public ByteArrayReader(byte[] data)
data - The byte array to be read.| Method Detail |
public long readInt()
throws java.io.IOException
Reads an integer from the byte array.
NOTE: This currently returns a long but only extracts 4 bytes. The reason behind this is that this class has been designed for SSH byte arrays; SSH uses unsigned integers but in java we do not have an unsigned integer type. To safely return the non negative value we must extract the byte information into a long to preserve the unsigned value. THIS WILL BE UPDATED SOON WITH THE UnsignedInteger class.
java.io.IOException - Description of the Exception
public static int previewInt(byte[] data,
int start)
data - The byte array to previewstart - The start position in the array
public java.lang.String readString()
throws java.io.IOException
java.io.IOException - Thrown of the data cannot be read
public byte[] readBinaryString()
throws java.io.IOException
java.io.IOException - Thrown if the data cannot be read
public java.math.BigInteger readBigInteger()
throws java.io.IOException
java.io.IOException - Thrown if the data cannot be read
