3.5. キーによるクエリー

インデックス化されたエンティティーの keyEntity の指定

import org.infinispan.api.annotations.indexing.Basic;
import org.infinispan.api.annotations.indexing.Indexed;
import org.infinispan.api.annotations.indexing.Text;
import org.infinispan.protostream.GeneratedSchema;
import org.infinispan.protostream.annotations.ProtoFactory;
import org.infinispan.protostream.annotations.ProtoField;
import org.infinispan.protostream.annotations.ProtoSchema;

@Indexed(keyEntity = "model.StructureKey")
public class Structure {

   private final String code;
   private final String description;
   private final Integer value;

   @ProtoFactory
   public Structure(String code, String description, Integer value) {
      this.code = code;
      this.description = description;
      this.value = value;
   }

   @ProtoField(1)
   @Basic
   public String getCode() {
      return code;
   }

   @ProtoField(2)
   @Text
   public String getDescription() {
      return description;
   }

   @ProtoField(3)
   @Basic
   public Integer getValue() {
      return value;
   }

   @ProtoSchema(includeClasses = { Structure.class, StructureKey.class }, schemaPackageName = "model")
   public interface StructureSchema extends GeneratedSchema {
      StructureSchema INSTANCE = new StructureSchemaImpl();
   }
}

キーエンティティーとそのインデックス化フィールドの定義

import org.infinispan.api.annotations.indexing.Basic;
import org.infinispan.api.annotations.indexing.Indexed;
import org.infinispan.api.annotations.indexing.Keyword;
import org.infinispan.protostream.annotations.ProtoFactory;
import org.infinispan.protostream.annotations.ProtoField;

@Indexed
public class StructureKey {

   private String zone;
   private Integer row;
   private Integer column;

   @ProtoFactory
   public StructureKey(String zone, Integer row, Integer column) {
      this.zone = zone;
      this.row = row;
      this.column = column;
   }

   @Keyword(projectable = true, sortable = true)
   @ProtoField(1)
   public String getZone() {
      return zone;
   }

   @Basic(projectable = true, sortable = true)
   @ProtoField(2)
   public Integer getRow() {
      return row;
   }

   @Basic(projectable = true, sortable = true)
   @ProtoField(3)
   public Integer getColumn() {
      return column;
   }
}
