Method Detail

getHash

public byte[] getHash()

Description copied from interface: Binary

Get the SHA-1 hash of the contents. This hash can be used to determine whether two Binary instances contain the same content.

Repeatedly calling this method should generally be efficient, as it most implementations will compute the hash only once.

Overrides:

getHash in class AbstractBinary

Returns:

the hash of the contents as a byte array, or an empty array if the hash could not be computed.

See Also:

MessageDigest.digest(byte[]), MessageDigest.getInstance(String), Binary.getHexHash()

getHexHash

public String getHexHash()

Description copied from interface: Binary

Get the hexadecimal form of the SHA-1 hash of the contents. This hash can be used to determine whether two Binary instances contain the same content.

Repeatedly calling this method should generally be efficient, as it most implementations will compute the hash only once.

Overrides:

getHexHash in class AbstractBinary

Returns:

the hexadecimal form of the Binary.getHash(), or a null string if the hash could not be computed or is not known
