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.
ClearpublicFrees the memory buffer, discarding all data associated with the memory stream.
CopyFrompublicCopies a specified number of bytes from one stream to another.
DefaultHandlerpublicProvides the interface for a method that processes message records.
DestroypublicDestroys an instance of TMemoryStream.
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.
FieldAddresspublicReturns the address of a published object field.
FixupResourceHeaderpublicPatches the resource header for a resource that has been written to the stream.
FreepublicDestroys an object and frees its associated memory, if necessary.
FreeInstancepublicDeallocates memory allocated by a previous call to the NewInstance method.
GetDisposedprotectedGetter for the Disposed property.
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.
GetSizeprotectedReturns the size of the streamed resource as an Int64.
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.
LoadFromFilepublicLoads the entire contents of a file into the memory buffer.
LoadFromStreampublicLoads the entire contents of a stream into the memory buffer.
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.
QualifiedClassNamepublicReturns the qualified name of the class.
ReadpublicReads up to Count bytes from the memory stream into Buffer and advances the current position of the stream by the number of bytes read.
ReadBufferpublicReads Count bytes from the stream into Buffer.
ReadBufferDatapublicMethods responsible for reading fixed Count or SizeOf(Buffer) number of bytes from the stream into Buffer.
ReadComponentpublicInitiates streaming of components and their properties.
ReadComponentRespublicReads components and their properties from a stream in a resource file format.
ReadDatapublicMethods responsible for reading up to Count but not more than SizeOf(Buffer) bytes from the stream into Buffer.
ReadResHeaderpublicReads a resource-file header from the stream.
ReallocprotectedSets the size of the internal buffer to the given capacity.
SafeCallExceptionpublicHandles exceptions in methods declared using the safecall calling convention.
SaveToFilepublicWrites the entire contents of the memory stream to the file with a given file name.
SaveToStreampublicWrites the entire contents of the memory stream to the stream object specified by Stream.
SeekpublicMoves the current position of the stream by Offset bytes, relative to the origin specified by Origin.
SetPointerprotectedReplaces the memory buffer associated with the memory stream.
SetSizepublicSets the Size property of the memory stream.
ToStringpublicReturns a string containing the class name.
UnitNamepublicReturns the name of the unit where the class is defined.
UnitScopepublicReturns the class's unit scope.
WritepublicWrites Count bytes from Buffer to the current position in the memory buffer and updates the current position by Count bytes.
WriteBufferpublicWrites Count bytes from Buffer onto the stream.
WriteBufferDatapublicWrites up to 4 four or Count bytes from Buffer onto the stream.
WriteComponentpublicInitiates the writing of components and their properties to a stream.
WriteComponentRespublicWrites components and their properties to a stream from a resource file format.
WriteDatapublicMethods responsible for writing up to Count bytes from Buffer to the stream.
WriteDescendentpublicStreams components and their properties in inherited forms.
WriteDescendentRespublicStreams components and their properties in inherited forms.
WriteResourceHeaderpublicWrites a resource-file header to the stream.
