ParseArrayType()

std::tuple< std::string, std::vector< std::size_t > > ROOT::Internal::ParseArrayType

(

const std::string &

typeName

)

Parse a type name of the form T[n][m]... and return the base type T and a vector that contains, in order, the declared size for each dimension, e.g.

for unsigned char[1][2][3] it returns the tuple {"unsigned char", {1, 2, 3}}. Extra whitespace in typeName should be removed before calling this function.

If typeName is not an array type, it returns a tuple {T, {}}. On error, it returns a default-constructed tuple.
