glvalueとは 意味・読み方・使い方

名詞

glvalue (plural glvalues)

1. (programming) A value that is either an xvalue or an lvalue.
   • 2010 March 12, William M. Miller, “A Taxonomy of Expression Value Categories”, in C++ Standards Committee Papers‎, pages 3, 16:

     Together, xvalues and lvalues are called “glvalues” (“generalized” lvalues). […] If the second and third operands are glvalues of the same value category and have the same type, the result is of that type and value category and it is a bit-field if the second or the third operand is a bit-field, or if both are bit-fields.

   • 2010 April, Bjarne Stroustrup, “"New" Value Terminology”, in stroustrup.com‎, page 4:

     So, the left leg of the W is “lvalue” and “glvalue” and the right leg is “prvalue” and “rvalue.” Incidentally, every value is either a glvalue or a prvalue, but not both.
