object as function

[babu198649]

hi,i came across a program where one line goes like this

SQ_Config::inst ance()->readBoolEntry( "mount_devi ce", false)

here i found that SQ_Config is a class but there is no function called
instance().i had ran the program and it works fine.
please clarify thanks in advance.

Are you sure that there is no method called instance?

This is singleton class,which means that inside the class there must be a static pointer to the class,in this case instance().Is this class derived?

You can also use a debugger to follow the code. Stop it at that line and step through the program to see where the program ends up.
