◆ isValidAfterIdentifierInDeclarator()

static bool isValidAfterIdentifierInDeclarator ( const Token &  T)
static

isValidAfterIdentifierInDeclaratorAfterDeclSpec - Return true if the specified token is valid after the identifier in a declarator which immediately follows the declspec.

For example, these things are valid: 

 int x   [             4];         // direct-declarator
 int x   (             int y);     // direct-declarator

int(int x ) // direct-declarator int x ; // simple-declaration int x = 17; // init-declarator-list int x , y; // init-declarator-list int x asm ("foo"); // init-declarator-list int x : 4; // struct-declarator int x { 5}; // C++'0x unified initializers

This is not, because 'x' does not immediately follow the declspec (though ')' happens to be valid anyway). int (x)

static

Normalizes an attribute name by dropping prefixed and suffixed __.
