CodeSnip Old Code (SVN)

Added new TBaseComparator<T> abstract base class for all comparator objects that must be able to construct a TRules<T> record that uses the comparator to supply the required IComparator<T> and IEqualityComparator<T> instances.

Changed all other comparer classes in unit to derive either directly or indirectly from TBaseComparator<T>.

Added changes to revision 4119 to v5 change-log.

Removed string comparer classes that have been made redundant by TStringComparator and TTextComparator.

Replaced use of TStringEqualityComparer with TStringComparator.

Removed unwanted debug output statement.

Modified EValidation.Assign to permit parameters that are not EValidation instances.

This fixes a bug introduced in parsnip that caused assertion failure in EValidation when parsing malformed entities in REML markup.

Replaced use of TTextComparer and TTextEqualityComparer with TTextComparator.

Added new TStringComparator and TTextComparator classes.
Added missing override directives to some methods of TDelegatedComparator.

Added new IComparator<T> interface and TComparator<T> and TDelegatedComparator<T> implementations.

Changed ISnippetIDList.Add from a function to a procedure.
Also changed so that an attempt to add the same snippet ID twice is silently ignored: this ensures the list acts like a set.
