  The context in which encoding or decoding is being done.

• • Field Summary

    Fields 

    Modifier and Type	Field and Description
    boolean	isWholeStream Whether the encoded or decoded value fills the remainder of the output or input (resp.) record/stream contents.
    static 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.
    static Coder.Context	OUTER The outer context: the value being encoded or decoded takes up the remainder of the record/stream contents.

    • 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.
