sealed class ByteSequence : Comparable<ByteSequence>
An abstraction of a byte array, with offset and size that does no copying of bytes unless asked to.
The data of interest typically starts at position offset within the bytes and is size bytes long.
abstract val bytes: ByteArray
The underlying bytes. Some implementations may choose to make a copy of the underlying ByteArray for security reasons. For example, OpaqueBytes. |
|
val offset: Int
The start position of the sequence within the byte array. |
|
val size: Int
The number of bytes this sequence represents. |
open fun compareTo(other: ByteSequence): Int
Compare byte arrays byte by byte. Arrays that are shorter are deemed less than longer arrays if all the bytes of the shorter array equal those in the same position of the longer array. |
|
fun copy(): ByteSequence
Copy this sequence, complete with new backing array. This can be helpful to break references to potentially large backing arrays from small sub-sequences. |
|
fun copyBytes(): ByteArray
Same as copy but returns just the new byte array. |
|
open fun equals(other: Any?): Boolean |
|
open fun hashCode(): Int |
|
fun open(): ByteArrayInputStream
Returns a ByteArrayInputStream of the bytes. |
|
fun putTo(buffer: ByteBuffer): ByteBuffer
Write this sequence to a ByteBuffer. |
|
fun slice(start: Int = 0, end: Int = size): ByteBuffer
A new read-only ByteBuffer view of this sequence or part of it. If start or end are negative then IllegalArgumentException is thrown, otherwise they are clamped if necessary. This method cannot be used to get bytes before offset or after offset+size, and never makes a new array. |
|
fun subSequence(offset: Int, size: Int): ByteSequence
Create a sub-sequence of this sequence. A copy of the underlying array may be made, if a subclass overrides bytes to do so, as OpaqueBytes does. |
|
fun take(n: Int): ByteSequence
Take the first n bytes of this sequence as a sub-sequence. See subSequence for further semantics. |
|
open fun toString(): String |
|
fun writeTo(output: OutputStream): Unit
Write this sequence to an OutputStream. |
fun of(bytes: ByteArray, offset: Int = 0, size: Int = bytes.size): ByteSequence
Construct a ByteSequence given a ByteArray and optional offset and size, that represents that potentially sub-sequence of bytes. |
fun Any.contextLogger(): <ERROR CLASS>
When called from a companion object, returns the logger for the enclosing class. |
|
fun <T : Any> ByteSequence.deserialize(serializationFactory: SerializationFactory = SerializationFactory.defaultFactory, context: SerializationContext = serializationFactory.defaultContext): T
Convenience extension method for deserializing a ByteSequence, utilising the defaults. |
|
fun <T : Any> ByteSequence.deserializeWithCompatibleContext(serializationFactory: SerializationFactory = SerializationFactory.defaultFactory, context: SerializationContext = serializationFactory.defaultContext): ObjectWithCompatibleContext<T>
Additionally returns SerializationContext which was used for encoding. It might be helpful to know SerializationContext to use the same encoding in the reply. |
open class OpaqueBytes : ByteSequence
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 won't arrive for a few years yet! |

class OpaqueBytesSubSequence : ByteSequence
Class is public for serialization purposes. |
