public abstract class AbstractLazyEncodedByteArray
extends AbstractLazyEncodedDataObject<byte[]>

Class AbstractLazyEncodedByteArray represents a DataObject in which the state is represented in an encoded form or a decoded form, with conversions between the two forms done lazily (when first needed). The encoded form is a byte array. Having a decoded representation of the state is convenient if the positions of fields in the encoded representation can vary depending on the values of other fields that might not have been supplied yet. For example, the presence/absence of optional fields, and the lengths of variable-length fields, can both affect the positions of later fields. Once an object has been marked read-only, both encoded and decoded forms can co-exist.

All subclasses should define static int getContainedLength(byte[] data, int start, int len) and use it in decode() to ensure that the contained value exactly fills the array.

Constructor Detail

AbstractLazyEncodedByteArray

protected AbstractLazyEncodedByteArray()

Constructs a new AbstractLazyEncodedByteArray with no field values.

AbstractLazyEncodedByteArray

protected AbstractLazyEncodedByteArray(byte[] data)

Constructs a new AbstractLazyEncodedByteArray object from network-encoded data. The state is in the encoded form: it is not decoded and might not be decodable.

Parameters:

data - network-encoded data

Throws:

java.lang.NullPointerException - if data is null

AbstractLazyEncodedByteArray

protected AbstractLazyEncodedByteArray(byte[] data,
                            int start,
                            int len)

Constructs a new AbstractLazyEncodedByteArray from part of given network-encoded data. The part starts at index start and is len bytes long. The state is in the encoded form: it is not decoded and might not be decodable.

Parameters:

data - network-encoded data

start - starting offset of network-encoded data

len - length of encoded part in bytes

Throws:

java.lang.NullPointerException - if data is null

java.lang.IllegalArgumentException - if len is negative

java.lang.ArrayIndexOutOfBoundsException - if the part is not within the data
