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)
