Constructor Detail

ByteBigArray

public ByteBigArray()

Creates a new big array containing one initial segment

ByteBigArray

public ByteBigArray(byte initialValue)

Method Detail

sizeOf

public long sizeOf()

Returns the size of this big array in bytes.

get

public byte 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,
                byte value)

Sets the element of this big array at specified index.

Parameters:

index - a position in this big array.

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(byte value)

Fills the entire big array with the specified value.

copyTo

public void copyTo(long sourceIndex,
                   ByteBigArray 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.
