FieldsInJavaAPIs

• A comma-separated list of field names
• The asterisk ("*") wildcard specifies all fields

(Use the REST API:field Resource to get a complete list of fields.)

• For fields in a Composite Object, use dot notation to specify the object's alias and the field name in that object.
  The pattern is: {aliasName}.{fieldName}. (When fetched, the alias becomes an array of records from the aliased object, where each item in the array contains the specified field.)
