Array

Array manipulation typically involves appending, as in the following example:

// create a small buffer
auto buf = new Array (256);

auto foo = "to write some D";

// append some text directly to it
buf.append ("now is the time for all good men ").append(foo);

Alternatively, one might use a formatter to append content:

auto output = new TextOutput (new Array(256));
output.format ("now is the time for {} good men {}", 3, foo);

A slice() method returns all valid content within the array.

Constructors

this this(size_t capacity, size_t growing): Construct a buffer.
this this(void[] data): Construct a buffer.
this this(void[] data, size_t readable): Construct a buffer.

Functions

append Array append(const(void)[] src): Append content.
assign Array assign(void[] data): Reset the buffer content.
assign Array assign(void[] data, size_t readable): Reset the buffer content
assign void[] assign(): Access buffer content.
bufferSize size_t bufferSize(): Return a preferred size for buffering conduit I/O.
capacity size_t capacity(): Access buffer capacity.
clear Array clear(): Clear array content.
detach void detach(): Release external resources.
flush Array flush(): Emit/purge buffered content.
limit size_t limit(): Access buffer limit.
next bool next(size_t delegate(const(void)[]) scan): Iterator support.
opSlice void[] opSlice(size_t start, size_t end): Return a void[] read of the buffer from start to end, where end is exclusive.
position size_t position(): Access buffer read position.

~this ~this(): Clean up when collected. See method detach().
toString istring toString(): Return the name of this conduit.
bufferSize size_t bufferSize(): Return a preferred size for buffering conduit I/O.
read size_t read(void[] dst): Read from conduit into a target array. The provided dst will be populated with content from the conduit.
write size_t write(const(void)[] src): Write to conduit from a source array. The provided src content will be written to the conduit.
detach void detach(): Disconnect this conduit. Note that this may be invoked both explicitly by the user, and implicitly by the GC. Be sure to manage multiple detachment requests correctly: set a flag, or sentinel value as necessary.
timeout void timeout(uint millisec): Set the active timeout period for IO calls (in milliseconds.)
timeout uint timeout(): Get the active timeout period for IO calls (in milliseconds.)
isAlive bool isAlive(): Is the conduit alive? Default behaviour returns true.
conduit IConduit conduit(): Return the host. This is part of the Stream interface.
flush IOStream flush(): Emit buffered output or reset buffered input.
close void close(): Close this conduit.
error void error(istring msg): Throw an IOException, with the provided message.
error void error(int error_code, istring func_name, istring msg, istring file, long line): Throw an IOException, with the provided message, function name and error code.
input InputStream input(): Return the input stream.
output OutputStream output(): Return the output stream.
put Conduit put(void[] src): Emit fixed-length content from 'src' into this conduit, throwing an IOException upon Eof.
get Conduit get(void[] dst): Consume fixed-length content into 'dst' from this conduit, throwing an IOException upon Eof.
rewind Conduit rewind(): Rewind to beginning of file.
copy OutputStream copy(InputStream src, size_t max): Transfer the content of another conduit to this one. Returns the dst OutputStream, or throws IOException on failure.
seek long seek(long offset, Anchor anchor): Seek on this stream. Source conduits that don't support seeking will throw an IOException.
text char[] text(size_t max): Load text from a stream, and return them all in an array.
load void[] load(size_t max): Load the bits from a stream, and return them all in an array. The dst array can be provided as an option, which will be expanded as necessary to consume the input.
load void[] load(InputStream src, size_t max): Load the bits from a stream, and return them all in an array. The dst array can be provided as an option, which will be expanded as necessary to consume input.
put void put(void[] src, OutputStream output): Emit fixed-length content from 'src' into 'output', throwing an IOException upon Eof.
get void get(void[] dst, InputStream input): Consume fixed-length content into 'dst' from 'input', throwing an IOException upon Eof.
transfer size_t transfer(InputStream src, OutputStream dst, size_t max): Low-level data transfer, where max represents the maximum number of bytes to transfer.
