lets say that it is only the `coupon` field that we are interested in, then its better not to have to
deserialize the whole object that implements the `BondVOInterface`. Chronicle will look a the types of keys
and values that you set up in the builder, If the value type is a simple accessor/mutator interfaces
inother words a simple interface that is exposing non nested pojo with coresonding getX() and setX()
methods Chronicle is able to be act in a more efficient way, by just deserialize the field(s) that we
require, in this
example just the coupon. This is why we created
the`ChronicleMapBuilder`, when you use this builder chronicle will not create on heap copies of your whole data structure. You can instead use proxy objects that can read and write into the off heap data structures, this reduced serialisation can give you a big performance boost. Below we show you how you can work directly with the off heap entries.
deserialise the whole object that implements the `BondVOInterface`. The `ChronicleMapBuilder` will look a the types of keys
and values that you use, If the value type is a simple accessor/mutator interface that is exposing a non nested pojo, which uses simple types
like String and primitives with corresponding get..() and
set..() methods, Chronicle is able to generate off heap poxies so the whole object is not desrialized each
time it is accessed,
So when you specify a simple Pojo interface you access the off heap memory via an internal proxy
object, it is able to read
and write into
the off heap
data
structures directly, this reduced serialisation can give you a big performance boost. Below we show you how

``` java
ChronicleMap<String, BondVOInterface> chm = ChronicleMapBuilder
.of(String.class, BondVOInterface.class)
.keySize(10)
.create();
