ObservableIntegerArray is a int[] array that allows listeners to track changes when they occur. In order to track changes, the internal array is encapsulated and there is no direct access available from the outside. Bulk operations are supported but they always do a copy of the data range.

Since:

JavaFX 8.0

Method Detail

copyTo

void copyTo(int srcIndex,
            int[] dest,
            int destIndex,
            int length)

Copies specified portion of array into dest array. Throws the same exceptions as System.arraycopy() method.

Parameters:

srcIndex - starting position in the observable array

dest - destination array

destIndex - starting position in destination array

length - length of portion to copy

copyTo

void copyTo(int srcIndex,
            ObservableIntegerArray dest,
            int destIndex,
            int length)

Copies specified portion of array into dest observable array. Throws the same exceptions as System.arraycopy() method.

Parameters:

srcIndex - starting position in the observable array

dest - destination observable array

destIndex - starting position in destination observable array

length - length of portion to copy

get

int get(int index)

Gets a single value of array. This is generally as fast as direct access to an array and eliminates necessity to make a copy of array.

Parameters:

index - index of element to get

Returns:

value at the given index

Throws:

ArrayIndexOutOfBoundsException - if index is outside array bounds

addAll

void addAll(int... elements)

Appends given elements to the end of this array. Capacity is increased if necessary to match the new size of the data.

Parameters:

elements - elements to append

addAll

void addAll(ObservableIntegerArray src)

Appends content of a given observable array to the end of this array. Capacity is increased if necessary to match the new size of the data.

Parameters:

src - observable array with elements to append

addAll

void addAll(int[] src,
            int srcIndex,
            int length)

Appends a portion of given array to the end of this array. Capacity is increased if necessary to match the new size of the data.

Parameters:

src - source array

srcIndex - starting position in source array

length - length of portion to append

addAll

void addAll(ObservableIntegerArray src,
            int srcIndex,
            int length)

Appends a portion of given observable array to the end of this array. Capacity is increased if necessary to match the new size of the data.

Parameters:

src - source observable array

srcIndex - starting position in source array

length - length of portion to append

setAll

void setAll(int... elements)

Replaces this observable array content with given elements. Capacity is increased if necessary to match the new size of the data.

Parameters:

elements - elements to put into array content

Throws:

NullPointerException - if src is null

setAll

void setAll(int[] src,
            int srcIndex,
            int length)

Replaces this observable array content with a copy of portion of a given array. Capacity is increased if necessary to match the new size of the data.

Parameters:

src - source array to copy.

srcIndex - starting position in source observable array

length - length of a portion to copy

Throws:

NullPointerException - if src is null

setAll

void setAll(ObservableIntegerArray src)

Replaces this observable array content with a copy of given observable array. Capacity is increased if necessary to match the new size of the data.

Parameters:

src - source observable array to copy.

Throws:

NullPointerException - if src is null

setAll

void setAll(ObservableIntegerArray src,
            int srcIndex,
            int length)

Replaces this observable array content with a portion of a given observable array. Capacity is increased if necessary to match the new size of the data.

Parameters:

src - source observable array to copy.

srcIndex - starting position in source observable array

length - length of a portion to copy

Throws:

NullPointerException - if src is null

set

void set(int destIndex,
         int[] src,
         int srcIndex,
         int length)

Copies a portion of specified array into this observable array. Throws the same exceptions as System.arraycopy() method.

Parameters:

destIndex - the starting destination position in this observable array

src - source array to copy

srcIndex - starting position in source array

length - length of portion to copy

set

void set(int destIndex,
         ObservableIntegerArray src,
         int srcIndex,
         int length)

Copies a portion of specified observable array into this observable array. Throws the same exceptions as System.arraycopy() method.

Parameters:

src - source observable array to copy

srcIndex - starting position in source array

length - length of portion to copy

set

void set(int index,

Sets a single value in the array. Avoid using this method if many values are updated, use #setAll(int, int[], int, int) update method instead with as minimum number of invocations as possible.

Parameters:

index - index of the value to set

value - new value for the given index

Throws:

ArrayIndexOutOfBoundsException - if index is outside array bounds

toArray

int[] toArray(int[] dest)

Returns an array containing copy of the observable array. If the observable array fits in the specified array, it is copied therein. Otherwise, a new array is allocated with the size of the observable array.

Parameters:

dest - the array into which the observable array to be copied, if it is big enough; otherwise, a new int array is allocated. Ignored, if null.

Returns:

an int array containing the copy of the observable array

toArray

              int[] dest,
              int length)

Returns an array containing copy of specified portion of the observable array. If specified portion of the observable array fits in the specified array, it is copied therein. Otherwise, a new array of given length is allocated.

Parameters:

srcIndex - starting position in the observable array
