register

public GemfireRepositoryQuery register(@Nullable
 QueryPostProcessor<Repository,String> queryPostProcessor)

Registers the given QueryPostProcessor to use for processing OQL queries generated from Repository query methods. Registration always links the given QueryPostProcessor to the end of the processing chain of previously registered QueryPostProcessors. In other words, the given QueryPostProcessor argument will process OQL queries only after all QueryPostProcessor registered before it.

Parameters:

queryPostProcessor - QueryPostProcessor to register.

Returns:

this GemfireRepositoryQuery.
