All Implemented Interfaces:

Encoder, StringEncoder
```
public class BeiderMorseEncoder
extends java.lang.Object
implements StringEncoder
```
Encodes strings into their Beider-Morse phonetic encoding.
Beider-Morse phonetic encodings are optimised for family names. However, they may be useful for a wide range of words.
This encoder is intentionally mutable to allow dynamic configuration through bean properties. As such, it is mutable, and may not be thread-safe. If you require a guaranteed thread-safe encoding then use PhoneticEngine directly.
Encoding overview
Beider-Morse phonetic encodings is a multi-step process. Firstly, a table of rules is consulted to guess what language the word comes from. For example, if it ends in "ault" then it infers that the word is French. Next, the word is translated into a phonetic representation using a language-specific phonetics table. Some runs of letters can be pronounced in multiple ways, and a single run of letters may be potentially broken up into phonemes at different places, so this stage results in a set of possible language-specific phonetic representations. Lastly, this language-specific phonetic representation is processed by a table of rules that re-writes it phonetically taking into account systematic pronunciation differences between languages, to move it towards a pan-indo-european phonetic representation. Again, sometimes there are multiple ways this could be done and sometimes things that can be pronounced in several ways in the source language have only one way to represent them in this average phonetic language, so the result is again a set of phonetic spellings.
Some names are treated as having multiple parts. This can be due to two things. Firstly, they may be hyphenated. In this case, each individual hyphenated word is encoded, and then these are combined end-to-end for the final encoding. Secondly, some names have standard prefixes, for example, "Mac/Mc" in Scottish (English) names. As sometimes it is ambiguous whether the prefix is intended or is an accident of the spelling, the word is encoded once with the prefix and once without it. The resulting encoding contains one and then the other result.
Encoding format
Individual phonetic spellings of an input word are represented in upper- and lower-case roman characters. Where there are multiple possible phonetic representations, these are joined with a pipe (|) character. If multiple hyphenated words where found, or if the word may contain a name prefix, each encoded word is placed in elipses and these blocks are then joined with hyphens. For example, "d'ortley" has a possible prefix. The form without prefix encodes to "ortlaj|ortlej", while the form with prefix encodes to " dortlaj|dortlej". Thus, the full, combined encoding is "(ortlaj|ortlej)-(dortlaj|dortlej)".
The encoded forms are often quite a bit longer than the input strings. This is because a single input may have many potential phonetic interpretations. For example, "Renault" encodes to " rYnDlt|rYnalt|rYnult|rinDlt|rinalt|rinult". The APPROX rules will tend to produce larger encodings as they consider a wider range of possible, approximate phonetic interpretations of the original word. Down-stream applications may wish to further process the encoding for indexing or lookup purposes, for example, by splitting on pipe (|) and indexing under each of these alternatives.
Note: this version of the Beider-Morse encoding is equivalent with v3.4 of the reference implementation.

                        throws EncoderException
```
    Description copied from interface: Encoder
    
    Encodes an "Object" and returns the encoded content as an Object. The Objects here may just be byte[] or Strings depending on the implementation used.
    
    Specified by:
    
    encode in interface Encoder
    
    Parameters:
    
    source - An object to encode
    
    Returns:
    
    An "encoded" Object
    
    Throws:
    
    EncoderException - An encoder exception is thrown if the encoder experiences a failure condition during the encoding process.
  - encode
```
public java.lang.String encode(java.lang.String source)

    Specified by:
    
    encode in interface StringEncoder
    
    Parameters:
    
    source - the String to encode
    
    Returns:
    
    the encoded String

  - setNameType
```
public void setNameType(NameType nameType)
```
    Sets the type of name. Use NameType.GENERIC unless you specifically want phonetic encodings optimized for Ashkenazi or Sephardic Jewish family names.
    
    Parameters:
    
    nameType - the NameType in use
  - setRuleType
```
public void setRuleType(RuleType ruleType)
