New refactoring - Simplify more complex boolean expressions

[JnRouvignac]

Example 1

This code:

if (b) {
    return someMethod();
} else {
    return false;
}

Can be rewritten to:

return b && someMethod();

Example 2

This code:

if (b) {
    return someMethod();
} else {
    return true;
}

Can be rewritten to:

return !b || someMethod();

Variations

• with local variable declaration
• with local variable assignment
• with instance variable assignment
• no else clause
• use of boolean primitives
• use of boolean objects
• ...
