      • Workspace

        public Workspace​(java.io.File workspaceDir)

        public Workspace​(java.io.File workspaceDir,
                 java.lang.String bndDir)
          throws java.lang.Exception
        Create a workspace with the given directory and the bnd directory, normally cnf. (Though there are some use cases where this is in another place.) This will create a WorkspaceLayout.BND layout set the base to the workspaceDir, and read the properties in the `build.bnd` file in the bndDir sub directory.

        This will read the version specific defaults after the properties are read from build.bnd in an _intermediate_ processor.

        Parameters:
        workspaceDir - the workspace directory
        bndDir - the bnd directory with build.bnd
        Throws:

        Lock the workspace for all functions including modification. The callable parameter when called can freely use any function in the workspace. After the callable returns, the write lock is downgraded to a read lock and the function is called with the result of the callable.
        Parameters:
        underWrite - the Callable to run under the write lock
        underRead - the Function to run under the read lock
        canceled - Has the operation been cancelled?
        timeoutInMs - the timeout in milliseconds
        Returns:
        the value of the function
        Throws:
        java.lang.InterruptedException - If the thread is interrupted while waiting for the lock.
        java.util.concurrent.TimeoutException - If the lock was not obtained within the timeout period or the specified monitor is cancelled while waiting to obtain the lock.
        java.lang.Exception - If the callable or function throws an exception.

      • search

        public Result<java.util.Map<java.lang.String,​java.util.List<BundleId>>> search​(java.lang.String partialFqn)
                                                                              throws java.lang.Exception
        Search for a partial class name. The partialFqn name may be a simple class name (Foo) or a fully qualified class name line (foo.bar.Foo), including nested classes, or only a package name prefix (foo.bar or even foo.ba).

        This method uses the heuristic in determine() to split the package name from the (possibly nested) class name - the start of the class name is taken as the first element that starts with a capital letter. This heuristic works fine in most cases, but it is not foolproof. In contexts where you have a better idea of how to separate the package name from the class name, you can use search(String, String) for this purpose.

        Parameters:
        partialFqn - a packagename ( '.' classname )*
        Returns:
        a multi-map containing the search matches with the matching fully-qualified class name as each entry's key, and a list of matching bundles as the value.
        Throws:
        java.lang.Exception

        Search for a class name inside particular package. Use this in preference to search(String) when you know that the qualifier resolves to a package and not to a class.
        Parameters:
        packageName - the package to search
        className - a classname ( '.' classname )*
        Returns:
