Interface IJavaCompletionProposalComputer

public interface IJavaCompletionProposalComputer
Computes completions and context information displayed by the Java editor content assistant. Contributions to the org.eclipse.jdt.ui.javaCompletionProposalComputer extension point must implement this interface.

  • Method Details

    • sessionStarted

      void sessionStarted()
      Informs the computer that a content assist session has started. This call will always be followed by a sessionEnded() call, but not necessarily by calls to computeCompletionProposals or computeContextInformation.

    • computeCompletionProposals

      List<ICompletionProposal> computeCompletionProposals(ContentAssistInvocationContext context, IProgressMonitor monitor)
      Returns a list of completion proposals valid at the given invocation context.
      Parameters:
      context - the context of the content assist invocation
      monitor - a progress monitor to report progress. The monitor is private to this invocation, i.e. there is no need for the receiver to spawn a sub monitor.
      Returns:
      a list of completion proposals (element type: ICompletionProposal)

    • computeContextInformation

      List<IContextInformation> computeContextInformation(ContentAssistInvocationContext context, IProgressMonitor monitor)
      Returns context information objects valid at the given invocation context.
      Parameters:
      context - the context of the content assist invocation
      monitor - a progress monitor to report progress. The monitor is private to this invocation, i.e. there is no need for the receiver to spawn a sub monitor.
      Returns:
      a list of context information objects (element type: IContextInformation)

    • getErrorMessage

      String getErrorMessage()
      Returns the reason why this computer was unable to produce any completion proposals or context information.
      Returns:
      an error message or null if no error occurred

    • sessionEnded

      void sessionEnded()
      Informs the computer that a content assist session has ended. This call will always be after any calls to computeCompletionProposals and computeContextInformation.
