ByteBuffer

open class ByteBuffer : Comparable<ByteBuffer>

Types

object Companion

Properties

var bigEndian: Boolean

The byte order. Defaults to BIG_ENDIAN.

val capacity: Int

The fixed capacity of this ByteBuffer.

The limit, i.e. the upper bound (exclusive) for read/writes.

nativeByteOrder

var nativeByteOrder: Boolean

var position: Int

The current position. Must be between 0 and limit.

Functions

fun array(): ByteArray

port of java.nio.ByteBuffer.array() Returns byte array that backs this buffer.

fun arrayOffset(): Int

Returns the offset within this buffer's backing array of the first element of the buffer (optional operation).

fun asFloatBuffer(): FloatBuffer

Creates a view of this byte buffer as a float buffer.

fun asIntBuffer(): IntBuffer

fun asLongBuffer(): LongBuffer

Creates a view of this byte buffer as a long buffer.

asReadOnlyBuffer

fun asReadOnlyBuffer(): ByteBuffer

Creates a new, read-only byte buffer that shares this buffer's content.

fun clear(): ByteBuffer

Clears the buffer: sets position to 0, limit to capacity, and mark to -1.

fun compact(): ByteBuffer

Compacts this buffer (optional operation).

open operator override fun compareTo(other: ByteBuffer): Int

Compares the remaining bytes lexicographically.

fun duplicate(): ByteBuffer

Creates a new buffer that shares this buffer’s content but has independent position, limit, and mark.

open operator override fun equals(other: Any?): Boolean

fun flip(): ByteBuffer

Flips the buffer: sets limit to current position and resets position to 0.

fun get(): Byte

Relative get: reads the byte at the current position then increments it.

fun get(index: Int): Byte

Absolute get: returns the byte at the given index (without modifying position).

fun get(dst: ByteArray, offset: Int = 0, length: Int = dst.size - offset): ByteBuffer

Bulk get: transfers remaining bytes into the given destination array.

open fun get(index: Int, dst: ByteArray, offset: Int, length: Int): ByteBuffer

Absolute bulk get method.

fun getInt(): Int

Relative get method for reading an int value.

fun getInt(index: Int): Int

Absolute get method for reading an int value.

fun getLong(): Long

Relative get method for reading a long value.

fun getLong(index: Int): Long

Absolute get method for reading a long value.

fun getShort(): Short

Relative get method for reading a short value.

fun getShort(index: Int): Short

Absolute get method for reading a short value.

fun hasArray(): Boolean

Tells whether or not this buffer is backed by an accessible byte array. For this implementation, we always return true since we can always create and return a byte array copy of the buffer contents.

open override fun hashCode(): Int

fun hasRemaining(): Boolean

Tells whether there are any elements between the current position and the limit.

fun isReadOnly(): Boolean

true if mutation is disallowed

fun limit(newLimit: Int): ByteBuffer

Sets this buffer's limit.

fun mark(): ByteBuffer

Sets the mark at the current position.

fun order(): ByteOrder

Returns this buffer’s current byte order.

fun order(bo: ByteOrder): ByteBuffer

Modifies this buffer's byte order.

fun position(newPosition: Int): ByteBuffer

Sets this buffer's position. If the mark is defined and larger than the new position then it is discarded.

fun put(b: Byte): ByteBuffer

Relative put: writes a byte at the current position then increments it.

fun put(src: ByteBuffer): ByteBuffer

Relative bulk put method (optional operation).

fun put(index: Int, b: Byte): ByteBuffer

Absolute put: writes a byte at the specified index.

fun put(src: ByteArray, offset: Int = 0, length: Int = src.size - offset): ByteBuffer

Bulk put: transfers bytes from the source array into this buffer.

fun putBuffer(pos: Int, src: ByteBuffer, srcPos: Int, n: Int)

fun putInt(value: Int): ByteBuffer

Relative put method for writing an int value (optional operation).

fun putLong(value: Long): ByteBuffer

fun putShort(value: Short): ByteBuffer

Relative put method for writing a short value (optional operation).

fun remaining(): Int

Returns the number of bytes remaining between position and limit.

fun reset(): ByteBuffer

Resets the position to the previously set mark.

fun rewind(): ByteBuffer

Rewinds the buffer: resets position to 0 without changing limit.

fun slice(): ByteBuffer

Creates a new buffer that is a view of this buffer's content between position and limit.

open override fun toString(): String
