOR_SEQUENCE

SEPARATOR_SEQUENCE

public static final short SEPARATOR_SEQUENCE

A sequence separator for children content models. This separator is used to specify that the allowed children must follow in the specified sequence.

 <!ELEMENT elem (foo,bar)>
 <!ELEMENT elem (foo,bar*)>
 <!ELEMENT elem (foo,bar,baz)>
 

See Also:

SEPARATOR_CHOICE

OCCURS_ZERO_OR_ONE

public static final short OCCURS_ZERO_OR_ONE

This occurrence count limits the element, choice, or sequence in a children content model to zero or one. In other words, the child is optional.

For example:

 <!ELEMENT elem (foo?)>
 

See Also:

OCCURS_ZERO_OR_MORE, OCCURS_ONE_OR_MORE

OCCURS_ZERO_OR_MORE

public static final short OCCURS_ZERO_OR_MORE

This occurrence count limits the element, choice, or sequence in a children content model to zero or more. In other words, the child may appear an arbitrary number of times, or not at all. This occurrence count is also used for mixed content models.

For example:

 <!ELEMENT elem (foo*)>
 <!ELEMENT elem (#PCDATA|foo|bar)*>
 

See Also:

OCCURS_ZERO_OR_ONE, OCCURS_ONE_OR_MORE

OCCURS_ONE_OR_MORE

public static final short OCCURS_ONE_OR_MORE

This occurrence count limits the element, choice, or sequence in a children content model to one or more. In other words, the child may appear an arbitrary number of times, but must appear at least once.

For example:

 <!ELEMENT elem (foo+)>

OCCURS_ZERO_OR_ONE, OCCURS_ZERO_OR_MORE

Method Detail

startContentModel

public void startContentModel(java.lang.String elementName,
                              Augmentations augmentations)
                       throws XNIException

Parameters:

elementName - The name of the element.

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by handler to signal an error.

any

public void any(Augmentations augmentations)
         throws XNIException

A content model of ANY.

Parameters:

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by handler to signal an error.

Parameters:

augmentations - Additional information that may include infoset augmentations.

Throws:

XNIException - Thrown by handler to signal an error.
