Class StatementBuilder

java.lang.Object

com.google.api.ads.dfp.axis.utils.v201203.StatementBuilder

All Implemented Interfaces:

QueryBuilderInterface<Value>

public final class StatementBuilder
extends Object
implements QueryBuilderInterface<Value>

StatementBuilder allows for statements to be constructed in parts.

Typical usage is:

 StatementBuilder statementBuilder = new StatementBuilder()
     .where("lastModifiedDateTime > :yesterday AND type = :type")
     .orderBy("name DESC")
     .limit(200)
     .offset(20)
     .withBindVariableValue("yesterday",
         DateTimes.fromDate(new org.joda.time.DateTime().minusDays(1).toDate()))
     .withBindVariableValue("type", "Type")

 Statement statement = statementBuilder.toStatement();
 //...
 statementBuilder.increaseOffsetBy(20);
 statement = statementBuilder.toStatement();
