This method can be repeatedly called.
Nulls and empty sketches are ignored.

This method can be repeatedly called.
Nulls and empty sketches are ignored.

datum - The given double datum.public abstract void update(String datum)
Note: this will not produce the same output hash values as the update(char[])
method and will generally be a little slower depending on the complexity of the UTF8 encoding.
Note: this is not a Sketch Union operation. This treats the given string as a data item.
datum - The given String.public abstract void update(byte[] data)
Note: this is not a Sketch Union operation. This treats the given byte array as a data item.
data - The given byte array.public abstract void update(ByteBuffer data)
Note: this is not a Sketch Union operation. This treats the given ByteBuffer as a data item.
data - The given ByteBuffer.public abstract void update(int[] data)
Note: this is not a Sketch Union operation. This treats the given integer array as a data item.
data - The given int array.public abstract void update(char[] data)
Note: this will not produce the same output hash values as the update(String)
method but will be a little faster as it avoids the complexity of the UTF8 encoding.
Note: this is not a Sketch Union operation. This treats the given char array as a data item.
