AddDescendantprotectedAdds a new member.
AddPairpublicAdds a new JSON pair to the current JSON object.
AfterConstructionpublicResponds after the last constructor has executed.
BeforeDestructionpublicResponds before the first destructor executes.
ClassInfopublicReturns a pointer to the run-time type information (RTTI) table for the object type.
ClassNamepublicReturns a string indicating the type of the object instance (as opposed to the type of the variable passed as an argument).
ClassNameIspublicDetermines whether an object is of a specific type.
ClassParentpublicReturns the type of the immediate ancestor of a class.
ClassTypepublicReturns the class reference for the object's class.
CleanupInstancepublicPerforms finalization on long strings, variants, and interface variables within a class.
ClonepublicDeclares the method that should create a deep clone of the current JSON value.
CreatepublicCreates an instance of the TJSONObject class.
DefaultHandlerpublicProvides the interface for a method that processes message records.
DestroypublicDestroys the TJSONObject instance.
DispatchpublicCalls message-handling methods for the object, based on the contents of the Message parameter.
DisposeOfpublicDisposeOf forces the execution of the destructor code in an object.
EqualspublicChecks whether the current instance and the Obj parameter are equal.
EstimatedByteSizepublicDeclares the method that should return the estimated byte size of the current JSON object.
FieldAddresspublicReturns the address of a published object field.
FindValuepublicFinds and returns a TJSONValue instance located at the specified APath JSON path. Otherwise, returns nil.
FreepublicDestroys an object and frees its associated memory, if necessary.
FreeInstancepublicDeallocates memory allocated by a previous call to the NewInstance method.
GetpublicReturns the JSON pair specified by Index or Name in the current JSON object.
GetCountprotectedReturns the number of key-value pairs of this JSON object..
GetDisposedprotectedGetter for the Disposed property.
GetEnumeratorpublicReturns an enumerator that you can use to iterate through the JSON pairs in the current TJSONObject object.
GetHashCodepublicReturns an integer containing the hash code.
GetInterfacepublicRetrieves a specified interface.
GetInterfaceEntrypublicReturns the entry for a specific interface implemented in a class.
GetInterfaceTablepublicReturns a pointer to a structure containing all of the interfaces implemented by a given class.
GetPairprotectedReturns the key-value pair that has the specified I index in the list of pairs of the current JSON object, or nil if the specified I index is out of bounds.
GetPairByNameprotectedReturns the key-value pair, from the current JSON object, that has a key part matching the specified PairName string, or nil if there is no key matching PairName.
GetValuepublicReturns the value part from a key-value pair specified by the Name key in this JSON object, or nil if there is no key that matches Name.
InheritsFrompublicDetermines the relationship of two object types.
InitInstancepublicInitializes a newly allocated object instance to all zeros and initializes the instance's virtual method table pointer.
InstanceSizepublicReturns the size in bytes of each instance of the object type.
IsNullprotectedReturns True if the current JSON object represents a JSON null value.
MethodAddresspublicReturns the address of a class method by name.
MethodNamepublicReturns the name of a class method by address.
NewInstancepublicAllocates memory for an instance of an object type and returns a pointer to that new instance.
ParsepublicParses the given Data byte array and adds the encountered JSON pairs to the pairs of this JSON object.
ParseJSONValuepublicParses a non-null byte array and returns the JSON value corresponding to the parsed data, or null if the parsing fails.
ParseJSONValueUTF8 (deprecated)publicParses a byte array and returns the corresponding JSON value from it.
QualifiedClassNamepublicReturns the qualified name of the class.
RemovePairpublicRemoves a key-value pair having the specified PairName key part from the current JSON object.
SafeCallExceptionpublicHandles exceptions in methods declared using the safecall calling convention.
SetPairspublicDefines the list of key-value pairs that this JSON object contains.
Size (deprecated)publicReturns the number of pairs stored in the JSON object.
ToBytespublicSerializes the current JSON object content into an array of bytes.
ToJSONpublicReturns the string representation of this JSON object.
TryGetValuepublicFinds a TJSONValue object located at the specified APath JSON path, casts this JSON value as the T JSON type and fills AValue with the obtained JSON value. Returns True on success or False otherwise.
UnitNamepublicReturns the name of the unit where the class is defined.
UnitScopepublicReturns the class's unit scope.
ValuepublicValue methods should return the current JSON object as a string.
