Boolean method is always inverted
Reports methods with a boolean
return type that are always negated when called.
A quick-fix is provided to invert and optionally rename the method. For performance reasons, not all problematic methods may be highlighted in the editor.
Example:
class C {
boolean alwaysTrue() {
return true;
}
void f() {
if (!alwaysTrue()) {
return;
}
}
boolean member = !alwaysTrue();
}
After the quick-fix is applied:
class C {
boolean alwaysFalse() {
return false;
}
void f() {
if (alwaysFalse()) {
return;
}
}
boolean member = alwaysFalse();
}
