Assigns the contents.

  1. Copy assignment operator. Assigns the contents of other. Equivalent to assign(other);.

  2. Move assignment operator. Assigns the contents of other using move semantics. other is in valid, but unspecified state after the operation. Equivalent to assign(other);.

  3. Assigns a null-terminated character string pointed to by ptr. Equivalent to assign(ptr);.

  4. Assigns characters contained in initializer list il. Equivalent to assign(il);.

  5. Assigns the contents of the string p. Equivalent to assign(p);.

[edit] Parameters

other - another regex object
ptr - pointer to a null-terminated character string
il - initializer list containing characters to assign
p - string containing characters to assign

[edit] Return value

*this
