public void writeDouble(double v)
                 throws java.io.IOException

Throws:

java.io.IOException

writeECPoint

public void writeECPoint(org.bouncycastle.math.ec.ECPoint v)
                  throws java.io.IOException

Throws:

java.io.IOException

writeFixedString

public void writeFixedString(java.lang.String v,
                             int length)
                      throws java.io.IOException

writeFloat

public void writeFloat(float v)
                throws java.io.IOException

Throws:

java.io.IOException

writeInt32

public void writeInt32(int v)
                throws java.io.IOException

Throws:

java.io.IOException

writeInt64

public void writeInt64(long v)
                throws java.io.IOException

Writes the given long (signed 64-bit integer) to the underlying output stream in little-endian order. The long's byte representation is its two's complement.

Parameters:

v - the value

Throws:

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

writeUInt32

public void writeUInt32(long v)
                 throws java.io.IOException

Writes the first (least-significant) 32 bits of the given long (signed 64-bit integer) to the underlying output stream in little-endian order. I.e. the byte output represents an unsigned 32-bit integer in the range [0, 2^32).

Parameters:

v - the value which needs to be in the range [0, 2^32).

Throws:

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

java.lang.IllegalArgumentException - if the arguments value does not lie in the interval [0, 2^32).

                               throws java.io.IOException

Throws:

java.io.IOException

writeSerializableVariableBytes

public void writeSerializableVariableBytes(java.util.List<? extends NeoSerializable> v)
                                    throws java.io.IOException

Throws:

java.io.IOException

writeSerializableFixed

                            throws java.io.IOException

Throws:

java.io.IOException

writeSerializableFixed

public void writeSerializableFixed(java.util.List<? extends NeoSerializable> v)
                            throws java.io.IOException

Throws:

java.io.IOException

writeUInt16

public void writeUInt16(int v)
                 throws java.io.IOException

Writes the first (least-significant) 16 bits of the given int (signed 32-bit integer) to the underlying output stream in little-endian order. I.e. the byte output represents an unsigned 16-bit integer in the range [0, 2^16).

Parameters:

v - the value which needs to be in the range [0, 2^16).

Throws:

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

java.lang.IllegalArgumentException - if the arguments value does not lie in the interval [0, 2^16).
