      • ByteArrayHashMap

        public ByteArrayHashMap​(int initialCapacity,
                        float loadFactor,
                        RowMetaInterface keyMeta)
        Constructs an empty ByteArrayHashMap with the specified initial capacity and load factor.
        Parameters:
        initialCapacity - the initial capacity
        loadFactor - the load factor
        Throws:
        IllegalArgumentException - if the initial capacity is negative or the load factor is nonpositive

      • ByteArrayHashMap

        public ByteArrayHashMap​(int initialCapacity,
                        RowMetaInterface keyMeta)
        Constructs an empty ByteArrayHashMap with the specified initial capacity and the default load factor (0.75).
        Parameters:
        initialCapacity - the initial capacity.
        Throws:
        IllegalArgumentException - if the initial capacity is negative.

      • ByteArrayHashMap

        public ByteArrayHashMap​(RowMetaInterface keyMeta)
        Constructs an empty HashMap with the default initial capacity (16) and the default load factor (0.75).

      • isEqualValue

      • equalsByteArray

        public final boolean equalsByteArray​(byte[] value,

      • get

        public byte[] get​(byte[] key)
        Returns the entry to which the specified key is "mapped", or, in other words, if this index contains an entry that is equal to the given key, or null if this is not the case.

        More formally, if this index contains an entry e such that key.equals(e)), then this method returns e; otherwise it returns null. (There can be at most one such entry.)

        Parameters:
        key - The key to look up.
        Throws:
        KettleValueException - in case of a value conversion error
