10.4. Types

The Type interface in Presto is used to implement a type in the SQL language. Presto ships with a number of built-in types, like VarcharType and BigintType. The ParametricType interface is used to provide type parameters for types, to allow types like VARCHAR(10) or DECIMAL(22, 5). A Plugin can provide new Type objects by returning them from getTypes() and new ParametricType objects by returning them from getParametricTypes().

Below is a high level overview of the Type interface, for more details see the JavaDocs for Type.
