ArrayStream

An InputStream that encapsulates contents of an array

class ArrayStream : InputStream {

import std.algorithm;;

this();

this(ubyte[] data, size_t size);

this(ubyte[] data);

void close();

bool readable();

size_t readBytes(void* buffer, size_t count);

bool seekable();

StreamPos getPosition();

bool setPosition(StreamPos pos);

StreamSize size();

}

Constructors

this this(): Constructor. Initializes stream as empty
this this(ubyte[] data, size_t size): Constructor. Initializes stream with an array of bytes. size delimits maximum read size
this this(ubyte[] data): Constructor. Initializes stream with an array of bytes

close void close(): Undocumented in source. Be warned that the author may not have intended to support it.
getPosition StreamPos getPosition(): Undocumented in source. Be warned that the author may not have intended to support it.
readBytes size_t readBytes(void* buffer, size_t count): Undocumented in source. Be warned that the author may not have intended to support it.
readable bool readable(): Undocumented in source. Be warned that the author may not have intended to support it.
seekable bool seekable(): Undocumented in source. Be warned that the author may not have intended to support it.
setPosition bool setPosition(StreamPos pos): Undocumented in source. Be warned that the author may not have intended to support it.

From InputStream

readable bool readable(): Returns true if there are any data to read. false means end of the stream.
readBytes size_t readBytes(void* buffer, size_t count): Attempts to read count bytes from stream and stores them in memory pointing by buffer. Returns number of bytes actually read
fillArray bool fillArray(T[] array): Attempts to fill an array with raw data from stream. Returns true if the array was filled, false otherwise
readLE bool readLE(T* value): Reads little-endian integer, converts to native-endian and stores in value
readBE bool readBE(T* value): Reads big-endian integer, converts to native-endian and stores in value

Examples

ubyte[] arr = [23,13,42,71,0,1,1,2,3,5,8];

auto stream = new ArrayStream(arr);
assert(stream.size() == arr.length);

ubyte[4] buf;
assert(stream.readBytes(buf.ptr, buf.length) == buf.length);
assert(buf == [23,13,42,71]);
assert(stream.getPosition() == buf.length);

assert(stream.setPosition(6));
assert(stream.getPosition == 6);
assert(stream.readBytes(buf.ptr, buf.length) == buf.length);
assert(buf == [1,2,3,5]);

assert(stream.readBytes(buf.ptr, buf.length) == 1);
assert(buf[0] == 8);
assert(!stream.readable);

stream.setPosition(1);
assert(stream.readable);
stream.seek(4);
assert(stream.readBytes(buf.ptr, buf.length) == buf.length);
assert(buf == [1,1,2,3]);

assert(stream.setPosition(arr.length));
assert(!stream.setPosition(arr.length+1));

stream.close();
assert(!stream.readable);
