getDataStructures | R Documentation |
This function retrieves descriptions of the data structures defined in a source file or translation unit. This includes unions, structs and typedefs.
getDataStructures(src, fileFilter = character(), collector = genDataStructCollector(), ...)
getStructDef(type, kids = children(tp), class = "StructDefinition")
getTypedefs(src, fileFilter = character(), col = genTypedefCollector(), ...)
src |
the already created CXTranslationUnit object, or the name of the source file |
collector , col |
a visitor function or visitor object of class
|
fileFilter |
a character vector. This is used to identify the files/directories of interest and to identify the cursors we want in the results. This can be a single string that is a regular expression. Alternatively, it can be a vector of directory or file names. For a vector of values, we check which correspond to actual file or directory names. For these, we filter the cursors based on whether they are in the specified file names, within files in the specified directories. For elements that are not files or directories, we use these as regular expressions. This mechanism allows us to include cursors by explicit file name, explicit directory, or by regular expression. |
