Re: Union followed by Property does not compile !

The presented solution is inconsistent in two ways:

1. Property of union not possible.

2. Order of field and property violations "field before property" rule.

Today I remember the rule which this union field is conflicting with.

The rule: "field before property"

Going to demonstrate it below

There are apperently two problems with this solution:

1. Property of union not possible ?!?

2. Inconsistent language design in respect to standard field + property relation
(order of appearance/declaration)

// ERROR "field definition not allowed after methods or properties" problem 2.

}


type
	TDataExample3 = record

//		mStandardField : integer;  // OK

		// normal/standard property
		property StandardField : integer read mStandardField write mStandardField;

		mStandardField : integer;  // ERROR "field definition not allowed after methods or properties" problem 2.


		// union property
//		property UnionField : int64 read mData write mData;  // not possible, problem 1

		// union fields
		case integer of   // INCONSISTENT problem 2
			0 : ( mData : int64 );
			1 : ( mByte : packed array[0..7] of byte );

//		property UnionField : int64 read mData write mData;  // not possible, problem 1

	end;
