Helper method to create a StringSwitcher.

public abstract int

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)
intValue(String
the key

Method Detail

createback to summary
public static StringSwitcher create(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:String[]

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

ints:int[]

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

fixedInput:boolean

if false, an unknown key will be returned from intValue as -1; if true, the result will be undefined, and the resulting code will be faster

intValueback to summary
public abstract int intValue(String s)

Return the integer associated with the given key.

Parameters
s:String

the key

Returns:int

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)
