  • All Implemented Interfaces:
    Path, java.io.Serializable
    public class QualifiedPath
extends java.lang.Object
implements java.io.Serializable, Path
    This class is a path to anything in Ignition, across any system. It dictates how the path is formed, but the actual meaning of different subcomponents will depend on the context in which the path is used.

                            java.lang.String beforeComponentId)
        Locates the component specified and inserts the new component before it.

      • getPathLength

        public int getPathLength()
        Description copied from interface: Path
        Returns the number of elements in the path, which can be retrieved through getPathComponent().

        Description copied from interface: Path
        Returns the path element at the specified location.
        Specified by:
        getPathComponent in interface Path

      • getLastPathComponent

        public java.lang.String getLastPathComponent()
        Description copied from interface: Path
        Convenience function to return the last path element.
        Specified by:
        getLastPathComponent in interface Path

        public java.lang.String getFirstPathComponent()

      • getFirstPathComponentId

        public java.lang.String getFirstPathComponentId()

      • subpath

        public QualifiedPath subpath()
        Removes the first path component and returns the rest as a new path.

      • subpath

        public QualifiedPath subpath​(java.lang.String id)
        Returns the paths that comes after the first instance of the specified id.
        Parameters:
        id - component id after which the subsequent path parts will be returned.
        Returns:
        everything after the specified id, or null if id is not found.

      • strip

        public QualifiedPath strip()
        Removes the last fully-qualified component from the path. This differs from getParentPath() in that that function doesn't care whether the component is qualified or not.

        Removes the given component, if present.
