Method Detail

isCopy

public final boolean isCopy()

Specified by:

isCopy in interface IHasByteArray

Returns:

true if the contained byte array was copied in the constructor or not.

bytes

@Nonnull
 @ReturnsMutableObject
public final byte[] bytes()

Specified by:

bytes in interface IHasByteArray

Returns:

A reference to the contained byte array. Gives write access to the payload! Never null.

getOffset

@Nonnegative
public final int getOffset()

Specified by:

getOffset in interface IHasByteArray

Returns:

The offset into the byte array to start reading. This is always 0 when copied. Must be ge; 0.

IHasByteArray.bytes(), IHasSize.size()

size

@Nonnegative
public final int size()

Specified by:

size in interface IHasSize

Returns:

The number of contained elements. Always ≥ 0.

toString

public String toString()

Overrides:

toString in class Object
