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.
CopyFrompublicCopies a specified number of bytes from one stream to another.
CreatepublicCreates an instance of TBlobStream.
DefaultHandlerpublicProvides the interface for a method that processes message records.
DestroypublicDestroys an instance of TBlobStream.
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.
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 current position in the field's data into Buffer.
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.
SafeCallExceptionpublicHandles exceptions in methods declared using the safecall calling convention.
SeekpublicResets the current position of the TBlobStream object.
SetSizeprotectedProvides a placeholder for a method to change the size of the streamed resource.
ToStringpublicReturns a string containing the class name.
TruncatepublicDiscards all data in the BLOB field from the current position on.
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 field 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.
