Constructor Detail

ArrayWriter

public ArrayWriter()

Initializes a new instance of the com.upokecenter.ArrayWriter class with a default buffer size.

ArrayWriter

public ArrayWriter(int initialSize)

Initializes a new instance of the com.upokecenter.ArrayWriter class with the given initial buffer size.

Parameters:

initialSize - The parameter initialSize is a 32-bit signed integer.

Method Detail

Clear

public void Clear()

Offers a fast way to reset the length of the array writer's data to 0.

ToArray

public byte[] ToArray()

Generates an array of all bytes written so far to it.

Returns:

A byte array.

write

public void write(int byteValue)

Writes an 8-bit byte to the array.

Specified by:

write in interface IByteWriter

Parameters:

byteValue - An integer containing the byte to write. Only the lower 8 bits of this value will be used.

write

public void write(byte[] src,
                  int offset,
                  int length)

Writes a series of bytes to the array.

Specified by:

write in interface IWriter

Parameters:

src - Byte array containing the data to write.

offset - A zero-based index showing where the desired portion of src begins.

length - The number of elements in the desired portion of src (but not more than src 's length).

Throws:

NullPointerException - The parameter src is null.

IllegalArgumentException - Either offset or length is less than 0 or greater than src 's length, or src ' s length minus offset is less than length.
