Field Detail

value

public short value

The wrapped short value.

Constructor Detail

APDU_short

public APDU_short()

Default initialization.

APDU_short

public APDU_short(short s)

Initialize to s.

Parameters:

s - short to wrap

APDU_short

public APDU_short(int i)

Initialize to i. Asserts that i fits into a short.

Only available if JAVACARD_APPLET is undefined.

Parameters:

i - value to wrap

Method Detail

copy

public void copy(int i)

Copy i into value. Asserts that i fits into a short.

Only available if JAVACARD_APPLET is undefined.

Parameters:

i - value to wrap

size

public short size()

Size in bytes necessary to send or receive this object via the OV-chip protocol layer, see APDU_Serializable.size().

Specified by:

size in interface APDU_Serializable

Returns:

2

is_compatible_with

public boolean is_compatible_with(Object o)

Compatibility check for the OV-chip protocol layer. See the compatibility check explanations and also APDU_Serializable.is_compatible_with.

This object is compatible with any other instance of APDU_short.

Specified by:

is_compatible_with in interface APDU_Serializable

Parameters:

o - actual argument or result

Returns:

true if o is an instance of APDU_short

to_byte_array

public short to_byte_array(short len,
                           short this_index,
                           byte[] byte_array,
                           short byte_index)

Serialize this short. See APDU_Serializable.to_byte_array.

Specified by:

to_byte_array in interface APDU_Serializable

Parameters:

len - available space in byte_array

this_index - number of bytes that have already been written in preceeding calls

byte_array - data array to serialize the state into

byte_index - index in byte_array

Returns:

the number of bytes actually written, except for the case where serialization finished by writing precisely len bytes, in this case len + 1 is returned.

from_byte_array

public short from_byte_array(short len,
                             short this_index,
                             byte[] byte_array,
                             short byte_index)

Deserialize this short. See APDU_Serializable.from_byte_array.

Specified by:

from_byte_array in interface APDU_Serializable

Parameters:

len - available data in byte_array

this_index - number of bytes that have already been read in preceeding calls

byte_array - data array to deserialize from

byte_index - index in byte_array

Returns:

the number of bytes actually read, except for the case where deserialization finished by reading precisely len bytes, in this case len + 1 is returned.
