Get vector version counter — vector_version

Returns the version counter for a vector property, which is incremented when the vector is modified. This is useful for cache invalidation.

Usage

vector_version_counter(daf, axis, name)

Arguments

daf: A Daf object
axis: Name of the axis
name: Name of the vector property

Value

A character string representing the current counter value. Returned as a string rather than an R integer because the Julia-side counter is a UInt32 that can exceed R's signed-integer range.

Details

The version counter is incremented whenever the vector data is modified. Compare counters with identical() or == on the strings.
