Method Details

New

public static VarByte New()

New

public static VarByte New(int initialCapacity)

Use this constructor only if really a specific size is needed or list of bytes to be handled is huge.
Otherwise, use the factory methods as they are faster due to skipping capacity checks and bounds adjustment.

Note that the given initialCapacity will still be adjusted to the next higher 2^n bounding value.

Parameters:

initialCapacity - the initial size of the buffer

Returns:

a new VarByte instance

get

public byte get(int index)

lastByte

public byte lastByte()

firstByte

Specified by:

readExternal in interface Externalizable

Throws:

IOException

ClassNotFoundException

Parameters:

printStream - the PrintStream instance to be written to.

Returns:

this VarByte instance.

printTo

public VarByte printTo(PrintStream printStream)

Passes a copy of the internal byte array to the PrintStream.print(String) method of the passed PrintStream instance.

Parameters:

printStream - the PrintStream instance to be written to.

Returns:

this VarByte instance.
