Method Detail

apply

public final char[] apply(char[] text,
           char[] target,
           char[] replacement,
           Integer firstId)
                   throws NotAppliedException,
                          Lang.Break

Apply the function to replace all target in text with replacement and return a char[] contains the result with all target replaced with replacement

Specified by:

apply in interface Lang.Func4<char[],char[],char[],Integer,char[]>

Parameters:

text - the text

target - the target to search

replacement - the replacement of target

firstId - the first index of targe inside text. If negative means not searched yet

Returns:

the replaced result as described above

Throws:

NotAppliedException

$.Break

Lang.Break - to short cut collecting operations (fold/reduce) on an container

replace

public abstract char[] replace(char[] text,
             char[] target,
             char[] replacement,
             int firstId)

Sub class shall implement the replacement logic in this method

Parameters:

text - the text in which search string will be replaced

target - the target string to be replaced

replacement - the replacement string

firstId - the first index of targe inside text. If negative means not searched yet

Returns:

result of the replacement

wrap

public static StringReplace wrap(Lang.Func4<char[],char[],char[],Integer,char[]> replaceLogic)
