Examples of ExpressionOperator

com.draagon.meta.manager.exp.ExpressionOperator
oracle.toplink.essentials.expressions.ExpressionOperator

Purpose: ADVANCED: The expression operator is used internally to define SQL operations and functions. It is possible for an advanced user to define their own operators.
org.apache.pig.backend.hadoop.executionengine.physicalLayer.expressionOperators.ExpressionOperator
A base class for all types of expressions. All expression operators must extend this class.
org.apache.pig.impl.logicalLayer.ExpressionOperator
org.eclipse.persistence.expressions.ExpressionOperator

Purpose: ADVANCED: The expression operator is used internally to define SQL operations and functions. It is possible for an advanced user to define their own operators.
