Direct Known Subclasses:

MemoHash, MemoId, MemoNone, MemoReturnHash, MemoText

public abstract class Memo
extends Object

The memo contains optional extra information. It is the responsibility of the client to interpret this value. Memos can be one of the following types:

• MEMO_NONE: Empty memo.
• MEMO_TEXT: A string up to 28-bytes long.
• MEMO_ID: A 64 bit unsigned integer.
• MEMO_HASH: A 32 byte hash.
• MEMO_RETURN: A 32 byte hash intended to be interpreted as the hash of the transaction the sender is refunding.

Use static methods to generate any of above types.
