Factory method that creates the key type that matches the type of value.
For user defined derivations of CacheableKey, the method apache::geode::client::CacheableKey::create may be overloaded.

Implemented in apache::geode::client::CacheableDate, apache::geode::client::CacheableEnum, apache::geode::client::CacheableFileName, apache::geode::client::CacheableString, apache::geode::client::PdxSerializable, apache::geode::client::PdxWrapper, and apache::geode::client::PdxInstance.

return the size in bytes of the instance being serialized.
This is used to determine whether the cache is using up more physical memory than it has been configured to use. The method can return zero if the user does not require the ability to control cache memory utilization. Note that you must implement this only if you use the HeapLRU feature.
Reimplemented in apache::geode::client::CacheableDate, apache::geode::client::CacheableEnum, apache::geode::client::CacheableString, and apache::geode::client::PdxInstance.
