->atomic-reference-arrayclj
(->atomic-reference-array length)Constructor.
Creates a new AtomicReferenceArray of the given length, with all elements initially null.
length - the length of the array - int
Constructor. Creates a new AtomicReferenceArray of the given length, with all elements initially null. length - the length of the array - `int`
accumulate-and-getclj
(accumulate-and-get this i x accumulator-function)Atomically updates the element at index i with the results of applying the given function to the current and given values, returning the updated value. The function should be side-effect-free, since it may be re-applied when attempted updates fail due to contention among threads. The function is applied with the current value at index i as its first argument, and the given update as the second argument.
i - the index - int
x - the update value - E
accumulator-function - a side-effect-free function of two arguments - java.util.function.BinaryOperator
returns: the updated value - E
Atomically updates the element at index i with the results of applying the given function to the current and given values, returning the updated value. The function should be side-effect-free, since it may be re-applied when attempted updates fail due to contention among threads. The function is applied with the current value at index i as its first argument, and the given update as the second argument. i - the index - `int` x - the update value - `E` accumulator-function - a side-effect-free function of two arguments - `java.util.function.BinaryOperator` returns: the updated value - `E`
compare-and-setclj
(compare-and-set this i expect update)Atomically sets the element at position i to the given updated value if the current value == the expected value.
i - the index - int
expect - the expected value - E
update - the new value - E
returns: true if successful. False return indicates that
the actual value was not equal to the expected value. - boolean
Atomically sets the element at position i to the given updated value if the current value == the expected value. i - the index - `int` expect - the expected value - `E` update - the new value - `E` returns: true if successful. False return indicates that the actual value was not equal to the expected value. - `boolean`
getclj
(get this i)Gets the current value at position i.
i - the index - int
returns: the current value - E
Gets the current value at position i. i - the index - `int` returns: the current value - `E`
get-and-accumulateclj
(get-and-accumulate this i x accumulator-function)Atomically updates the element at index i with the results of applying the given function to the current and given values, returning the previous value. The function should be side-effect-free, since it may be re-applied when attempted updates fail due to contention among threads. The function is applied with the current value at index i as its first argument, and the given update as the second argument.
i - the index - int
x - the update value - E
accumulator-function - a side-effect-free function of two arguments - java.util.function.BinaryOperator
returns: the previous value - E
Atomically updates the element at index i with the results of applying the given function to the current and given values, returning the previous value. The function should be side-effect-free, since it may be re-applied when attempted updates fail due to contention among threads. The function is applied with the current value at index i as its first argument, and the given update as the second argument. i - the index - `int` x - the update value - `E` accumulator-function - a side-effect-free function of two arguments - `java.util.function.BinaryOperator` returns: the previous value - `E`
get-and-setclj
(get-and-set this i new-value)Atomically sets the element at position i to the given value and returns the old value.
i - the index - int
new-value - the new value - E
returns: the previous value - E
Atomically sets the element at position i to the given value and returns the old value. i - the index - `int` new-value - the new value - `E` returns: the previous value - `E`
get-and-updateclj
(get-and-update this i update-function)Atomically updates the element at index i with the results of applying the given function, returning the previous value. The function should be side-effect-free, since it may be re-applied when attempted updates fail due to contention among threads.
i - the index - int
update-function - a side-effect-free function - java.util.function.UnaryOperator
returns: the previous value - E
Atomically updates the element at index i with the results of applying the given function, returning the previous value. The function should be side-effect-free, since it may be re-applied when attempted updates fail due to contention among threads. i - the index - `int` update-function - a side-effect-free function - `java.util.function.UnaryOperator` returns: the previous value - `E`
lazy-setclj
(lazy-set this i new-value)Eventually sets the element at position i to the given value.
i - the index - int
new-value - the new value - E
Eventually sets the element at position i to the given value. i - the index - `int` new-value - the new value - `E`
lengthclj
(length this)Returns the length of the array.
returns: the length of the array - int
Returns the length of the array. returns: the length of the array - `int`
setclj
(set this i new-value)Sets the element at position i to the given value.
i - the index - int
new-value - the new value - E
Sets the element at position i to the given value. i - the index - `int` new-value - the new value - `E`
to-stringclj
(to-string this)Returns the String representation of the current values of array.
returns: the String representation of the current values of array - java.lang.String
Returns the String representation of the current values of array. returns: the String representation of the current values of array - `java.lang.String`
update-and-getclj
(update-and-get this i update-function)Atomically updates the element at index i with the results of applying the given function, returning the updated value. The function should be side-effect-free, since it may be re-applied when attempted updates fail due to contention among threads.
i - the index - int
update-function - a side-effect-free function - java.util.function.UnaryOperator
returns: the updated value - E
Atomically updates the element at index i with the results of applying the given function, returning the updated value. The function should be side-effect-free, since it may be re-applied when attempted updates fail due to contention among threads. i - the index - `int` update-function - a side-effect-free function - `java.util.function.UnaryOperator` returns: the updated value - `E`
weak-compare-and-setclj
(weak-compare-and-set this i expect update)Atomically sets the element at position i to the given updated value if the current value == the expected value.
May fail spuriously and does not provide ordering guarantees, so is only rarely an appropriate alternative to compareAndSet.
i - the index - int
expect - the expected value - E
update - the new value - E
returns: true if successful - boolean
