Detailed Description

A set of delete-file pointers deduplicated by delete-file identity.

Delete files, especially deletion vectors, are identified by location plus content offset and content size. This mirrors Java's DeleteFileSet behavior.

Member Function Documentation

insert()

std::pair< iterator, bool > iceberg::DeleteFileSet::insert ( const value_type &  file )

inline

Insert a delete file into the set.

Parameters

file	The delete file to insert

Returns

A pair with an iterator to the inserted element (or the existing one) and a bool indicating whether insertion took place
