Field Detail

OUTER

public static final Coder.Context OUTER

The outer context: the value being encoded or decoded takes up the remainder of the record/stream contents.

NESTED

public static final Coder.Context NESTED

The nested context: the value being encoded or decoded is (potentially) a part of a larger record/stream contents, and may have other parts encoded or decoded after it.

isWholeStream

public final boolean isWholeStream

Whether the encoded or decoded value fills the remainder of the output or input (resp.) record/stream contents. If so, then the size of the decoded value can be determined from the remaining size of the record/stream contents, and so explicit lengths aren't required.
