getBaseType

public Schema.FieldType getBaseType()

Description copied from interface: Schema.LogicalType

The base Schema.FieldType used to store values of this type.

Specified by:

getBaseType in interface Schema.LogicalType<T,T>

toBaseType

public T toBaseType(T input)

Description copied from interface: Schema.LogicalType

Convert the input type to the type Java type used by the base Schema.FieldType.

Specified by:
