The bytearray class is a mutable sequence of integers in the range 0 <= x < 256. It has most of the usual methods of mutable sequences, described in Mutable Sequence Types, as well as most methods that the bytes type has, see Bytes and Bytearray Operations. The optional source paramete...

The optional source parameter can be used to initialize the array in a few different ways: If it is a string, you must also give the encoding (and optionally, errors) parameters; bytearray() then converts the string to bytes using str.encode(). If it is an integer, the array will ha...
Return a new array of bytes. Thebytearrayclass is a mutable sequence of integers in the range 0 <= x < 256. It has most of the usual methods of mutable sequences, described in Mutable Sequence Types, as well as most methods that thebytestype has, see Bytes and Bytearray Operations. ...
ByteArray atomicCompareAndSwapLength(expectedLength:int, newLength:int):int 在单一的原子操作中,将此字节数组的长度与所提供的一个值进行比较,如果它们匹配,则更改此字节数组的长度。 ByteArray clear():void 清除字节数组的内容,并将 length 和 position 属性重置为 0。 ByteArray compress(algorithm:String):vo...
newarray instruction (§newarray) enables creation of boolean arrays. Arrays of type boolean are accessed and modified using the byte array instructions baload and bastore (§baload, §bastore). In Oracle’s Java Virtual Machine implementation, boolean arrays in the Java programming language are...
Here the string “Python” is encoded using the “utf-8” encoding and then passed into the bytearray. How does encoding work? As we know computers treat everything as 0’s and 1’s. So to represent the letter ‘A’ we can use the byte 0x41, ‘B’ with 0x42, and so on as sh...
classbytearray([source[,encoding[,errors]]]) 该内置函数本质上是bytearray类的构造函数,用于创建一个 bytearray 实例。bytearray 实例是一个由字节(8-bits 无符号)构成的可变序列,并拥有大多数可变序列的常见方法[详见:Mutable Sequence Types],并且还包含bytes类型中的大多数方法[详见:Bytes and Bytearray Opera...
