PgByteWriter

class PgByteWriter(initialCapacity: Int = 1024, maxCapacity: Int = 65536)

Optimized buffer for building binary packets for the database. Allows reserving space for size and filling it later without memory copying.

Functions

clear

fun clear()

fillLengthInt

fun fillLengthInt(markerIndex: Int)

Calculates the number of bytes added since reserveLengthInt was called and writes this value at the marker. Does not include the 4 bytes of the marker itself (in accordance with many PG structures).

reserveLengthInt

fun reserveLengthInt(): Int

Leaves 4 bytes of space for a number (e.g. packet size) and returns the index where this size should be written later.

toByteArray

fun toByteArray(): ByteArray

updatePosition

fun updatePosition(newPosition: Int)

writeByte

fun writeByte(b: Byte)

writeBytes

fun writeBytes(bytes: ByteArray)

writeDouble

fun writeDouble(d: Double)

writeFloat

fun writeFloat(f: Float)

writeInt

fun writeInt(i: Int)

writeLong

fun writeLong(l: Long)

writeShort

fun writeShort(s: Short)
