Class TStream

type TStream = class

Base class for streams

Streams can read from and/or write to files (including text ones), memory, etc

	`function Read(out Buffer; const Count: Cardinal): Cardinal; virtual; abstract;`
	`function ReadCheck(out Buffer; const Count: Cardinal): Boolean;`
	`function Seek(const NewPos: Cardinal): Boolean; virtual;`
	`procedure SetSize(const Value: Cardinal); virtual;`
	`function Write(const Buffer; const Count: Cardinal): Cardinal; virtual; abstract;`
	`function WriteCheck(const Buffer; const Count: Cardinal): Boolean;`

Reads Count bytes from the stream to Buffer, moves current position forward for number of bytes read and returns this number

Reads Count bytes from the stream to Buffer, moves current position forward for number of bytes read and returns True if success

Changes the current position of the stream (if such changes are supported by particular stream class)

Changes current size of the stream

Writes Count bytes from Buffer to the stream, moves current position forward for the number of bytes written and returns this number

Writes Count bytes from Buffer to the stream, moves current position forward for the number of bytes written and returns True if success

	`property Position: Cardinal;`
	`property Size: Cardinal;`

Current position within the stream in bytes

Current size of the stream in bytes
