EOFErrorExample
class to show
the error generated if an attempt is made to read past the end of the available
data. This is accomplished with the following steps:
byteArr
and writes a Boolean
value of false
into the byte stream using writeBoolean()
. byteArr
is reset to 0
(start of the data stream).readBoolean()
. The
data stream now contains no data.readBoolean()
is called a second time and the EOFError is caught and passed to a trace()
statement, which outputs the error message associated with EOFError objects. package { import flash.display.Sprite; import flash.errors.EOFError; import flash.utils.ByteArray; public class EOFErrorExample extends Sprite { public function EOFErrorExample() { var byteArr:ByteArray = new ByteArray(); byteArr.writeBoolean(false); trace(byteArr.length); // 1 byteArr.position = 0; try { trace(byteArr.readBoolean()); // false } catch(e:EOFError) { trace(e); } try { trace(byteArr.readBoolean()); } catch(e:EOFError) { trace(e); // EOFError: Error #2030: End of file was encountered. } } } }
