Class EntityConditionBase

java.lang.Object
  org.ofbiz.entity.condition.EntityConditionBase

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

EntityCondition, EntityConditionValue, EntityOperator

public abstract class EntityConditionBase
extends java.lang.Object
implements java.io.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.
