EOFError

Package	flash.errors
Class	public dynamic class EOFError
Inheritance	EOFError IOError Error Object

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.0, Flash Player 9, Flash Lite 4

An EOFError exception is thrown when you attempt to read past the end of the available data. For example, an EOFError is thrown when one of the read methods in the IDataInput interface is called and there is insufficient data to satisfy the read request.

Examples How to use this example

EOFErrorExample.as

The following example uses the 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:

The constructor creates a ByteArray object byteArr and writes a Boolean value of false into the byte stream using writeBoolean().
The position of byteArr is reset to 0 (start of the data stream).
A single byte is removed from the data stream using readBoolean(). The data stream now contains no data.
Within an error handling code segment set to catch EOFError objects, 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.
            }
        }
    }
