Detailed Description

A utility class to amortize overhead from GA_GBElement attribute handling methods.

The GA_ElementWrangler class provides a simplified interface for common attribute operations as elements are added or removed.

This class is not thread-safe, so each thread should have its own copy, and any attributes added after its instantiation will not be processed.

void GA_ElementWrangler::hardenAllPages	(	GA_Offset	start_offset = `GA_Offset(0)`,

	)

Harden data pages in destination attributes. Will harden all pages overlapping the specified offset range. Once this is done, multiple threads can write to an attribute in parallel at a finer granularity than pages. Note groups are not threadsafe even if hardened.
