Julian Hyde created CALCITE-1929:
------------------------------------
Summary: Deprecate class RelDataTypeFactory.FieldInfoBuilder
Key: CALCITE-1929
URL: https://issues.apache.org/jira/browse/CALCITE-1929
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
Assignee: Julian Hyde
Since interface {{RelDataTypeFactory.FieldInfo}} is deprecated, and
{{RelDataTypeFactory.FieldInfoBuilder}} implements it, we should also deprecate
{{FieldInfoBuilder}}.
We will create a new class {{RelDataTypeFactory.Builder}} that does the same as
{{FieldInfoBuilder}} without implementing the {{FieldInfo}} interface.
For backwards compatibility, {{RelDataTypeFactory.builder()}} will continue to
return {{FieldInfoBuilder}} but we recommend that you assign the result to a
variable of type {{Builder}}. Thus you won't be using the deprecated class in
your code.
