Class APDU_boolean

java.lang.Object
  ds.ov2.util.APDU_boolean

All Implemented Interfaces:

APDU_Serializable

public class APDU_boolean
extends Object
implements APDU_Serializable

APDU_Serializable wrapper around a boolean. The boolean is encoded as one byte, which is either 0 or 1, as every C programmer would expect.

CPP Preprocessing

This class uses the following cpp defines: PACKAGE, PUBLIC, ASSERT

Execution Environment:

host, card

Field Summary

boolean

value The boolean.

Constructor Summary

APDU_boolean()
Constructor that leaves value in an unspecified state.

APDU_boolean(boolean b)
Initialize value with b.

Method Summary

short	from_byte_array(short len, short this_index, byte[] byte_array, short byte_index) Deserialize the boolean.
boolean	is_compatible_with(Object o) Compatibility check for the OV-chip protocol layer.
short	size() Size of the boolean for the OV-chip protocol layer, see APDU_Serializable.size().
short	to_byte_array(short len, short this_index, byte[] byte_array, short byte_index) Serialize the boolean.

Field Detail

value

public boolean value

The boolean. It's value might freely be changed from the outside.

Constructor Detail

APDU_boolean

public APDU_boolean(boolean b)

Initialize value with b.

Parameters:

b - value for the field value

APDU_boolean

public APDU_boolean()

Constructor that leaves value in an unspecified state.

Method Detail

size

public short size()

Size of the boolean for the OV-chip protocol layer, see APDU_Serializable.size().

Specified by:

size in interface APDU_Serializable

Returns:

1

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 compatibel to any other APDU_boolean.

Specified by:

is_compatible_with in interface APDU_Serializable

Parameters:

o - actual argument or result

Returns:

true if o is an APDU_boolean

to_byte_array

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

Serialize the boolean. 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 the boolean. 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.
