Readers support both a C++ iostream type syntax, along with a get() syntax. Operations may be chained back-to-back.
All readers support the full set of native data types, plus a selection of array types. The latter can be configured to produce either a copy (.dup) of the buffer content, or a slice. See class SimpleAllocator, BufferAllocator and SliceAllocator for more on this topic.
The code below illustrates basic operation upon a memory buffer:
Buffer buf = new Buffer (256); // map same buffer into both reader and writer IReader r = new Reader(buf); IWriter w = new Writer(buf); int i = 10; long j = 20; double d = 3.14159; char[] c = "fred"; // write data types out w << c << i << j << d; // read them back again r >> c >> i >> j >> d; // reset buf.clear(); // same thing again, but using get() syntax instead w.put(c).put(i).put(j).put(d); r.get(c).get(i).get(j).get(d);
Readers may also be used with any class implementing the IReadable interface. See PickleReader for an example of how this can be put to good use.

Return the allocator associated with this reader.See ArrayAllocator for more information. Reimplemented from IReader. Definition at line 202 of file AbstractReader.d. References AbstractReader::memory. |

Set the allocator to use for array management. Arrays are always allocated by the IReader. That is, you cannot read data into an array slice (for example). Instead, a number of IArrayAllocator classes are available to manage memory allocation when reading array content. By default, an IReader will allocate each array from the heap. You can change that behavior by calling this method with an IArrayAllocator of choice. For instance, there is a BufferAllocator which will slice an array directly from the buffer where possible. Also available is the record-oriented SliceAllocator, which slices memory from within a pre-allocated heap area, and should be reset by the client code after each record has been read (to avoid unnecessary growth). See ArrayAllocator for more information. Reimplemented from IReader. Definition at line 229 of file AbstractReader.d. |
|
Set the configured IStringDecoder. These are intended to be used as a conversion mechanism between various character representations. They are also expected to be used for the process of applying character encodings. See IStringDecoder. Reimplemented from IReader. Definition at line 247 of file AbstractReader.d. References IStringDecoder::char16(), AbstractReader::StringDecoder::char16, IStringDecoder::char32(), AbstractReader::StringDecoder::char32, IStringDecoder::char8(), AbstractReader::StringDecoder::char8, and AbstractReader::string. |
|
Push the size (in bytes) to use for the next array-read. By default, array sizes are read from the input stream, so this is the means by which one may specify the size where the stream is not formatted in such a manner.

|
Read and return an integer from the input stream. This can be used to extract the length of a subsequent array. Reimplemented from IReader. Definition at line 287 of file AbstractReader.d. References AbstractReader::get(), and AbstractReader::pushed. |

Wait for something to arrive in the buffer. This may stall the current thread forever, although usage of SocketConduit will take advantage of the timeout facilities provided there. Reimplemented from IReader. Definition at line 306 of file AbstractReader.d. References IBuffer::get(). |
