Method Detail

getActiveFlags

protected int getActiveFlags()

flagActive

protected boolean flagActive(int flag)

getJavaCharacterForFlag

@CheckForNull
protected JavaCharacter getJavaCharacterForFlag(int flag)

Returns the character inside the regex that was used to set the given flag. This will return null if the flag is not set or if the flag has been set from outside of the regex (i.e. as an argument to Pattern.compile). Therefore this should not be used to check whether a flag is set.
