Class DataInputUTF8Decoder

java.lang.Object
  com.sun.squawk.util.DataInputUTF8Decoder

public final class DataInputUTF8Decoder
extends Object

This class provides one function for decoding a UTF-8 encoded string from a DataInput. This provides almost the same functionality as DataInputStream.readUTF(DataInput) except that it can be used to decode a UTF-8 string from a Java class file which differs from the "standard" UTF-8 format in that 0 is encoded in two bytes as opposed to one.

Method Summary

static String	readUTF(DataInput in, boolean isClassFile, boolean twoByteLength) Reads a UTF-8 encoded String from in.
static String	readUTF(DataInput in, boolean isClassFile, int utflen) Reads a UTF-8 encoded String from in.

Method Detail

readUTF

public static final String readUTF(DataInput in,
                                   boolean isClassFile,
                                   boolean twoByteLength)
                            throws IOException

Reads a UTF-8 encoded String from in.

Parameters:

in - a data input stream.

isClassFile - if true, then 0 is decoded from two bytes as opposed to one

twoByteLength - if true, then the length of the encoded string is given in two bytes as opposed to 4

Returns:

the decoded string

Throws:

IOException

                            throws IOException

Reads a UTF-8 encoded String from in.

Parameters:

in - a data input stream.
