Detailed Description

common comparer for ZFFramework

Macro Definition Documentation

ZFComparerDefault

#define ZFComparerDefault

default comparer for common types, see ZFComparer

by default, compare by operator ==, you may use ZFCOMPARER_DEFAULT_DECLARE to supply your own type's compare method

ZFCOMPARER_DEFAULT_DECLARE

#define ZFCOMPARER_DEFAULT_DECLARE	(		T_Comparable0,
			T_Comparable1,
			compareAction )

declare a template specialization for ZFComparerDefault

usage:

ZFCOMPARER_DEFAULT_DECLARE(Type0, Type1, {
        return yourCompareMethod(v0, v1);
    })

Note

all subclass of the declared type would be specialized by this method, if you don't want it, use ZFCOMPARER_DEFAULT_DECLARE_EXPLICIT instead

ZFCOMPARER_DEFAULT_DECLARE_ALIAS

#define ZFCOMPARER_DEFAULT_DECLARE_ALIAS	(		T_Comparable0,
			T_Comparable1,
			compareAction )

util macro to alias compare action see ZFCOMPARER_DEFAULT_DECLARE

usage:

ZFCOMPARER_DEFAULT_DECLARE_ALIAS(T_Comparable0, T_Comparable1, OtherComparr)
