Class Bytes

java.lang.Object

com.google.crypto.tink.util.Bytes

@Immutable
public final class Bytes
extends Object

Immutable Wrapper around a byte array.

Wrap a bytearray so it prevents callers from modifying its contents. It does this by making a copy upon initialization, and also makes a copy if the underlying bytes are requested.

Since:

1.0.0

Method Detail

copyFrom

public static Bytes copyFrom(byte[] data)

Parameters:

data - the byte array to be wrapped.

Returns:

an immutable wrapper around the provided bytes.

copyFrom

public static Bytes copyFrom(byte[] data,
                             int start,
                             int len)

Wrap an immutable byte array over a slice of a Bytes

Parameters:

data - the byte array to be wrapped.

start - the starting index of the slice

len - the length of the slice. start + len must be less than the length of the array.

Returns:

an immutable wrapper around the bytes in the slice from start to start + len

toByteArray

public byte[] toByteArray()

Returns:

a copy of the bytes wrapped by this object.

size

public int size()

Returns:

the length of the bytes wrapped by this object.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
