getHash

public byte[] getHash()

Get the hash of the content read by this stream. This method will return null if the stream has not yet been closed.

Returns:

the hash of the contents as a byte array, or null if the stream has not yet been closed

getHashAsHexString

public String getHashAsHexString()
