Constructor Detail

ByteVector

public ByteVector()
Construct byte vector instance with default block size.


ByteVector

public ByteVector(int capacity)
Construct byte vector instance.

Parameters:
capacity - initial block size

ByteVector

public ByteVector(byte[] a)
Construct byte vector instance.

Parameters:
a - byte array to use TODO should n should be initialized to a.length to be consistent with CharVector behavior? [GA]

ByteVector

public ByteVector(byte[] a,
                  int capacity)
Construct byte vector instance.

Parameters:
a - byte array to use
capacity - initial block size TODO should n should be initialized to a.length to be consistent with CharVector behavior? [GA]
Method Detail

getArray

public byte[] getArray()
Obtain byte vector array.

Returns:
byte array

length

public int length()
Obtain number of items in array.

Returns:
number of items

capacity

public int capacity()
Obtain capacity of array.

Returns:
current capacity of array

put

public void put(int index,
                byte val)
Pet byte at index.

Parameters:
index - the index
val - a byte

get

public byte get(int index)
Get byte at index.

Parameters:
index - the index
Returns:
a byte

alloc

public int alloc(int size)
This is to implement memory allocation in the array. Like malloc().

Parameters:
size - to allocate
Returns:
previous length

trimToSize

public void trimToSize()
