Direct Known Subclasses:

ExternalAttributeExp, OccurrenceExp

public class OtherExp
extends Expression

Base class for application-specific AGM annotation.

This primitive has no meaning to MSV. For example, the following expression

 Expression exp = new OtherExp( pool.createSequence(a,b) );
 

is treated as if MSV sees the following, OtherExp-less expression:

 Expression exp = pool.createSequence(a,b);
 

By using this "transparency", application can implement derived classes of OtherExp and add application-specific information to AGM.

For example, you can implement AnnotationInfoExp class that derives OtherExp and introduces "documentation" field. Then you'll write a customized XMLSchemaReader that parses <annotation> tag and mix AnnotationInfoExp into an AGM. Your application can then examine it and do some useful things.

Those application-specific information added through OtherExp are completely ignored by MSV. So the annotated AGM can still be used just like anormal AGM.

returns the string which will be used by ExpressionPrinter to print this expression.

calcHashCode

protected final int calcHashCode()

Description copied from class: Expression

Computes the hashCode again.

This method and the parameter to the constructor has to be the same. This method is used when the object is being read from the stream.

Specified by:
