Constructor Detail

BooleanType

public BooleanType(boolean item)

Creates a new boolean type.

Parameters:

item - to DER encode

BooleanType

public BooleanType(DERTag tag,
                   boolean item)

Creates a new boolean type.

Parameters:

tag - der tag associated with this type

item - to DER encode

Throws:

IllegalArgumentException - if the der tag is constructed

Method Detail

encode

public byte[] encode()

Description copied from interface: DEREncoder

Encode this object into it's DER type.

Specified by:

encode in interface DEREncoder

Returns:

DER encoded object

decode

public static boolean decode(ByteBuffer encoded)

Converts bytes in the buffer to a boolean by reading from the current position to the limit.

Parameters:

encoded - buffer containing DER-encoded data where the buffer is positioned at the start of boolean bytes and the limit is set beyond the last byte of integer data.

Returns:

decoded bytes as a boolean.

toBytes

public static byte[] toBytes(boolean b)

Converts the supplied boolean to a byte array.

Parameters:

b - to convert

Returns:

byte array
