    • codeComplete

      public void codeComplete(int offset, CompletionRequestor requestor, WorkingCopyOwner owner, org.eclipse.core.runtime.IProgressMonitor monitor) throws JavaModelException
      Beschreibung aus Schnittstelle kopiert: ICodeAssist
      Performs code completion at the given offset position in this compilation unit, reporting results to the given completion requestor. The offset is the 0-based index of the character, after which code assist is desired. An offset of -1 indicates to code assist at the beginning of this compilation unit. It considers types in the working copies with the given owner first. In other words, the owner's working copies will take precedence over their original compilation units in the workspace.

      Note that if a working copy is empty, it will be as if the original compilation unit had been deleted.

      If IProgressMonitor is not null then some proposals which can be very long to compute are proposed. To avoid that the code assist operation take too much time a IProgressMonitor which automatically cancel the code assist operation when a specified amount of time is reached could be used. 

       new IProgressMonitor() {
     private final static int TIMEOUT = 500; //ms
     private long endTime;
     public void beginTask(String name, int totalWork) {
         fEndTime= System.currentTimeMillis() + TIMEOUT;
     }
     public boolean isCanceled() {
         return endTime Ungültige Eingabe: "<"= System.currentTimeMillis();

      Parameter:
      offset - the given offset position
      requestor - the given completion requestor
      owner - the owner of working copies that take precedence over their original compilation units
      monitor - the progress monitor used to report progress
      Löst aus:

      • This Java element does not exist (ELEMENT_DOES_NOT_EXIST)

    • codeSelect

      public IJavaElement[] codeSelect(int offset, int length, WorkingCopyOwner owner) throws JavaModelException
      Beschreibung aus Schnittstelle kopiert: ICodeAssist
      Returns the Java elements corresponding to the given selected text in this compilation unit. The offset is the 0-based index of the first selected character. The length is the number of selected characters. It considers types in the working copies with the given owner first. In other words, the owner's working copies will take precedence over their original compilation units in the workspace.

      Note that if the length is 0 and the offset is inside an identifier or the index just after an identifier then this identifier is considered as the selection.

      Note that if a working copy is empty, it will be as if the original compilation unit had been deleted.

    • getWorkingCopy

      public ICompilationUnit getWorkingCopy(WorkingCopyOwner owner, org.eclipse.core.runtime.IProgressMonitor monitor) throws JavaModelException
      Beschreibung aus Schnittstelle kopiert: ITypeRoot
      Returns a shared working copy on this compilation unit or class file using the given working copy owner to create the buffer. If this is already a working copy of the given owner, the element itself is returned. This API can only answer an already existing working copy if it is based on the same original Java type root AND was using the same working copy owner (that is, as defined by Object.equals(java.lang.Object)).

      The life time of a shared working copy is as follows:

      So users of this method must discard exactly once the working copy.

      Note that the working copy owner will be used for the life time of the shared working copy, that is if the working copy is closed then reopened, this owner will be used. The buffer will be automatically initialized with the original's Java type root content upon creation.

      When the shared working copy instance is created, an ADDED IJavaElementDelta is reported on this working copy.

      A working copy can be created on a not-yet existing compilation unit. In particular, such a working copy can then be committed in order to create the corresponding compilation unit.

      Note that possible problems of this working copy are reported using this method only if the given working copy owner returns a problem requestor for this working copy (see WorkingCopyOwner.getProblemRequestor(ICompilationUnit)).

      getWorkingCopy in Schnittstelle ITypeRoot
      Parameter:
      owner - the working copy owner that creates a buffer that is used to get the content of the working copy
      monitor - a progress monitor used to report progress while opening this compilation unit or null if no progress should be reported
      Gibt zurück:
      a new working copy of this Java type root using the given owner to create the buffer, or this Java type root if it is already a working copy
      Löst aus:
      JavaModelException - if the contents of this element can not be determined.

    • exists

      public boolean exists()
      Beschreibung aus Schnittstelle kopiert: IJavaElement
      Returns whether this Java element exists in the model.

      Java elements are handle objects that may or may not be backed by an actual element. Java elements that are backed by an actual element are said to "exist", and this method returns true. For Java elements that are not working copies, it is always the case that if the element exists, then its parent also exists (provided it has one) and includes the element as one of its children. It is therefore possible to navigated to any existing Java element from the root of the Java model along a chain of existing Java elements. On the other hand, working copies are said to exist until they are destroyed (with IWorkingCopy.destroy). Unlike regular Java elements, a working copy never shows up among the children of its parent element (which may or may not exist).
