Method used to "pass" this block.

Any other method of any other object can call this method. This is called 'public' access.

The data-type returned is "booltype"; Returns true if this block should be output or not.

This method is contained in the object "@block".

The method takes the following arguments:

filedef : Pointer to tgl_structure_parser

Not sure.

obj : Pointer to @schemaobj

Not sure.

first : booltype

If true, then return true only if the first item is true.

last : booltype

If true, then return true only if the last item is true.

C++

The files "tgl_condition.hpp" are included.

Query all of the conditions to see if any don't pass.

	for (ph::xmlobj::xmlobj_typed_vector<tgl_condition>::iterator i=_conditions.begin();
			i != _conditions.end(); i++)
	{
		if (!i->pass(filedef, obj, first, last))
			return false;
	}
	
	return true;
