        public DocprocExecutor​(java.lang.String name,
                       CallStack callStack)
        Creates a new named DocprocExecutor with the given CallStack.
        Parameters:

        public DocprocExecutor​(DocprocExecutor oldExecutor,
                       CallStack callStack)
        Creates a new named DocprocExecutor, with the same instance variables as the given executor, but a new call stack.
        Parameters:
        oldExecutor - the executor to inherit the instance variables from, sans call stack.

      • process

        public DocumentProcessor.Progress process​(Processing processing)
        Processes a given Processing through the CallStack of this executor.
        Parameters:
        processing - the Processing to process. The CallStack of the Processing will be set to a clone of the CallStack of this executor, iff. it is currently null.
        Returns:
        a Progress; if this is LATER, the Processing is not done and must be reprocessed later.
        Throws:
        java.lang.RuntimeException - if a document processor throws an exception during processing.

      • processUntilDone

        public DocumentProcessor.Progress processUntilDone​(Processing processing)
        Processes a given Processing through the CallStack of this executor. Note that if a DocumentProcessor returns a LaterProgress for this processing, it will be re-processed (after waiting the specified delay given by the LaterProgress), until done or failed.
        Parameters:
        processing - the Processing to process. The CallStack of the Processing will be set to a clone of the CallStack of this executor, iff. it is currently null.
        Returns:
        a Progress; this is never a LaterProgress.
        Throws:
        java.lang.RuntimeException - if a document processor throws an exception during processing, or this thread is interrupted while waiting.
