readEncodedECPoint

public byte[] readEncodedECPoint()
                          throws DeserializationException

Tries to read an encoded EC point from the underlying stream.

Returns:

the encoded EC point byte array

Throws:

DeserializationException - if an the stream does not contain an EC point or an IOException occurs.

readECPoint

public org.bouncycastle.math.ec.ECPoint readECPoint()
                                             throws java.io.IOException

Throws:

java.io.IOException

readFloat

public float readFloat()
                throws java.io.IOException

Throws:

java.io.IOException

readInt

public int readInt()
            throws java.io.IOException

Throws:

java.io.IOException

readUInt16

public int readUInt16()
               throws java.io.IOException

Reads a 16-bit unsigned integer from the underlying input stream.

Since Java does not support unsigned numeral types, the 16-bit short is represented by a int.

Returns:

the 16-bit unsigned integer as a normal Java int.

Throws:

java.io.IOException - if an I/O exception occurs.

readUInt32

public long readUInt32()
                throws java.io.IOException

Reads a 32-bit unsigned integer from the underlying input stream.

Since Java does not support unsigned numeral types, the unsigned integer is represented by a long.

Returns:

the 32-bit unsigned integer.

Throws:

java.io.IOException - if an I/O exception occurs.

readInt64

public long readInt64()
               throws java.io.IOException

Reads a 64-bit signed integer from the underlying input stream.

Returns:

the 34-bit unsigned integer represented as a long.

Throws:

java.io.IOException - if an I/O exception occurs.
