sort_ constructors_ first
Constructor declarations should be before non-constructor declarations.
Description
#The analyzer produces this diagnostic when a constructor declaration is preceded by one or more non-constructor declarations.
Example
#
The following code produces this diagnostic because the constructor for
C
appears after the method
m
:
class C {
void m() {}
C();
}
Common fixes
#Move all of the constructor declarations before any other declarations:
class C {
C();
void m() {}
}
