| Arrays | | public class Arrays (Code) | | A class providing static methods and objects that do useful things with arrays.
See Also: Arrays |
| Method Summary | |
| public static void | ensureFromTo(int arrayLength, int from, int to)
Ensures that a range given by its first (inclusive) and last (exclusive) elements fits an array of given length. | | public static void | ensureOffsetLength(int arrayLength, int offset, int length)
Ensures that a range given by an offset and a length fits an array of given length. |
| ensureFromTo | | public static void ensureFromTo(int arrayLength, int from, int to)(Code) | | Ensures that a range given by its first (inclusive) and last (exclusive) elements fits an array of given length.
This method may be used whenever an array range check is needed.
Parameters:
arrayLength - an array length.
Parameters:
from - a start index (inclusive).
Parameters:
to - an end index (inclusive).
throws:
IllegalArgumentException - if from is greater than to.
throws:
ArrayIndexOutOfBoundsException - if from or to are greater than arrayLength or negative. |
| ensureOffsetLength | | public static void ensureOffsetLength(int arrayLength, int offset, int length)(Code) | | Ensures that a range given by an offset and a length fits an array of given length.
This method may be used whenever an array range check is needed.
Parameters:
arrayLength - an array length.
Parameters:
offset - a start index for the fragment
Parameters:
length - a length (the number of elements in the fragment).
throws:
IllegalArgumentException - if length is negative.
throws:
ArrayIndexOutOfBoundsException - if offset is negative or offset+length is greater than arrayLength. |
