Method Detail

getLongVolatile

long getLongVolatile(int index)

Get the value at a given index with volatile semantics.

Parameters:

index - The index in bytes from where to get the value.

Returns:

The value retrieved from the given index.

putLongVolatile

void putLongVolatile(int index,
                     long value)

Put a value to a given index with volatile semantics.

Parameters:

index - The index in bytes for where to put the value.

value - The value to put at the given index.

putLongOrdered

void putLongOrdered(int index,
                    long value)

Put a value to a given index with ordered store semantics.

Parameters:

index - The index in bytes for where to put the value.

value - The value to put at the given index.

addLongOrdered

void addLongOrdered(int index,
                    long increment)

Add a value to a given index with ordered store semantics. Use a negative increment to decrement.

Parameters:

index - The index in bytes for where to increment or decrement the value.

increment - The increment or decrement by which the value at the index will be adjusted.

compareAndSetLong

boolean compareAndSetLong(int index,
                          long expectedValue,
                          long updateValue)

Performs an atomic compare and set of a long, given an expected value.

Parameters:

index - The index in bytes for where to put the value.

expectedValue - at to be compared The expected value that is compared to the value at the index.

updateValue - The value to be exchanged with the value at the index.

Returns:

true if the compare and put were successful, false otherwise.

getIntVolatile

int getIntVolatile(int index)

Get the value at a given index with volatile semantics.

Parameters:

index - The index in bytes from where to get the value.

Returns:

The value retrieved from the given index.

putIntVolatile

void putIntVolatile(int index,
                    int value)

Put a value to a given index with volatile semantics.

Parameters:

index - The index in bytes for where to put the value.

value - The value to put at the given index.

putIntOrdered

void putIntOrdered(int index,
                   int value)

Put a value to a given index with ordered semantics.

Parameters:

index - The index in bytes for where to put the value.

value - The value to put at the given index.

addIntOrdered

void addIntOrdered(int index,
                   int increment)

Add a value to a given index with ordered store semantics. Use a negative increment to decrement.

Parameters:

index - The index in bytes for where to put the value.

increment - by which the value at the index will be adjusted.

compareAndSetInt

boolean compareAndSetInt(int index,
                         int expectedValue,
                         int updateValue)

Atomic compare and set of a int given an expected value.

Parameters:

index - The index in bytes for where to put the value.

expectedValue - at to be compared The expected value that is compared to the value at the index.

updateValue - The value to be exchanged with the value at the index.

Returns:

true if the compare and put were successful, false otherwise.

getShortVolatile

short getShortVolatile(int index)

Get the value at a given index with volatile semantics.

Parameters:

index - The index in bytes from where to get the value.

Returns:

The value retrieved from the given index.

putShortVolatile
