Method Details

as

public static <T> T as(Class<T> t,
 Object o)

compareAndSet

public static <T> boolean compareAndSet(T[] array,
 T expectedValue,
 T newValue,
 int index)

Performs CAS on the array element at the given index.

Type Parameters:

T - the type of elements in the array

Parameters:

array - the array in which to compare and set the value

expectedValue - the value expected to be at the index

newValue - the new value to be set at the index if the expected value matches

index - the index at which to compare and set the value

Returns:

true if the value at the index was successfully updated to the new value, false otherwise
