Given we have a value for path "/dog/cat" in the PathMap and we call PathMap.retrieveFrom(String) with "/dog", then the resulting PathMap will contain the path "/cat" for that value.
        Specified by:
        retrieveFrom in interface PathMap<T>

Given we have a value for path "/dog/cat" in the PathMap and we call PathMap.retrieveTo(String) with "/animals", then the resulting PathMap will contain the path "/animals/dog/cat" for that value.
        Specified by:
        retrieveTo in interface PathMap<T>
        Parameters:
        aToPath - The path where to relocate the paths of this PathMap to.
        Returns:
        The PathMap with the elements from the provided PathMap with accordingly relocated paths.
      • getType

        public java.lang.Class<T> getType​()

        getType in interface org.refcodes.mixin.TypeAccessor<T>
      • toDataStructure

        public java.lang.Object toDataStructure​(java.lang.String aFromPath)
        Similar to the PathMap.toMap(String) method, though in case all the keys of a nested Map instance (applicable to the root Map as well) represent an array (as of PathMap.getArray( String)), then an array is generated where the index of each value in the Map is represented by the number representation of the Map's key for that value. The result is a data structure consisting of Map instances and arrays.
        Specified by:
        toDataStructure in interface PathMap<T>
        Parameters:
        aFromPath - The path below which the PathMap to be converted into a data structure.
        Returns:
        A data structure being a mixture of Map instances and arrays representing the data below the given path.
