OpenCOM
Class MetaInterface

java.lang.Object
  OpenCOM.MetaInterface

public class MetaInterface
extends java.lang.Object

Each OpenCOM component contains this object to implement the interface meta-model. Methods for introspecting interfaces, and receptacles are available. Furthermore, meta-data can be attached and read as name-value pairs from both the interfaces and the receptacles.

public MetaInterface(IOpenCOM pRTintf,
                     IUnknown component)

Creates a new instance of MetaInterface

Method Detail

GetInterfaces

public void GetInterfaces(java.lang.Class c,
                          java.util.Vector<java.lang.Class> a)

Get the interfaces (as Java classes) of a component and stores them in the given vector. The operation is recursive to find inherited interfaces.

Parameters:

compClass - The class of the component.

intfList - The Vector to be filled with the components interfaces.

ReadInterfaceNames

public void ReadInterfaceNames(java.lang.Class c,
                               java.util.Vector<java.lang.String> a)

enumIntfs

public int enumIntfs(java.lang.Object o,
                     java.util.Vector<java.lang.Class> ppIntf)

Get the interfaces (as Java classes) of a component and stores them in the given vector.

Parameters:

compRef - The reference to the instance of the component.

intfList - The Vector to be filled with the components interfaces.

Returns:

An integer describing the number of interfaces on this component.

enumRecps

public int enumRecps(IUnknown comp,
                     java.util.Vector<OCM_RecpMetaInfo_t> ppRecpMetaInfo)

Get the receptacles of a component and stores them in the given vector.

Parameters:

compRef - The reference to the instance of the component.

intfList - The Vector to be filled with the component's receptacles.

Returns:

An integer describing the number of receptacles on this component.

                                 java.lang.Object Value)

Set the value of a name value pair on either an interface or receptacle.

Parameters:

pIUnk - The reference to the instance of the component the interface or receptacle is hosted on.

Runtime - Reference to the OpenCOM runtime interface.

iid - The type of the interface or receptacle.

Kind - A string which is either "Interface" or "Receptacle".

Name - A string describing the attribute name.

Type - A string describing the attribute type.

Value - An object holding the attribute value.

Returns:

A boolean indicating if the attribute value was added.

GetAttributeValue

public TypedAttribute GetAttributeValue(java.lang.String iid,

                                        java.lang.String Name)

Retrieve the value of a name value pair on either an interface or receptacle.

Parameters:

pIUnk - The reference to the instance of the component the interface or receptacle is hosted on.

Runtime - Reference to the OpenCOM runtime interface.

iid - The type of the interface or receptacle.

Kind - A string which is either "Interface" or "Receptacle".

Name - A string describing the attribute name.

Returns:

An object holding the value of the attribute.

GetAllValues

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

Retrieve all the name value pairs on either an interface or receptacle.

Parameters:

pIUnk - The reference to the instance of the component the interface or receptacle is hosted on.

iid - The type of the interface or receptacle.

Kind - A string which is either "Interface" or "Receptacle".

Returns:
