ACTIONSCRIPT BYTEARRAY PDF

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.

Reads a multibyte string of specified length from the byte stream using the specified character set.

For example, you could set the position to four and read the Boolean directly:. The low 8 bits of the parameter are used. In ActionScript 3, a vector index begins at 0, meaning the first element of the vector is the 0th element. Returns Number — A single-precision bit floating-point number.

If it fails to find the value, it returns a PI ; trace byteArr.

ActionScript 3 fundamentals: Vectors and ByteArrays

Beginning with Flash Player When you read from or write to a ByteArray, the method that you use updates the position property to point to the location immediately following the last byte that was read or written. Examine each line of the actuonscript below and the impact it has on the ByteArray: When an object is written to or read from binary data, the objectEncoding value is used to determine whether the ActionScript 3.

The returned value is in the range to Writes a byte to the byte stream.

The default value of 0 causes all available data to be read. String; actionnscript var lastName: For example, a value for the charSet parameter, as in myTest.

Likewise, in order to decode data compressed in a format such as gzip or zip, you can’t simply call uncompress CompressionAlgorithm. One of elements simply contains a null value. For example, a value for the charSet parameter, as in myTest.

The byte array must have been compressed using the same algorithm. Returns Number — A single-precision bit floating-point number. Possible character set strings include “shift-jis””cn-gb””iso” actionscriot, and others.

However, the result from compress air. Writes a sequence of length bytes from the specified byte array, bytesstarting offset zero-based index bytes into the byte stream.

Reading and writing a ByteArray

This method simply gives Flash Player a convenient string to use as an alias for this class. The following example compresses a ByteArray called bytes using the lzma algorithm: The method returns the new length of the vector after the new item s actioonscript been added.

String — A string composed of the UTF-8 bytes of the specified length. String — The string representation of the byte array. The number of bytes of data available for reading from the current position in the byte array to the end of the array.

Adobe Flash Platform * Reading and writing a ByteArray

Likewise, in order to decode data compressed in a format such as gzip or zip, you can’t simply call uncompress air. Writes a bit integer to the byte stream. Decompressing the ByteArray is accomplished by calling the corresponding inflate method.

The print function might however use it as a string terminator. Boolean — A Boolean value determining which byte is written. Returns String — The string representation of the byte array. See also uncompress CompressionAlgorithm. After the call, the length property of the ByteArray is set to the new length.

That length property corresponds to the number of elements stored in bytewrray vector at any given time.
