MATLAB^® Builder™ EX

componentinfo - Query system registry about component created with MATLAB Builder EX

Syntax

info = componentinfo info = componentinfo(component_name) info = componentinfo(component_name, major_revision_number) info = componentinfo(component_name, major_revision_number, minor_revision_number)

Arguments

`component_name`	The MATLAB string providing the name of a MATLAB Builder EX component. Names are case sensitive. If this argument is not supplied, the function returns information on all installed components.
`major_revision_number`	Component major revision number. If this argument is not supplied, the function returns information on all major revisions.
`minor_revision_number`	Component minor revision number. Default value is `0`.

Description

info = componentinfo returns information for all components installed on the system.

info = componentinfo(component_name) returns information for all revisions of component_name.

info = componentinfo(component_name, major_revision_number) returns information for the most recent minor revision corresponding to major_revision_number of component_name.

info = componentinfo(component_name, major_revision_number, minor_revision_number) returns information for the specific major and minor version of component_name.

The return value is an array of structures representing all the registry and type information needed to load and use the component.

When you supply a component name, major_revision_number and minor_revision_number are interpreted as shown below.

Value	Information Returned
> `0`	Information on a specific major and minor revision
`0`	Information on the most recent revision. When omitted, `minor_revision_number` is assumed to be equal to `0`.
`< 0`	Information on all versions

Note Although properties and events may appear in the output for componentinfo, they are not supported by builder components.

Registry Information

The information about a component has the fields shown in the following table.

Registry Information Returned by componentinfo

Field	Description
`Name`	Component name.
`TypeLib`	Component type library.
`LIBID`	Component type library GUID.
`MajorRev`	Major version number .
`MinorRev`	Minor version number.
`FileName`	Type library file name and path. Since all the MATLAB Builder EX components have the type library bound into the DLL, this file name is the same as the DLL name and path.
`Interfaces`	An array of structures defining all interface definitions in the type library. Each structure contains two fields: `Name` - Interface name. `IID` - Interface GUID.
`CoClasses`	An array of structures defining all COM classes in the component. Each structure contains these fields: Name - Class name. CLSID - GUID of the class. ProgID - Version-dependent program ID. VerIndProgID - Version-independent program ID. InprocServer32 - Full name and path to component DLL. Methods - A structure containing function prototypes of all class methods defined for this interface. This structure contains four fields: IDL - An array of Interface Description Language function prototypes. M - An array of MATLAB function prototypes. C - An array of C-language function prototypes. VB - An array of VBA function prototypes. Properties - A cell array containing the names of all class properties. Events - A structure containing function prototypes of all events defined for this class. This structure contains four fields:

Examples

Function Call	Returns
`Info = componentinfo`	Information for all installed components.
`Info = componentinfo('mycomponent')`	Information for all revisions of `mycomponent`.
`Info = componentinfo('mycomponent',1,0)`	Information for revision 1.0 of `mycomponent`.
