--------------------------------------
Summary: Unify the data structures of arithmetic expressions and
logical expressions
Key: IOTDB-1413
URL: https://issues.apache.org/jira/browse/IOTDB-1413
Project: Apache IoTDB
Issue Type: Sub-task
Reporter: Steve Yurong Su
Currently, arithmetic expressions and logical expressions do not share the same
root expression class.
Arithmetic expression classes are inherited from
org.apache.iotdb.db.query.expression.Expression.
Logical expressions classes are inherited from
org.apache.iotdb.tsfile.read.expression.IExpression.
If we want to support arithmetic expressions in WHERE clauses, they must have
the same class inheritance.
