Package Class

A Package object corresponds to a Package element in the Enterprise Architect Project Browser. Packages can be accessed either through the Repository Models collection (a Model is a special form of Package) or through the Package Packages collection.

Note that a Package has an Element object as an attribute; this corresponds to an Enterprise Architect Package element in the t_object table and is used to associate additional information (such as scenarios and constraints) with the logical Package.

To set additional information for a Package, reference the Element object directly. Also note that if you add a Package to a diagram, you should add an instance of the element (not the Package itself) to the DiagramObject Class for a diagram.

ReleaseUserLockRecursive ()	Boolean Notes: Releases user locks and group locks from the Package object, and all of the Packages, diagrams and elements contained within that Package. Returns True if the operation is successful; returns False if the operation is unsuccessful. Use GetLastError() to retrieve error information.
SetReadOnly (boolean ReadOnly, boolean IncludeSubPkgs)	Void Notes: Sets a Package Flag to mark a Package as ReadOnly=1. If Project Security is enabled, the user must have 'Configure Packages' permission to use this method. Throws an exception if the operation fails due to the user not having 'Configure Packages' permission; use 'GetLastError()' to retrieve error information. Parameters ReadOnly: Boolean - Sets or clears the Read Only flag on the Package(s); if: False, any Read Only flag is removed from the Package True, a Read Only flag is applied to the Package IncludeSubPkgs: Boolean - Indicates whether to set/reset the Read Only flag on just the object Package, or on the object Package and all of the nested sub-Packages that it contains; if: False, only the flag on the object Package is set or cleared True, flags are set (or cleared, according to the ReadOnly parameter) for the object Package plus all of the nested sub-Packages that it contains When working with version controlled Packages, the Read Only flag can be applied to Packages whether they are checked-in or checked-out. User Security applies to setting this flag - if you are prevented from editing the Package, you are also prevented from setting the flag.
Update ()	Boolean Notes: Updates the current Package object after modification or appending a new item. If False is returned, check the 'GetLastError()' function for more information. Note that a Package object also has an element component that must be taken into account; the Package object contains information about the Package attributes such as hierarchy or contents. The element attribute contains information about, for example, Stereotypes, Constraints or Files - all the attributes of a typical element.

Parameters Comment: String - Log message that is added to the version controlled file's history (where applicable) PreserveCrossPkgRefs: Boolean - Flag to indicate whether to preserve or discard pre-existing Cross Package References when checking-in; this parameter overrides the setting in the 'Preferences' dialog, 'XML Specifications' page Unsatisfied cross-Package references are preserved or discarded according to this setting, without prompting the user; see Learn more
VersionControlCheckout (string Comment)	Void Notes: Perform checkout of the version controlled Package. Throws an exception if the operation fails; use GetLastError() to retrieve error information. Parameters: Comment: String - Log message that is added to the version controlled file's history (where applicable) When working in an environment that uses a Private Model deployment and your model contains a significant number of cross-Package references, it is recommended that you invoke the Repository.ScanXMIAndReconcile() method from time to time, following the re-importation of controlled Packages - for example, after using Package.VersionControlGetLatest() to update a number of Packages, or after performing a number of Package check-outs.
VersionControlGetLatest (boolean ForceImport)	Void Notes: Updates the local working copy of the Package file associated with the object Package, before re-importing the Package data from the Package file. Parameters: ForceImport: Boolean - Used if the Package data in the model is found to be up-to-date with respect to the version controlled Package file; if: - False, the Package data that exists in the model is accepted as being up-to-date and no attempt is made to re-import data from the Package file - True, the system re-imports the Package from the Package file regardless See also the version control menu option 'Get Latest'. When working in an environment that uses a Private Model deployment and your model contains a significant number of cross-Package references, it is recommended that you invoke the 'Repository.ScanXMIAndReconcile()' method from time to time, following the re-importation of controlled Packages - for example, after using 'Package.VersionControlGetLatest()' to update a number of Packages, or after performing a number of Package check-outs.
