Package org.apache.ofbiz.entity.condition

Class EntityConditionBase

java.lang.Object

org.apache.ofbiz.entity.condition.EntityConditionBase

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

EntityCondition, EntityConditionValue, EntityOperator

public abstract class EntityConditionBase
extends Object
implements Serializable

Represents the conditions to be used to constrain a query.

An EntityCondition can represent various type of constraints, including:

• EntityConditionList: a list of EntityConditions, combined with the operator specified
• EntityExpr: for simple expressions or expressions that combine EntityConditions
• EntityFieldMap: a map of fields where the field (key) equals the value, combined with the operator specified

These can be used in various combinations using the EntityConditionList and EntityExpr objects.
