public abstract class AbstractLazyEncodedNamedInteger<T extends NamedInteger>
extends AbstractLazyEncodedDataObject<T>

Class AbstractLazyEncodedNamedInteger represents a NamedInteger in which bit-fields within the named integer are also represented in a decoded form, with conversions between the two forms done lazily (when first needed). 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.

Constructor Detail

AbstractLazyEncodedNamedInteger

protected AbstractLazyEncodedNamedInteger()

Constructs a new AbstractLazyEncodedNamedInteger with no field values.

AbstractLazyEncodedNamedInteger

protected AbstractLazyEncodedNamedInteger(byte[] data)

Constructs a new AbstractLazyEncodedNamedInteger 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:

NullPointerException - if data is null

AbstractLazyEncodedNamedInteger

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

Constructs a new AbstractLazyEncodedNamedInteger 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 data in bytes

Throws:

NullPointerException - if data is null

IllegalArgumentException - if len is negative

ArrayIndexOutOfBoundsException - if the part is not within the data

Method Detail

fromValue

protected abstract T fromValue(int value)

Converts an int to a NamedInteger. Reuses any existing instance where possible.

Parameters:

value - int

Returns:

T extends NamedInteger
