Name Remarks Include Path Unreal Specifiers

static const TArray< TSharedPtr< FJsonValue > > & ReadArray ( TSharedPtr< class FJsonObject > Item,
const FString& Key
)

 Returns the array named Key or nullptr if it is missing or the wrong type. PaperJSONHelpers.h  

static bool ReadBoolean ( const TSharedPtr< class FJsonObject > Item,
const FString& Key,
bool bDefaultIfMissing
)

 Returns the bool named Key or bDefaultIfMissing if it is missing or the wrong type (note: no way to determine errors!) PaperJSONHelpers.h  

static bool ReadFloatNoDefault ( const TSharedPtr< class FJsonObject > Item,
const FString& Key,
float& Out_Value
)

 Returns true if the field named Key is a Number, populating Out_Value, or false if it is missing or the wrong type (Out_Value is set to 0.0f on failure) PaperJSONHelpers.h  

static bool ReadFloatNoDefault ( const TSharedPtr< class FJsonObject > Item,
const FString& Key,
double& Out_Value
)

 Returns true if the field named Key is a Number, populating Out_Value, or false if it is missing or the wrong type (Out_Value is set to 0.0f on failure) PaperJSONHelpers.h  

static bool ReadIntegerNoDefault ( const TSharedPtr< class FJsonObject > Item,
const FString& Key,
int32& Out_Value
)

 Returns true if the field named Key is a Number (truncating it to an integer), populating Out_Value, or false if it is missing or the wrong type (Out_Value is set to 0 on failure) PaperJSONHelpers.h  

static bool ReadIntPoint ( const TSharedPtr< class FJsonObject > Item,
const FString& Key,
FIntPoint& Out_XY
)

 Returns true if the object named Key is a struct containing two floats (x,y), populating XY with the values) PaperJSONHelpers.h  

static TSharedPtr< class FJsonObject > ReadObject ( TSharedPtr< class FJsonObject > Item,
const FString& Key
)

 Returns the object named Key or nullptr if it is missing or the wrong type. PaperJSONHelpers.h  

static bool ReadRectangle ( const TSharedPtr< class FJsonObject > Item,
const FString& Key,
FIntPoint& Out_XY,
FIntPoint& Out_WH
)

 Returns true if the object named Key is a struct containing four integers (x,y,w,h), populating XY and WH with the values) PaperJSONHelpers.h  

static bool ReadSize ( const TSharedPtr< class FJsonObject > Item,
const FString& Key,
FVector2D& Out_WH
)

 Returns true if the object named Key is a struct containing two floats (w,h), populating WH with the values) PaperJSONHelpers.h  

static FString ReadString ( TSharedPtr< class FJsonObject > Item,
const FString& Key,
const FString& DefaultValue
)

 Returns the value of Key in Item, or DefaultValue if the Key is missing or the wrong type PaperJSONHelpers.h  

static bool ReadXY ( const TSharedPtr< class FJsonObject > Item,
const FString& Key,
FVector2D& Out_WH
)

 Returns true if the object named Key is a struct containing two floats (x,y), populating WH with the values) PaperJSONHelpers.h
