Buffer(int size)

Method Summary

Modifier and Type	Method and Description
static int	asciiSizeInBytes(long v) Binary search for character width which favors matching lower numbers.
byte[]	toByteArray()
static int	varintSizeInBytes(int value) A base 128 varint encodes 7 bits at a time, this checks how many bytes are needed to represent the value.
static int	varintSizeInBytes(long v) Like varintSizeInBytes(int), except for uint64.
Buffer	write(byte[] v)
Buffer	writeAscii(long v)
Buffer	writeAscii(String v)
Buffer	writeByte(int v)
Buffer	writeUtf8(String string) This transcodes a UTF-16 Java String to UTF-8 bytes.

Method Detail

writeByte

public Buffer writeByte(int v)

write

public Buffer write(byte[] v)

writeAscii

public Buffer writeAscii(String v)

writeUtf8

public Buffer writeUtf8(String string)

This transcodes a UTF-16 Java String to UTF-8 bytes.

This looks most similar to io.netty.buffer.ByteBufUtil.writeUtf8(AbstractByteBuf, int, CharSequence, int) v4.1, modified including features to address ASCII runs of text.

asciiSizeInBytes

public static int asciiSizeInBytes(long v)

Binary search for character width which favors matching lower numbers.

Adapted from okio.Buffer

writeAscii

public Buffer writeAscii(long v)

varintSizeInBytes

public static int varintSizeInBytes(int value)

A base 128 varint encodes 7 bits at a time, this checks how many bytes are needed to represent the value.

See https://developers.google.com/protocol-buffers/docs/encoding#varints

This logic is the same as com.squareup.wire.ProtoWriter.varint32Size v2.3.0 which benchmarked faster than loop variants of the frequently copy/pasted VarInt.varIntSize

varintSizeInBytes

public static int varintSizeInBytes(long v)

Like varintSizeInBytes(int), except for uint64.

toByteArray

public byte[] toByteArray()
