Detailed Description

Set threshold for attribute storage.

HDF5 can store Attributes in the object header (compact) or in the B-tree (dense). This property sets the threshold when attributes are moved to one or the other storage format.

Please refer to the upstream documentation of H5Pset_attr_phase_change or Section 8 (Attributes) in the User Guide, in particular Subsection 8.5.

AttributePhaseChange() [1/2]

HighFive::AttributePhaseChange::AttributePhaseChange ( unsigned max_compact, unsigned min_dense )

inline

Create the property from the threshold values.

When the number of attributes hits max_compact the attributes are moved to dense storage, once the number drops to below min_dense the attributes are moved to compact storage.

AttributePhaseChange() [2/2]

HighFive::AttributePhaseChange::AttributePhaseChange ( const GroupCreateProps & gcpl )

inlineexplicit

Extract threshold values from property list.
