java.lang.Object

com.mysema.query.BooleanBuilder

All Implemented Interfaces:

Expression<java.lang.Boolean>, Predicate, java.io.Serializable, java.lang.Cloneable

public final class BooleanBuilder
extends java.lang.Object
implements Predicate, java.lang.Cloneable

BooleanBuilder is a cascading builder for Predicate expressions. BooleanBuilder is a mutable Expression implementation.

Usage example:

 QEmployee employee = QEmployee.employee;
 BooleanBuilder builder = new BooleanBuilder();
 for (String name : names) {
     builder.or(employee.name.equalsIgnoreCase(name));      
 }
