Package org.apache.calcite.sql.fun

Class SqlBasicOperator

java.lang.Object

org.apache.calcite.sql.SqlOperator

org.apache.calcite.sql.fun.SqlBasicOperator

public final class SqlBasicOperator
extends SqlOperator

Concrete implementation of SqlOperator.

The class is final, and instances are immutable.

Instances are created only by create(java.lang.String) and are "modified" by "wither" methods such as withPrecedence(int, boolean) to create a new instance with one property changed. Since the class is final, you can modify behavior only by providing strategy objects, not by overriding methods in a subclass.
