Class MorpherRegistry

  • All Implemented Interfaces:
    java.io.Serializable
    public class MorpherRegistry
extends java.lang.Object
implements java.io.Serializable
    Convenient class that manages Morphers.
    A MorpherRehistry manages a group of Morphers. A Morpher will always be associated with a target class, it is possible to have several Morphers registered for a target class, if this is the case, the first Morpher will be used when performing a conversion and no specific Morpher is selected in advance.
    MorphUtils may be used to register standard Morphers for primitive types and primitive wrappers, as well as arrays of those types.

      Modifier and Type Method Description
      void clear()
      Deregisters all morphers.
      void clear​(java.lang.Class type)
      Deregister all Morphers of a type.
      void deregisterMorpher​(Morpher morpher)
      Deregister the specified Morpher.
      The registry will remove the target Class from the morphers Map if it has no other registered morphers.
      Morpher getMorpherFor​(java.lang.Class clazz)
      Returns a morpher for clazz.
      If several morphers are found for that class, it returns the first.
      Morpher[] getMorphersFor​(java.lang.Class clazz)
      Returns all morphers for clazz.
      If no Morphers are found it will return an array containing the IdentityObjectMorpher.
      java.lang.Object morph​(java.lang.Class target, java.lang.Object value)
      Morphs and object to the specified target class.
      This method uses reflection to invoke primitive Morphers and Morphers that do not implement ObjectMorpher.
      void registerMorpher​(Morpher morpher)
      Register a Morpher for a target Class.
      The target class is the class this Morpher morphs to.
      void registerMorpher​(Morpher morpher, boolean override)
      Register a Morpher for a target Class.
      The target class is the class this Morpher morphs to.

        public void clear()
        Deregisters all morphers.

      • clear

        public void clear​(java.lang.Class type)
        Deregister all Morphers of a type.
        Parameters:
        class - the target type the Morphers morph to

      • deregisterMorpher

        public void deregisterMorpher​(Morpher morpher)
        Deregister the specified Morpher.
        The registry will remove the target Class from the morphers Map if it has no other registered morphers.
        Parameters:
        morpher - the target Morpher to remove

      • getMorpherFor

        public Morpher getMorpherFor​(java.lang.Class clazz)
        Returns a morpher for clazz.
        If several morphers are found for that class, it returns the first. If no Morpher is found it will return the IdentityObjectMorpher.
        Parameters:
        clazz - the target class for which a Morpher may be associated

      • getMorphersFor

        public Morpher[] getMorphersFor​(java.lang.Class clazz)
        Returns all morphers for clazz.
        If no Morphers are found it will return an array containing the IdentityObjectMorpher.
        Parameters:
        clazz - the target class for which a Morpher or Morphers may be associated

      • morph

        public java.lang.Object morph​(java.lang.Class target,
                              java.lang.Object value)
        Morphs and object to the specified target class.
        This method uses reflection to invoke primitive Morphers and Morphers that do not implement ObjectMorpher.
        Parameters:
        target - the target class to morph to
        value - the value to morph
        Returns:
        an instance of the target class if a suitable Morpher was found
        Throws:
        MorphException - if an error occurs during the conversion

      • registerMorpher

        public void registerMorpher​(Morpher morpher)
        Register a Morpher for a target Class.
        The target class is the class this Morpher morphs to. If there are another morphers registered to that class, it will be appended to a List.
        Parameters:
        morpher - a Morpher to register. The method morphsTo() is used to associate the Morpher to a target Class

      • registerMorpher

        public void registerMorpher​(Morpher morpher,
                            boolean override)
        Register a Morpher for a target Class.
        The target class is the class this Morpher morphs to. If there are another morphers registered to that class, it will be appended to a List.
        Parameters:
        morpher - a Morpher to register. The method morphsTo() is used to associate the Morpher to a target Class
        override - if registering teh Morpher should override all previously registered morphers for the target type
