  5. 8.x-4.x advagg_js_minify/jshrink.inc \JShrink\Minifier::processMultiLineComments()

Skips multiline comments where appropriate, and includes them where needed. Conditional comments and "license" style blocks are preserved.

Parameters

int $startIndex The index point where "getReal" function started:

Return value

bool|string False if there's no character

Throws

\RuntimeException Unclosed comments will throw an error

1 call to Minifier::processMultiLineComments()
Minifier::getReal in advagg_js_minify/jshrink.inc
This function gets the next "real" character. It is essentially a wrapper around the getChar function that skips comments. This has significant performance benefits as the skipping is done using native functions (ie, c code) rather than in script php.
