    • Method Detail

      • get

        byte[] get​(byte[] key)
        Gets the byte array associated with key, or none if this key is not present.
        Specified by:
        get in interface IOByteArrayMap

      • put

        void put​(byte[] key,
         byte[] value)
        Associates the byte[] key with the byte[] value in the hash. If key is already present in the map, the old value associated with it is replaced by value.
        Specified by:
        put in interface IOByteArrayMap

      • putNoReplace

        boolean putNoReplace​(byte[] key,
                     byte[] value)
        Associates the byte[] key with the byte[] value in the hash. Fails (and returns false) if key is already present in the map.
        Specified by:
        putNoReplace in interface IOByteArrayMap

      • remove

        boolean remove​(byte[] key)
        Removes the key, value pair whose key is the argument.
        Specified by:
        remove in interface IOByteArrayMap

      • containsKey

        boolean containsKey​(byte[] key)
        Returns true iff key is present.
        Specified by:
        containsKey in interface IOByteArrayMap

      • keys

        IOByteArrayEnumeration keys()
        Returns a list of all keys in the hash, provided no inserts or deletes are made while the Enumeration is untraversed. If inserts or deletes are made. the behavior is undefined.
        Specified by:
        keys in interface IOByteArrayMap

      • mkeys

        ByteArrayEnumeration mkeys()
        returns a simple Enumeration (that does not throw IOExceptions)
