## Class AbstractCaverphone

- java.lang.Object
- - org.apache.commons.codec.language.AbstractCaverphone

- All Implemented Interfaces:
    Encoder, StringEncoder
  Direct Known Subclasses:
    Caverphone1, Caverphone2

      public abstract class AbstractCaverphone
      extends Object
      implements StringEncoder

  Encodes a string into a Caverphone value. This is an algorithm created by the Caversham Project at the University of Otago. It implements the Caverphone 2.0 algorithm:

  This class is immutable and thread-safe.

      Creates an instance of the Caverphone encoder

  - ### Method Detail

    - #### encode

          public Object encode(Object source)
                        throws EncoderException

      Encodes an Object using the caverphone algorithm. This method is provided in order to satisfy the requirements of the Encoder interface, and will throw an EncoderException if the supplied object is not of type java.lang.String.
      Specified by:
        `encode` in interface `Encoder`
      Parameters:
        `source` - Object to encode
      Returns:
        An object (or type java.lang.String) containing the caverphone code which corresponds to the String supplied.
      Throws:
        `EncoderException` - if the parameter supplied is not of type java.lang.String

    - #### isEncodeEqual

          public boolean isEncodeEqual(String str1,
                                       String str2)
                                throws EncoderException

      Tests if the encodings of two strings are equal. This method might be promoted to a new AbstractStringEncoder superclass.
      Parameters:
        `str1` - First of two strings to compare
        `str2` - Second of two strings to compare
      Returns:
        `true` if the encodings of these strings are identical, `false` otherwise.
      Throws:
        `EncoderException` - thrown if there is an error condition during the encoding process.
