Write array to ByteArray: ByteArray «Development «Flash / Flex / ActionScript. is it possible to write past the null byte into the ByteArray()?. Of course it is. ByteArray — is a chunk of raw data. You can write whatever you like there, and you. As the name suggests, a byte array allows you to work with binary data by storing it Most of the uses of byte arrays in ActionScript are fairly specialized, but an.

Indicates whether an instance of the Object class is in the prototype chain of the object specified as the parameter. One of the simplest things we can do with a ByteArray is to write a value into it. The position property is set to 0.
String; public var age: See also uncompress CompressionAlgorithm. For a complete list, see Supported Character Sets. First, you will bytearday that you used writeBoolean when you added data to the ByteArray.
If you subsequently pass this byte array to a worker, its underlying memory is copied as with any ByteArray object whose shareable property is false. Boolean — A Boolean value determining which byte is written.
Reads a Boolean value from the byte stream. The endian property Computers can differ in how they store multibyte numbers, that is, numbers actionscripr require more than 1 byte of memory to store them. The high 16 bits are ignored.
ActionScript 3 fundamentals: Vectors and ByteArrays
It is extremely powerful and extremely fast; however, it requires a firm byteafray of data types and serialization to use effectively.
String Changes or reads the byte order for the data; either Endian. ByteArray — The ByteArray object to read data into. In order to decode data compressed in a format that uses the deflate compression algorithm, such as data in gzip or zip format, it will not work to call uncompress CompressionAlgorithm.
The length of the UTF-8 string in bytes is written first, as a bit integer, followed by the bytes representing the characters of the string. The number of bytes of data available for reading from the current position in the byte array to the end of the array.
First, you must separate the metadata from the compressed data, and you can then use the deflate format to decompress the compressed data. String — A string composed of the UTF-8 bytes of the specified length. This means that when you read it, it will be of type Object and you byteagray not be able to cast it back to its correct type. You specify a compression algorithm by passing a value defined in the CompressionAlgorithm class as the algorithm parameter.
Valid values are defined as constants in the CompressionAlgorithm class. This is the point at which the next call to a read method starts reading or a write method starts writing. String Returns the string representation of this object, formatted according to locale-specific conventions.
The value is a constant from the ObjectEncoding class.
Likewise, a read operation increments the position property by the number of bgtearray read. The entire byte array is compressed. Nox Noctis 3, 11 Neon Flash 1, 8 37 The zlib compressed data format is described at http: Vectors must be dense.
ActionScript – Null Bytes in ByteArray – Stack Overflow
As the last trace statement shows, person1 is a copy of the original person object, not a reference to it. The example also displays the value of the objectEncoding property along with a header for the contents of the order file. Returns uint — A bit unsigned integer between 0 and For example, this vector will hold have a space for each day of the week.
IOError — The data is not valid compressed data; it was not compressed with the same compression algorithm used to compress. String — The string representation of the byte array. More examples Reading and writing a ByteArray. String Reads a sequence of UTF-8 bytes specified by the length parameter from the byte stream and returns a string. The returned value is in the range 0 to To read the data back from the ByteArray, you must first reset the position to where the Person object begins, in this case position 0.
Certain bytes contain metadata about the compressed data, while other bytes contain the actual compressed version of the original ByteArray data.
If it returns an object, stringify recurses into that object. The repeating data pattern makes it possible to read the array with a loop.
