Class NpgsqlLengthCache

Namespace

Npgsql

Assembly

Npgsql.dll

An array of cached lengths for the parameters sending process.

When sending parameters, lengths need to be calculated more than once (once for Bind, once for an array, once for the string within that array). This cache optimized that. Lengths are added to the cache, and then retrieved at the same order.
