Description

TMemoryStream is a stream that stores its data in dynamic memory.

FireDAC.Comp.DataSet.TFDBlobStream inherits from System.Classes.TMemoryStream. All content below this line refers to System.Classes.TMemoryStream.

TMemoryStream is a stream that stores its data in dynamic memory.

Use TMemoryStream to store data in a dynamic memory buffer that is enhanced with file-like access capabilities. TMemoryStream provides the general I/O capabilities of a stream object while introducing methods and properties to manage a dynamic memory buffer.

Memory streams are useful as intermediary objects that can hold information as well as read it from or write it to another storage medium. They provide a useful format for comparing the contents of streams, or for manipulating data that is stored in a less accessible medium.
