get
public MessageDigestCalculatingInputStream get() throws java.io.IOException
Constructs a new instance.This builder use the aspects InputStream, OpenOption[], and MessageDigest.
You must provide an origin that can be converted to an InputStream by this builder, otherwise, this call will throw an
UnsupportedOperationException
.- Returns:
- a new instance.
- Throws:
java.lang.UnsupportedOperationException
- if the origin cannot provide an InputStream.java.io.IOException
- if an I/O error occurs.- See Also:
AbstractStreamBuilder.getInputStream()
-
setMessageDigest
public void setMessageDigest(java.security.MessageDigest messageDigest)
Sets the message digest.- Parameters:
messageDigest
- the message digest.
-
setMessageDigest
public void setMessageDigest(java.lang.String algorithm) throws java.security.NoSuchAlgorithmException
Sets the name of the name of the message digest algorithm.- Parameters:
algorithm
- the name of the algorithm. See the MessageDigest section in the Java Cryptography Architecture Standard Algorithm Name Documentation for information about standard algorithm names.- Throws:
java.security.NoSuchAlgorithmException
- if no Provider supports a MessageDigestSpi implementation for the specified algorithm.
