示例1: h5WriteInt
//'@title This function writes an integer meta data to file
//'
//'@description This function is inteded for internal use
//'
//'@param intName the name of the meta data item to be written
//'@param integer int that will be written to the meta data described by intName
//'@param filePath character path to the h5 file where data will be written
//'@param update int flag for whether item is new (0) or whether it will overwrite a previous item (1)
//'@return int 0
// [[Rcpp::export]]

// Group Meta Group

}示例2: h5WriteCharVector
//'@title This function writes a character vector to the meta data
//'
//'@description This function writes a character vector to the meta data and is intended for internal use.
//'
//'@param charName the name that will be given to the meta data character vector
//'@param charVec the character vector to be written as meta data
//'@param filePath the path to the h5 file where the data will be written
//'@param update integer denoting whether the data item is new or whether it is an update
//'(which will overwrite any previous item)
//'@return int 0
// [[Rcpp::export]]
