## Detailed Description

Container for metadata describing how to unserialize grids from and/or serialize grids to a stream (which file format, compression scheme, etc. to use)

This class is mainly for internal use.

## Member Typedef Documentation

## AuxDataMap

using AuxDataMap = std::map<std::string, std::any>

## ConstPtr

using ConstPtr = SharedPtr<const StreamMetadata>

## Ptr

using Ptr = SharedPtr<StreamMetadata>

## Member Function Documentation

## auxData() [1/2]

AuxDataMap & auxData | ( |  | ) |

Return a map that can be populated with arbitrary user data.

## auxData() [2/2]

const AuxDataMap & auxData | ( |  | ) | const

## backgroundPtr()

const void * backgroundPtr | ( |  | ) | const

## compression()

uint32_t compression | ( |  | ) | const

## countingPasses()

bool countingPasses | ( |  | ) | const

## delayedLoadMeta()

bool delayedLoadMeta | ( |  | ) | const

## fileVersion()

uint32_t fileVersion | ( |  | ) | const

## gridClass()

uint32_t gridClass | ( |  | ) | const

## gridMetadata() [1/2]

MetaMap & gridMetadata | ( |  | ) |

Return a (reference to a) copy of the metadata of the grid currently being read or written.

Some grid metadata might duplicate information returned by gridClass(), backgroundPtr() and other accessors, but those values are not guaranteed to be kept in sync.
