Class ExchangeCodec

  • public abstract class ExchangeCodec
extends java.lang.Object
    Utility class provides methods to convert exchange code from string to long and vice versa.

    Methods are thread-safe and longToCode(long) caches strings internally to optimise string allocations. From the other side, synchronized methods may be too slow for scenarios, when they are used frequently. Consider using of AlphanumericCodec instance in this case.

    If you not sure a name is less or equal to 10 characters and all of the characters are uppercase, use codeToLongSafely(java.lang.String). It truncates the name if its length is more than 10 characters and converts the name to uppercase. For example, the name "GoldmanSachs" will be converted to "GOLDMANSAC" before encoded.
