マクロ定義詳解

CALL_PROTECTED

#define CALL_PROTECTED	(		InClass,
			InObj,
			MemberName )

値:

((InClass##MemberName##Accessor*)&(*InObj))->MemberName##Accessor

GET_PRIVATE

#define GET_PRIVATE	(		InClass,
			InObj,
			MemberName )

値:

(*InObj).*GetPrivate(InClass##MemberName##Accessor())

A macro for tidying up accessing of private members, through the above code

引数

InClass	The class being accessed (not a string, just the class, i.e. FStackTracker)
InObj	Pointer to an instance of the specified class
MemberName	Name of the member being accessed (again, not a string)

戻り値

The value of the member

GET_PRIVATE_REF

#define GET_PRIVATE_REF	(		InClass,
			InObj,
			MemberName )

値:

GET_PRIVATE(InClass, InObj, MemberName)

Redundant version of the above, for emphasizing the ability to assign a writable reference which can modify the original value

IMPLEMENT_GET_PRIVATE_VAR

#define IMPLEMENT_GET_PRIVATE_VAR	(		InClass,
			VarName,
			VarType )

値:

    struct InClass##VarName##Accessor \
    { \
        using Member = VarType InClass::*; \
        \
        friend Member GetPrivate(InClass##VarName##Accessor); \
    }; \
    \
    template struct AccessPrivate<InClass##VarName##Accessor, &InClass::VarName>;

Defines a class and template specialization, for a variable, needed for use with the GET_PRIVATE hook below

引数

InClass	The class being accessed (not a string, just the class, i.e. FStackTracker)
VarName	Name of the variable being accessed (again, not a string)
VarType	The type of the variable being accessed

IMPLEMENT_GET_PROTECTED_FUNC

#define IMPLEMENT_GET_PROTECTED_FUNC	(		InClass,
			FuncName,
			FuncRet,
			FuncParms,
			FuncParmNames )

値:

    IMPLEMENT_GET_PROTECTED_FUNC_CONST(InClass, FuncName, FuncRet, FuncParms, FuncParmNames,)

IMPLEMENT_GET_PROTECTED_FUNC_CONST

#define IMPLEMENT_GET_PROTECTED_FUNC_CONST	(		InClass,
			FuncName,
			FuncRet,
			FuncParms,
			FuncParmNames,
			FuncModifier )

値:

    struct InClass##FuncName##Accessor : public InClass \
    { \
        FORCEINLINE FuncRet FuncName##Accessor(FuncParms) FuncModifier \
        {\
            return FuncName(FuncParmNames); \
        } \
    };

Defines a class used for hack-accessing protected functions, through the CALL_PROTECTED macro below

引数

InClass	The class being accessed (not a string, just the class, i.e. FStackTracker)
FuncName	Name of the function being accessed (again, not a string)
FuncRet	The return type of the function
FuncParms	The function parameters
FuncParmNames	The names of the function parameters, as passed from one function to another
FuncModifier	(Optional) Modifier placed after the function - usually 'const'

LOCTEXT_NAMESPACE

#define LOCTEXT_NAMESPACE   "AtomEditor"

引数

InWidget

The widget to be tested

戻り値

Whether or not the widget matches a search condition

SearchForWidget()

TSharedRef< SWidget > SearchForWidget ( TSharedRef< SWidget > InWidget, FOnTestWidget InTester )

static

Iteratively searches through a widget and all its child widgets, for a widget, that passes the test delegate conditions

引数

InWidget	The widget to search
InTester	The delegate (usually a lambda) to do condition testing with

戻り値

The returned widget (or SNullWidget, if none)

SearchForWidgets()

bool SearchForWidgets ( TArray< TSharedRef< SWidget > > & OutMatches, TSharedRef< SWidget > InWidget, FOnTestWidget InTester, bool bMultiMatch = true )

static

引数

OutMatches	The array of widgets that results are passed to
InWidget	The widget to search
InTester	The delegate (usually a lambda) to do condition testing with
bMultiMatch	(Internal) Whether or not multiple matches are searched for (or just one single widget, the first match)
