java.lang.Object

com.ptteng.course.util.aliPayUtil.apacheCommonUtil.codec.StringEncoderComparator

所有已实现的接口:

Comparator

public class StringEncoderComparator
extends Object
implements Comparator

Compares Strings using a StringEncoder. This comparator is used to sort Strings by an encoding scheme such as Soundex, Metaphone, etc. This class can come in handy if one need to sort Strings by an encoded form of a name such as Soundex.

This class is immutable and thread-safe.

方法详细资料

compare

public int compare(Object o1,
                   Object o2)

Compares two strings based not on the strings themselves, but on an encoding of the two strings using the StringEncoder this Comparator was created with. If an EncoderException is encountered, return 0.

指定者:

compare 在接口中 Comparator

参数:

o1 - the object to compare

o2 - the object to compare to

返回:
