LValue

boolean LValue

An expression with left value set to true can be put on the left sign of an assignation; otherwise, they can't. An example of expression with LValue is a variable:

 a = 3; 

An expression without LValue could be a literal or an addition:

 "Hello"="world"; // Incorrect; "Hello" does not have LValue
 a+b = c;         // Incorrect: a+b has no LValue
 

Keep in mind that these are examples. Of course your languajes could consider having literals with lvalues...

RValue

boolean RValue

An expression with no Rvalue cannot be used on the right side of an assignation, because they are not "readable". The typical example is an invocation to a method that returns nothing:

 void voidFunction() {...}
 
 ...
 
 int a = voidFunction(); // Incorrect; Rvalue required
 

Of course this is an example. Some languajes might find useful setting LValue to true in this kind of function calls (thus recuperating a void value).

EValue

java.lang.Object EValue

This is a calculated value. Some initializations must be calculated in compile-time; for example static attribute initialization:

 class MyDumbClass{
   public int staticInt = 1+5+6;
 }
 

The value for literal "1" will be the integer 1, the value for literal "5" will be the integer 5, and the value for "6" will the the integer 6. This way, "1+5+6" can be evaluated in compile time (and set to 12).

Other use for this field is in iterpreters: The only way of calculating values is having them dynamically stored in the ASTs.
