com.datasalt.pangool.io.Schema
A field is an abstract data type that can be one of this:
- A 32-bit signed int;
- A 64-bit signed long;
- A 32-bit IEEE single-float; or
- A 64-bit IEEE double-float; or
- A unicode string;
- A boolean; or
- An enum, containing one of a small set of symbols;
- A byte buffer
- An arbitrary object, serializable by Hadoop's serialization
A field can be constructed using one of its static createXXX methods. A field object is immutable.
