Return true if \textit{key} exists in \texttt{ESMF\_Info}'s storage. ! ! The arguments are: ! \begin{description} ! \item [info] ! Target \texttt{ESMF\_Info} object. ! \item [key] ! String key to access in \texttt{ESMF\_Info} storage. See section \ref{info_key_format} ! for an overview of the key format. ! \item [{[attnestflag]}] ! Setting to \texttt{ESMF\_ATTNEST\_ON} triggers a recursive search for ! \textit{keyParent}. The first instance of the key will be found in the ! hierarchy. Default is \texttt{ESMF\_ATTNEST\_OFF}. ! \item [{[isPointer]}] ! Default is true. If true, expect the \textit{key} is using JSON Pointer ! syntax (see section \ref{info_key_format}). Setting to false will trigger ! a slightly faster search. ! \item [{[rc]}] !
