Method Detail

getBuffer

public byte[] getBuffer()

Gets the backing byte array. The capacity of the array may be much larger than the size of its contents. Use getBufferSize() for the size.

Returns:

The backing byte array.

getBufferSize

public int getBufferSize()

Returns the amount of data in the byte array.

Returns:

The amount of data in the byte array.

getBufferCapacity

public int getBufferCapacity()

Returns the capacity of the backing byte array. This may grow dynamically as needed.

Returns:

The capacity of the backing byte array.

clear

public void clear()

Sets the size of the byte array to 0. The capacity remains unchanged.

appendByte

public void appendByte(byte aByte)

Append a byte to the byte array. This may cause a reallocation if there is not enough space.

Parameters:

aByte - The byte to append to the array.

appendBytes

public void appendBytes(byte[] bytes)

Appends a byte array to the byte array. This may cause a reallocation if there is not enough space.

Parameters:

bytes - The bytes to append to the array.

appendBytes

public void appendBytes(byte[] bytes,
                        int offset,
                        int length)

Appends data from a byte array to the byte array. This may cause a reallocation if there is not enough space.

Parameters:

bytes - The bytes to append to the array.

offset - Beginning offset to start copying from.

length - Number of bytes to copy.

appendString

public void appendString(String str)

Appends data from a string to the byte array. This is a faster more efficient way of appending a String than appendBytes(str.getBytes());

Parameters:

str - The string to append.

realloc

public void realloc(int size)

Reallocates the byte array if more space is needed.

Parameters:

size - parameter

toString

public String toString()

Overrides:

toString in class Object
