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.

◆ gridMetadata() [2/2]

const MetaMap & gridMetadata ( ) const

◆ halfFloat()

bool halfFloat ( ) const

◆ leaf()

uint64_t leaf ( ) const

◆ libraryVersion()

VersionId libraryVersion ( ) const

◆ operator=()

StreamMetadata & operator= ( const StreamMetadata )

◆ pass()

uint32_t pass ( ) const

◆ seekable()

bool seekable ( ) const

◆ setBackgroundPtr()

void setBackgroundPtr ( const void *  )

◆ setCompression()

void setCompression ( uint32_t  )

◆ setCountingPasses()

void setCountingPasses ( bool  )

◆ setFileVersion()

void setFileVersion ( uint32_t  )

◆ setGridClass()

void setGridClass ( uint32_t  )

◆ setHalfFloat()

void setHalfFloat ( bool  )

◆ setLeaf()

◆ setWriteGridStats()

void setWriteGridStats ( bool  )

◆ str()

std::string str ( ) const

Return a string describing this stream metadata.

◆ transferTo()

void transferTo ( std::ios_base &  ) const

Transfer metadata items directly to the given stream.

◆ writeGridStats()

bool writeGridStats ( ) const
