public ProtoConverter()

ProtoConverter

public ProtoConverter(boolean validateColPosition)

Instantiate a {ProtoConverter} using a typeMap.

Parameters:

validateColPosition - whether to consider column position in this converter. By default, a {TiDAGRequest} should check whether a {ColumnRef}'s position is correct in it's executors. Can ignore this validation if `validateColPosition` is set to false.
