# OpaqueBytes

`open class OpaqueBytes`

A simple class that wraps a byte array and makes the equals/hashCode/toString methods work as you actually expect. In an ideal JVM this would be a value type and be completely overhead free. Project Valhalla is adding such functionality to Java, but it wont arrive for a few years yet

### Constructors

<init> | `OpaqueBytes(bits: ByteArray)` A simple class that wraps a byte array and makes the equals/hashCode/toString methods work as you actually expect. In an ideal JVM this would be a value type and be completely overhead free. Project Valhalla is adding such functionality to Java, but it wont arrive for a few years yet

### Properties

bits | `val bits: ByteArray`
size | `val size: Int`

### Functions

equals | `open fun equals(other: Any?): Boolean`
hashCode | `open fun hashCode(): Int`
toString | `open fun toString(): String`

### Companion Object Functions

of | `fun of(vararg b: Byte): OpaqueBytes`

### Extension Functions

deserialize | `fun <T : Any> OpaqueBytes.deserialize(kryo: <ERROR CLASS> = THREAD_LOCAL_KRYO.get()): T`
sha256 | `fun OpaqueBytes.sha256(): SHA256`

### Inheritors

DigitalSignature | `open class DigitalSignature : OpaqueBytes` A wrapper around a digital signature. The covering field is a generic tag usable by whatever is interpreting the signature. It isnt used currently, but experience from Bitcoin suggests such a feature is useful, especially when building partially signed transactions.
SecureHash | `sealed class SecureHash : OpaqueBytes`
SerializedBytes | `class SerializedBytes<T : Any> : OpaqueBytes` A type safe wrapper around a byte array that contains a serialised object. You can call SerializedBytes.deserialize to get the original object back.
