Provide a
find-usages for variable assignments that iterates over assignments and method
parameter bindings.
For
example:
void
boo()
{
int a =
Integer.parseInt(System.getProperty("foo"));
bar(a,
false);
}
void
foo()
{
bar(3,
true);
}
void bar(int a,
boolean q)
{
int
b;
if
(q)
b
= a;
else
b
= 7;
System.out.println(b);
}
In this case, doing
a "transitive" find usage (for assignments) should result in the following
list:
boo(): a =
Integer.parseInt(System.getProperty("foo"));
foo(): bar(3,
true);
bar(): a [ input
parameter ]
bar(): b =
7
In other words, if a
find usage is performed on a variable A, the find usage should include usages on
any variable B in the code, where B is in the transitive closure of { variables
that are assigned directly to A; variables that are implicitly assigned
to A through a parameter in a method call }
This should be an
option in the find usages dialog. Presumably not on by
default.
