The BasicString class is used by the String class to convert null-terminated character arrays and String objects to a common representation. It is a light-weight class that contains just a pointer to a character array and an integer specifying the length of that array. The instantiation of a BasicString object is therefore a cheap operation.
This class is normally instantiated implicitly by the compiler using one of the conversion constructors.
| jem::BasicString::BasicString | ( | const char * | str | ) |
Creates a BasicString from a null-terminated character array
| str | - a null-terminated character array or NULL. |
| jem::BasicString::BasicString | ( | const char * | str, |
| int | n | ||
| ) |
Creates a BasicString from the first n elements in the character array str.
| str | - a null-terminated character array of length n. If n is zero, str may be NULL. |
| n | - the length of the character array str. |
n >= 0this->size() == n | jem::BasicString::BasicString | ( | const String & | str | ) |
Creates a BasicString from the String str.
| str | - a String object. |
this->size() == str.size() | char jem::BasicString::operator[] | ( | int | i | ) | const |
Returns the i-th character of this BasicString.
| i | - the character index. |
BasicString.i >= 0 && i < this->size() | int jem::BasicString::size | ( | ) | const |
BasicString.
