 org.apache.parquet.schema.PrimitiveType primitiveType)

Accept a Parquet column.

This represents the constituents parts of a ColumnDescriptor in an easier to consume fashion. In particular, it is useful when the consumer wants to iterate the Typed-path from MessageType root to leaf without needing to resort to extraneous allocation of MessageType.getType(String...) or state management needed via GroupType.getType(String). The arguments of this method can be made into a ColumnDescriptor using ParquetSchemaUtil.makeColumnDescriptor(Collection, PrimitiveType).

Parameters:

typePath - the fully typed path

primitiveType - the leaf primitiveType, guaranteed to be the last element of path
