Control whether pdx ignores fields that were unread during deserialization. The default is to
preserve unread fields be including their data during serialization. But if you configure the
cache to ignore unread fields then their data will be lost during serialization.
<P>
You should only set this attribute to <code>true</code> if you know this member will only be
reading cache data. In this use case you do not need to pay the cost of preserving the unread
fields since you will never be reserializing pdx data.

@param ignore <code>true</code> if fields not read during pdx deserialization should be
       ignored; <code>false</code>, the default, if they should be preserved.
