ICMIAbstractInfo

public interface ICMIRelationRoleInfo

extends ICMIAbstractInfo

represents the metadats of a model relation role at runtime This type can be called, extended or implemented by applications or frameworks using CMI.

Method Summary

CMICardinality	getCardinality() returns the cardinality of the role according the defined CARDINALITY...
ICMIModelClassInfo	getModelClassInfo() returns the model class info of the model class, to which the role belongs
ICMIRelationInfo	getModelRelationInfo() returns the corresponing relation info or null, if this method is not supported.
ICMIRelationRoleInfo	getOtherRoleInfo() returns the other role.
boolean	isAggregation() returns true, if role is a aggregating role
boolean	isNavigable() returns true, if role is navigable

Method Detail

getModelClassInfo

public ICMIModelClassInfo getModelClassInfo()

returns the model class info of the model class, to which the role belongs

getOtherRoleInfo

public ICMIRelationRoleInfo getOtherRoleInfo()

returns the other role. If this is the source role info, the target role info is returned and vice versa. An implementation can derive this information from the corresponding relation info or from a source role : target role association.

getModelRelationInfo

public ICMIRelationInfo getModelRelationInfo()

returns the corresponing relation info or null, if this method is not supported. So model implementations, which have difficulties to supply relation info,can implement this method with return null;

getCardinality

public CMICardinality getCardinality()

returns the cardinality of the role according the defined CARDINALITY... constants.
