MemoryDevice

Simulates a device that you can write to and read from, behaves pretty much like a file

class MemoryDevice : IConduit {

size_t bufferSize();

const(void)[] peek();

istring toString();

bool isAlive();

void detach();

void error(istring msg);

size_t write(const(void)[] src);

OutputStream copy(InputStream src, size_t max);

OutputStream output();

size_t read(void[] dst);

void[] load(size_t max);

InputStream input();

long seek(long offset, Anchor anchor);

IConduit conduit();

IOStream flush();

void close();

}

Functions

bufferSize size_t bufferSize()
close void close(): Deletes the buffer and resets position
conduit IConduit conduit(): Used by FormatOutput and other streams.
copy OutputStream copy(InputStream src, size_t max): Copies src into this stream, overwriting any existing data
detach void detach(): Implemented because interfaces demand it, does nothing
error void error(istring msg): Throws an exception
flush IOStream flush(): Does nothing
input InputStream input()
isAlive bool isAlive(): Implemented because interfaces demand it, returns always true
load void[] load(size_t max)
output OutputStream output()
peek const(void)[] peek()
read size_t read(void[] dst): Reads into dst, starting to read from the current seek position
seek long seek(long offset, Anchor anchor): Change the internal seeker position
toString istring toString()
write size_t write(const(void)[] src): Write into this device, starting at the current seek position

From IConduit

bufferSize size_t bufferSize(): Return a preferred size for buffering conduit I/O.
toString istring toString(): Return the name of this conduit.
isAlive bool isAlive(): Is the conduit alive?
detach void detach(): Release external resources.
error void error(istring msg): Throw a generic IO exception with the provided msg.
Seek interface Seek: All streams now support seek(), so this is used to signal a seekable conduit instead.
Truncate interface Truncate: Indicates the conduit supports resize/truncation.
