Method Detail

valueType

public ValueType valueType()

Description copied from interface: ScalarReader

Describe the type of the value. This is a compression of the value vector type: it describes which method will return the vector value.

Returns:

the value type which indicates which get method is valid for the column

extendedType

public ValueType extendedType()

Description copied from interface: ScalarReader

The extended type of the value, describes the secondary type for DATE, TIME and TIMESTAMP for which the value type is int or long.

Specified by:
