    static final long
    F_FINE_GRAINED

    Change flag constant (bit-mask) indicating that the element was moved to another location.
    static final long
    F_OPEN
    Change flag constant (bit-mask) indicating that the underlying IProject has been opened or closed.
    static final long
    F_REORDER
    Change flag constant (bit-mask) indicating that the element has changed position relatively to its siblings.
    static final long
    F_SYNC
    Change flag constant (bit-mask) indicating that sync status of the element's corresponding resource has changed.
    static final long
    F_UNDERLYING_RESOURCE
    Change flag constant (bit-mask) indicating that the underlying IFile of a working copy has changed.
    static final long
    F_WORKING_COPY
    Change flag constant (bit-mask) indicating that a source file has become a working copy, or that a working copy has reverted to a source file.
    static final int
    NO_CHANGE
    Delta kind constant indicating that the element has not been changed in any way.
    static final int
    REMOVED
    Delta kind constant indicating that the element has been removed from its parent.

  • Field Details

    • NO_CHANGE

      static final int NO_CHANGE
      Delta kind constant indicating that the element has not been changed in any way.
      See Also:

    • ADDED

      static final int ADDED
      Delta kind constant indicating that the element has been added to its parent. Note that an added element delta has no children, as they are all implicitly added.
      See Also:

    • REMOVED

      static final int REMOVED
      Delta kind constant indicating that the element has been removed from its parent. Note that a removed element delta has no children, as they are all implicitly removed.
      See Also:

    • CHANGED

      static final int CHANGED
      Delta kind constant indicating that the element has been changed, as described by change flag constants.
      See Also:

    • F_CONTENT

      static final long F_CONTENT
      Change flag constant (bit-mask) indicating that the content of the element has changed.
      See Also:

    • F_CHILDREN

      static final long F_CHILDREN
      Change flag constant (bit-mask) indicating that there are changes to the children of the element.
      See Also:

    • F_MOVED_FROM

      static final long F_MOVED_FROM
      Change flag constant (bit-mask) indicating that the element was moved from another location.
      See Also:

    • F_MOVED_TO

      static final long F_MOVED_TO
      Change flag constant (bit-mask) indicating that the element was moved to another location.
      See Also:

    • F_REORDER

      static final long F_REORDER
      Change flag constant (bit-mask) indicating that the element has changed position relatively to its siblings.
      See Also:

    • F_FINE_GRAINED

      static final long F_FINE_GRAINED
      Change flag constant (bit-mask) indicating that this is a fine-grained delta, that is, an analysis down to the source constructs level was done to determine if there were structural changes to source constructs.

      Clients can use this flag to find out if a source file that has an F_CONTENT change should assume that there are no finer grained changes (F_FINE_GRAINED is set) or if finer grained changes were not considered (F_FINE_GRAINED is not set).

      See Also:

    • F_OPEN

      static final long F_OPEN
      Change flag constant (bit-mask) indicating that the underlying IProject has been opened or closed. This flag is only valid if the element represents a project.
      See Also:

    • F_DESCRIPTION

      static final long F_DESCRIPTION
      Change flag constant (bit-mask) indicating that the underlying IProject's description has changed. This flag is only valid if the element represents a project.
      See Also:

    • F_WORKING_COPY

      static final long F_WORKING_COPY
      Change flag constant (bit-mask) indicating that a source file has become a working copy, or that a working copy has reverted to a source file. This flag is only valid if the element represents a source file.
      See Also:

    • F_UNDERLYING_RESOURCE

      static final long F_UNDERLYING_RESOURCE
      Change flag constant (bit-mask) indicating that the underlying IFile of a working copy has changed. This flag is only valid if the element represents a source file.
      See Also:

    • F_MARKERS

      static final long F_MARKERS
      Change flag constant (bit-mask) indicating that markers on the element's corresponding resource have changed. This flag is only valid if the element has a corresponding resource.
      See Also:

    • F_SYNC

      static final long F_SYNC
      Change flag constant (bit-mask) indicating that sync status of the element's corresponding resource has changed. This flag is only valid if the element has a corresponding resource.
