MemoryStreamSample

This application is a sample which accessing memory stream.

MemoryInputStream

Functions

• integerByteOrder ... .littleEndian or .bigEndian
• streamDataLength ... The length of readable bytes from stream.
• open() and close()
• readInteger() -> T ... T is UInt8, UInt16, UInt32 and UInt64.
• readString(length: Int) -> String
• readData(length: Int) -> Data
• readBytes(length: Int) -> [UInt8]

Example

let data = Data(bytes: [0x01, 0x02, 0x03, 0x04])
let stream = MemoryInputStream(data: data)
stream.integerByteOrder = .bigEndian
stream.open()
do {
	let a: UInt16 = try stream.readInteger()
	let b: UInt16 = try stream.readInteger()
	print("a=\(a), b=\(b)")
} catch {
	print("\(error)")
}
stream.close()

MemoryOutputStream

Functions

• integerByteOrder ... .littleEndian or .bigEndian
• open() and close()
• write(integer: T) ... T is UInt8, UInt16, UInt32 and UInt64.
• write(string: String, length: Int)
• write(data: Data, length: Int)
• write(bytes: [UInt8], length: Int)
• data() -> Data ... Get data are pooled in the stream.

Example

let stream = MemoryOutputStream()
stream.integerByteOrder = .bigEndian
stream.open()
do {
	let a = UInt16(0x0102)
	let b = UInt16(0x0304)
	try stream.write(integer: a)
	try stream.write(integer: b)
} catch {
	print("\(error)")
}
stream.close()
let data = stream.data()
print("data=\(data)")

Requirements

• macOS 10.12
