Syntax

class FCbObjectView : protected FCbFieldView

Remarks

Array of FCbField[View] that have unique names.

Accessing the fields of an object is always a safe operation, even if the requested field does not exist. Fields may be accessed by name or through iteration. When a field is requested that is not found in the object, the field that it returns has no value (evaluates to false) though attempting to access the empty field is also safe, as described by FCbFieldView.

This type only provides a view into memory and does not perform any memory management itself. Use FCbObject to hold a reference to the underlying memory when necessary.

Constructors

  Type Name Description
Public function   Construct an object with no fields.

Functions

  Type Name Description
Public function Const void

AppendHash ( FIoHashBuilder& Builder
)

 Append the hash of the object if serialized by itself with no name.
Public function Const FCbFieldView Access the object as an object field.
Public function Const FCbFieldViewIterator

begin ()

 DO NOT USE DIRECTLY. These functions enable range-based for loop support.
Public function Const void

CopyTo ( FArchive& Ar
)

 Copy the object into an archive.
Public function Const void Copy the object into a buffer of exactly GetSize() bytes, with no name.
Public function Const FCbFieldViewIterator  
Public function Const FCbIteratorSentinel

end ()

  
Public function Const bool

Equals ( const FCbObjectView& Other
)

 Whether this object is identical to the other object.
Public function  

FCbFieldView ( const FCbValue& Value
)

  
Public function constexpr  
Public function  

FCbFieldView ( const void* Data,
ECbFieldType Type
)

  
Public function Const FCbFieldView Find a field by case-sensitive name comparison.
Public function Const FCbFieldView Find a field by case-insensitive name comparison.
Public function Static FCbObjectView

FromFieldNoCheck ( const FCbFieldView& Field
)

 Construct an object from an object field. No type check is performed!
Public function Const FIoHash

GetHash ()

 Calculate the hash of the object if serialized by itself with no name.
Public function Const uint64

GetSize ()

 Returns the size of the object in bytes if serialized by itself with no name.
Public function Const void Invoke the visitor for every attachment in the object.
Public function Const bool

TryGetView ( FMemoryView& OutView
)

 Try to get a view of the object as it would be serialized, such as by CopyTo.
