Deconstructing the use of an unsafe pointer in the Swift library method; public init?(validatingUTF8 cString: UnsafePointer<CChar>) Purpose: Creates a new string by copying and validating the null-terminated UTF-8 data referenced by the given pointer. This initializer does not try to rep...

""" A [GFF parser script][1] in Python for [www.VigiLab.org][2] Description: - That performs buffered reading, and filtering (see: @filter) of .GFF input file (e.g. "[./toy.gff][3]") to keep only rows whose field (column) values are equal to "transcript...

There's two ways to create a ByteBuffer, where one can be subdivided again. If you have an already existing byte[], you can "wrap" it into a ByteBuffer to simplify processing: byte[] reqBuffer = new byte[BUFFER_SIZE]; int readBytes = socketInputStream.read(reqBuffer); final ByteBuffer ...

Given a ByteBuffer instance one can write primitive-type data to it using relative and absolute put. The striking difference is that putting data using the relative method keeps track of the index the data is inserted at for you, while the absolute method always requires giving an index to put the d...

ByteStrings and Buffers Okio is built around two types that pack a lot of capability into a straightforward API: ByteString is an immutable sequence of bytes. For character data, String is fundamental. ByteString is String's long-lost brother, making it easy to treat binary data as a value. This c...

DirectByteBuffer is special implementation of ByteBuffer that has no byte[] laying underneath. We can allocate such ByteBuffer by calling: ByteBuffer directBuffer = ByteBuffer.allocateDirect(16); This operation will allocate 16 bytes of memory. The contents of direct buffers may reside outside ...

Some of the log4net appenders are buffered appenders. These appenders will only log when a certain amount of messages are logged. Some samples are the SmtpAppender, RemotingAppender or the AdoNetAppender. These appenders have a setting BufferSize: <bufferSize value="100" /> This ...

Key Points :- used to created mutable (modifiable) string. Mutable :- Which can be changed. is thread-safe i.e. multiple threads cannot access it simultaneously. Methods :- public synchronized StringBuffer append(String s) public synchronized StringBuffer insert(int off...

For a convenient way to iterate through an arrayBuffer, you can create a simple iterator that implements the DataView methods under the hood: var ArrayBufferCursor = function() { var ArrayBufferCursor = function(arrayBuffer) { this.dataview = new DataView(arrayBuffer, 0); this.size = a...
