## Detailed Description

Internal functions for compressed read/write of a NanoVDB GridHandle into a stream.

Warning
  These functions should never be called directly by client code

## Function Documentation

## ◆ read() [1/2]

template<typename BufferT >

static void read | ( | std::istream & | is,
|  | BufferT & | buffer,
|  | Codec | codec
| ) |  |
| static

## ◆ read() [2/2]

void read | ( | std::istream & | is,
|  | char * | data,
|  | fileSize_t | residual,
|  | Codec | codec
| ) |  |
| static

read compressed grid from stream

Parameters

  is | input stream to read from
  data | data buffer to write into
  residual | expected size of uncompressed data
  codec | mode of compression

## ◆ write()

template<typename BufferT >

static fileSize_t write | ( | std::ostream & | os,
|  | const GridHandle< BufferT > & | handle,
|  | Codec | codec,
|  | uint32_t | n
| ) |  |
| static
