ZeroCopyInputStream-class {RProtoBuf}

Virtual Class "ZeroCopyInputStream"

Description

R wrapper for the ZeroCopyInputStream c++ class

Objects from the Class

This is a virtual class

Slots

pointer:

external pointer to the google::protobuf::io::ZeroCopyInputStream object

Methods

$

signature(x="ZeroCopyInputStream"): invokes a method

Next

signature(object="ZeroCopyInputStream"): Get a number of bytes from the stream as a raw vector.

Skip

signature(object="ZeroCopyInputStream"): skip a number of bytes

BackUp

signature(object="ZeroCopyInputStream"): Backs up a number of bytes, so that the next call to Next returns data again that was already returned by the last call to Next.

ByteCount

signature(object="ZeroCopyInputStream"): Returns the total number of bytes read since this object was created.

ReadRaw

signature(object="ZeroCopyInputStream", size = "integer"): read raw bytes from the stream

ReadRaw

signature(object="ZeroCopyInputStream", size = "numeric"): read raw bytes from the stream

ReadString

signature(object="ZeroCopyInputStream", size = "integer"): same as ReadRaw but formats the result as a string

ReadString

signature(object="ZeroCopyInputStream", size = "numeric"): same as ReadRaw but formats the result as a string

ReadVarint32

signature(object="ZeroCopyInputStream"): Read an unsigned integer with Varint encoding, truncating to 32 bits.

ReadLittleEndian32

signature(object="ZeroCopyInputStream"): Read a 32-bit little-endian integer.

ReadLittleEndian64

signature(object="ZeroCopyInputStream"): Read a 64-bit little-endian integer. In R the value is stored as a double which looses some precision (no other way)

ReadVarint64

signature(object="ZeroCopyInputStream"): Read a 64-bit integer with varint encoding. In R the value is stored as a double which looses some precision (no other way)
