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.

A one-byte type marker describes the type of the encoded data that follows.

The length of the ByteArray object, in bytes. Actionscrupt ByteArray class includes several methods that make it easier to read from and write to a data stream. It does the following:. For example, the following code writes a string to a ByteArray and afterward the position property points to the byte immediately following the string in the ByteArray: Vectors can be further optimized by declaring a fixed length. The entire byte array is compressed. If toJSON returns a string, stringify does not recurse and continues its traversal.

I mean, can we not write further into the ByteArray once a null byte has been written? Possible uses of the ByteArray class include the following: Examine each line of the code below and the impact it has on the ByteArray: After the call, the length property of the ByteArray is set to the new length.

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. Creates a ByteArray instance representing a packed array of bytes, so that you can use the methods and properties in this class to optimize your data storage and stream. Indicates whether an instance of the Object class is in the prototype chain of the object specified as the parameter. Consequently those bytes are identical to the result of calling compress air.

Reads the number of data bytes, specified by the length parameter, from the byte stream. Writes an IEEE double-precision bit floating-point number to the byte stream.

Likewise, a read operation increments the position property by the number of bytes read. Throws IOError — The data is not valid compressed data; it was not compressed with the same compression algorithm used to compress.

While this is legal with Array: Doesn’t it have support for trace?

Writes a Boolean value. The supported algorithms include the following:. The encoded data follows the type marker unless the marker represents a single possible value, such as null or true or false, in which case nothing else is encoded.

ActionScript 3 fundamentals: Vectors and ByteArrays

While adding data with push and removing it with pop is an effective way to manipulate the end of variable sized vectors, they are most commonly manipulated and accessed via index. If you read one byte, the position moves forward by one. Write actonscript double-precision floating-point equivalent of the mathematical value of actiobscript. A reference to the class object or constructor function for a given object instance.

If the length parameter is omitted, the default length of 0 is used; the method writes the entire buffer starting at offset.

Compresses the byte array. 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.

EOFError — There is not sufficient data available to read.

ActionScript – Null Bytes in ByteArray – Stack Overflow

String — The string representation bytearrqy the byte array. Some computers store the most significant byte of the number first, in the lowest memory address, and others store the least significant byte first.

The entire byte array is compressed. Setting this property to true only affects subsequent code that passes this byte array to a worker. Returns Number — A double-precision bit floating-point number.
