MULTILINE

static final int MULTILINE

Affects the behaviour of "^" and "$" tags. When switched off:

the "^" matches the beginning of the whole text; the "$" matches the end of the whole text, or just before the '\n' or "\r\n" at the end of text. When switched on: the "^" additionally matches the line beginnings (that is just after the '\n'); the "$" additionally matches the line ends (that is just before "\r\n" or '\n'); Corresponds to "m" in Perl notation.

DOTALL

static final int DOTALL

Affects the behaviour of dot(".") tag. When switched off:

the dot matches any character but EOLs('\r','\n'); When switched on: the dot matches any character, including EOLs. This flag is sometimes referenced in regex tutorials as SINGLELINE, which confusingly seems opposite to MULTILINE, but in fact is orthogonal. Corresponds to "s" in Perl notation.
