int BaseString::split ( Vector< BaseString > &  vector,

) const

Split a string into a vector of strings. Separate the string where any character included in separator exists. Maximally maxSize entries are added to the vector, if more separators exist in the string, the remainder of the string will be appended to the last entry in the vector. The vector will not be cleared, so any existing strings in the vector will remain.

Parameters:
separator characters separating the entries
vector where the separated strings will be stored
maximum number of strings extracted
Returns:
the number of string added to the vector
