public interface IMetaInterface

This interface is implemented by every OpenCOM component. It support the interface meta-model of OpenCOM. Allow instrospection and manipualtion of interfaces and receptacles on the component plus the corresponding meta-data attachments.

Method Summary

int	enumIntfs(java.util.Vector<java.lang.Class> ppIntf) Returns a Vector of meta-information.
int	enumRecps(java.util.Vector<OCM_RecpMetaInfo_t> ppRecpMetaInfo) Returns a Vector of meta-information.
java.util.Hashtable	GetAllValues(java.lang.String Kind, java.lang.String iid) This method retrieves all the meta-data stored on the interface or receptacle.
TypedAttribute	GetAttributeValue(java.lang.String iid, java.lang.String Kind, java.lang.String Name) Meta-data can be retrieved from each interface/receptacle of a component.
boolean	SetAttributeValue(java.lang.String iid, java.lang.String Kind, java.lang.String Name, java.lang.String Type, java.lang.Object Value) Meta-data can be attached to each interface/receptacle of a component.

Method Detail

enumRecps

int enumRecps(java.util.Vector<OCM_RecpMetaInfo_t> ppRecpMetaInfo)

Returns a Vector of meta-information. Each elements of the Vector is an object of type OCM_RecpMetaInfo_t, which describes the attributes of indiviudal receptacles including: type (single or multiple) & interface type.

Parameters:

ppRecpMetaInfo - a Vector to be filled with receptacle meta-information.

Returns:

an Integer describing the number of receptacles on the component.

enumIntfs

int enumIntfs(java.util.Vector<java.lang.Class> ppIntf)

Returns a Vector of meta-information. Each elements of the Vector is a String describing that interface's type.

Parameters:

ppRecpMetaInfo - a Vector to be filled with interface meta-information.

Returns:

an Integer describing the number of interfaces on the component.

SetAttributeValue

boolean SetAttributeValue(java.lang.String iid,
                          java.lang.String Kind,
                          java.lang.String Name,
                          java.lang.String Type,
                          java.lang.Object Value)

Meta-data can be attached to each interface/receptacle of a component. This method adds a name value pair to a given interface or receptacle instance.

Parameters:

iid - the type of the interface or receptacle.

Kind - a string saying whether to attach to an interface or a receptacle.

Name - A String describing the attribute name.

Type - A String describing the attribute type.

Value - An object representing the attribute value.

Returns:

A boolean indicating the success of the operation.

GetAttributeValue

TypedAttribute GetAttributeValue(java.lang.String iid,
                                 java.lang.String Kind,
                                 java.lang.String Name)

Meta-data can be retrieved from each interface/receptacle of a component. This method retrieves the value of a name attribute on a receptacle or interface.

Parameters:

iid - the type of the interface or receptacle.

Kind - a string saying whether to attach to an interface or a receptacle.

Name - A String describing the attribute name.

Returns:

A TypedAttribute object containing the value and type of the meta-data attribute.

GetAllValues

java.util.Hashtable GetAllValues(java.lang.String Kind,
                                 java.lang.String iid)

This method retrieves all the meta-data stored on the interface or receptacle.

Parameters:

iid - the type of the interface or receptacle.

Kind - a string saying whether to attach to an interface or a receptacle.

Returns:

A hashatable containing all of the attribute-value pairs for the receptacle or interface.
