Detailed Description

template<typename ValueType>
class juce::ScopedValueSetter< ValueType >

Helper class providing an RAII-based mechanism for temporarily setting and then re-setting a value.

E.g.

int x = 1;
 
{
    ScopedValueSetter setter (x, 2);
 
    // x is now 2
}
 
// x is now 1 again
 
{
    ScopedValueSetter setter (x, 3, 4);
 
    // x is now 3
}
 
// x is now 4
