Method Detail

create

public static StringSwitcher create(java.lang.String[] strings,
                                    int[] ints,
                                    boolean fixedInput)

Helper method to create a StringSwitcher. For finer control over the generated instance, use a new instance of StringSwitcher.Generator instead of this static method.

Parameters:

strings - the array of String keys; must be the same length as the value array

ints - the array of integer results; must be the same length as the key array

fixedInput - if false, an unknown key will be returned from intValue(java.lang.String) as -1; if true, the result will be undefined, and the resulting code will be faster

intValue

public abstract int intValue(java.lang.String s)

Return the integer associated with the given key.

Parameters:

s - the key

Returns:

the associated integer value, or -1 if the key is unknown (unless fixedInput was specified when this StringSwitcher was created, in which case the return value for an unknown key is undefined)
