Class PhoneticEngine.RulesApplication

java.lang.Object

org.apache.commons.codec.language.bm.PhoneticEngine.RulesApplication

Enclosing class:

PhoneticEngine

private static final class PhoneticEngine.RulesApplication
extends java.lang.Object

A function closure capturing the application of a list of rules to an input sequence at a particular offset. After invocation, the values i and found are updated. i points to the index of the next char in input that must be processed next (the input up to that index having been processed already), and found indicates if a matching rule was found or not. In the case where a matching rule was found, phonemeBuilder is replaced with a new builder containing the phonemes updated by the matching rule. Although this class is not thread-safe (it has mutable unprotected fields), it is not shared between threads as it is constructed as needed by the calling methods.

public RulesApplication(java.util.Map<java.lang.String,java.util.List<Rule>> finalRules,
                        java.lang.CharSequence input,

Method Detail

getI

public int getI()

getPhonemeBuilder

public PhoneticEngine.PhonemeBuilder getPhonemeBuilder()

invoke

public PhoneticEngine.RulesApplication invoke()

Invokes the rules. Loops over the rules list, stopping at the first one that has a matching context and pattern. Then applies this rule to the phoneme builder to produce updated phonemes. If there was no match, i is advanced one and the character is silently dropped from the phonetic spelling.

Returns:

isFound

public boolean isFound()
