Interface PackInput

All Known Implementing Classes:

ChunkedInput, PackedInputArray

public interface PackInput

This is what PackStream uses to ingest data, implement this on top of any data source of your choice to deserialize the stream with PackStream.

byte	readByte() Consume one byte
PackInput	readBytes(byte[] into, int offset, int toRead) Consume a specified number of bytes
double	readDouble() Consume an 8-byte IEEE 754 "double format" floating-point number
int	readInt() Consume a 4-byte signed integer
long	readLong() Consume an 8-byte signed integer
short	readShort() Consume a 2-byte signed integer
