byte[] getHash()
Repeatedly calling this method should generally be efficient, as it most implementations will compute the hash only once.
MessageDigest.digest(byte[])
,
MessageDigest.getInstance(String)
,
getHexHash()
String getHexHash()
Repeatedly calling this method should generally be efficient, as it most implementations will compute the hash only once.
getHash()
, or a null string if the hash could not be computed or is not knownMessageDigest.digest(byte[])
,
MessageDigest.getInstance(String)
,
getHash()
String getMimeType() throws IOException, RepositoryException
IOException
- if there is a problem reading the binary content
RepositoryException
- if an error occurs.String getMimeType(String name) throws IOException, RepositoryException
name
- the name of the binary value, useful in helping to determine the MIME type
IOException
- if there is a problem reading the binary content
RepositoryException
- if an error occurs.
