Constructor Details

ObjectBigArray

public ObjectBigArray()

Creates a new big array containing one initial segment

ObjectBigArray

public ObjectBigArray(Object initialValue)

Method Details

getCapacity

public long getCapacity()

Returns the current available capacity in this array

sizeOf

public long sizeOf()

Returns the size of this big array in bytes.

get

public T get(long index)

Returns the element of this big array at specified index.

Parameters:

index - a position in this big array.

Returns:

the element of this big array at the specified position.

set

public void set(long index,
 T value)

Sets the element of this big array at specified index.

Parameters:

index - a position in this big array.

getAndSet

public T getAndSet(long index,
 T value)

Sets the element of this big array at the specified index, returning the previous element at that index

Parameters:

index - a position in this big array

value - the new value to store at the specified position

Returns:

the previous element at the specified position

replace

public boolean replace(long index,
 T value)

Replaces the element of this big array at specified index.

Parameters:

index - a position in this big array.

Returns:

true if the previous value was not null

ensureCapacity

public void ensureCapacity(long length)

Ensures this big array is at least the specified length. If the array is smaller, segments are added until the array is larger then the specified length.

fill

public void fill(T value)

Fills the entire big array with the specified value.

copyTo

public void copyTo(long sourceIndex,
 ObjectBigArray<T> destination,
 long destinationIndex,
 long length)

Copies this array, beginning at the specified sourceIndex, to the specified destinationIndex of the destination array. A subsequence of this array's components are copied to the destination array referenced by destination. The number of components copied is equal to the length argument. The components at positions sourceIndex through sourceIndex+length-1 in this array are copied into positions destinationIndex through destinationIndex+length-1, respectively, of the destination array.
