Subject:         Refactor value <-> CFNumber conversions into some helper functions
X-Git-Url: https://git.webkit.org/?p=WebKit-https.git;a=commitdiff_plain;h=948bb3ea894444bc35802a72cb0dd30ff50aa791;ds=inline

    Refactor value <-> CFNumber conversions into some helper functions

        Reviewed by Jon.

        * WebPreferences.cpp:
        (preferencesPath): Changed to return a const String&.
        (numberValueForPreferencesValue): Converts a value from preferences to
        a native numeric type.
        (cfNumber): Converts a native numeric value to a CFNumberRef.
        (booleanValueForPreferencesValue): Converts a value from preferences
        to a native boolean.
        (WebPreferences::integerValueForKey): Changed to call
        numberValueForPreferencesValue.
        (WebPreferences::floatValueForKey): Ditto.
        (WebPreferences::boolValueForKey): Changed to call
        booleanValueForPreferencesValue.
        (WebPreferences::setIntegerValue): Changed to call cfNumber.
        (WebPreferences::setLongLongValue): Ditto.
