Method Detail

forClass

public static Domain forClass(Class cls)
                       throws DomainNotFoundException

Throws:

DomainNotFoundException

domainClass

public abstract Class domainClass()

typeIsa

public abstract boolean typeIsa(Domain other)

Tests if this Domain is assignable to the other Domain.

Parameters:

other - The domain to compare to

Returns:

true If this domain is equal to or a subtype of the other Domain.

getName

public String getName()

Gets the name of the Domain. The name is the EXPRESS symbol, converted to uppercase.

Returns:

The name for the domain.

convert

public Object convert(Object obj)

Try to convert an object to a corresponding object of this type. Note that this is not a typecast method, instead, it is intended to provide a fallback to convert objects of the wrong type to the correct one. (This could be used, for example, after Attribute.setValue() throws a TypeException.)

Parameters:

obj - The object to convert.

Returns:

The other object converted to one of this domain. If the conversion is not possible, or not implemented, returns null.
