Method Details

addChild

public void addChild(String attributeName,
 IInstanceDS childDS)

Description copied from interface: IValueVisitor

This method can be used to add an anonymous child instance. To add a reference to another static instance use the addRelation method instead.

Specified by:

addChild in interface IValueVisitor

Parameters:

attributeName - The name of the attribute to which the child instance definition should be added.

childDS - The data source that provides the information for the child instance.

addRelation

public void addRelation(String attributeName,
 String entityType,
 String instanceName)

Description copied from interface: IValueVisitor

This method can be invoked to link the attribute to another static instance. Both the name and the type of the static instance should be provided, as the name of an instance needs only be unique amongst the other instances of that type.

Specified by:

addRelation in interface IValueVisitor

Parameters:

attributeName - The name of the attribute to which the child instance definition should be added.

entityType - The type of the instance the relation should refer to.

instanceName - The name of the instance the relation should refer to.

setValue

public void setValue(String attributeName,
 IValue objValue)

Description copied from interface: IValueVisitor

When a setValue is invoked for a relation attribute, the value should be either the name or the ID of the (static) instance that should be referenced.

Specified by:

setValue in interface IValueVisitor

Parameters:

attributeName - The name of the attribute of which the value should be set.

objValue - The value for the attribute.
