Here is the caller graph for this function:

isArrayIndex() [1/3]

bool QJSNumberCoercion::isArrayIndex ( double d )

inlinestaticconstexpr

Checks whether d contains a value that can serve as an index into an array. For that, d must be a non-negative value representable as an unsigned 32bit int.

Here is the call graph for this function:

isArrayIndex() [2/3]

bool QJSNumberCoercion::isArrayIndex ( qint64 i )

inlinestaticconstexpr

Checks whether i contains a value that can serve as an index into an array. For that, d must be a non-negative value representable as an unsigned 32bit int.

isArrayIndex() [3/3]
