public CVCObject(CVCTagEnum tag)

Constructor taking a tag

Parameters:

tag -

Method Detail

getTag

public CVCTagEnum getTag()

Returns the tag

Returns:

getParent

public AbstractSequence getParent()

Returns parent, that is, the AbstractSequence that contains this object (if any)

Returns:

setParent

public void setParent(AbstractSequence parent)

Sets the parent

Parameters:

parent -

encode

protected abstract int encode(DataOutputStream out)
                       throws IOException

Writes this object as a DER-encoded byte array to 'out'

Returns:

number of written bytes

Throws:

IOException

encodeLength

protected static byte[] encodeLength(int lenValue)

DER-encodes field length according to ITU-T X.690.

Parameters:

lenValue -

Returns:

decodeLength

protected static int decodeLength(DataInputStream in)

trimByteArray(byte[])

toByteArray

protected static byte[] toByteArray(Long longVal)

Converts a Long to a trimmed byte array.

Parameters:

longVal -

Returns:

See Also:

trimByteArray(byte[])

trimByteArray

protected static byte[] trimByteArray(byte[] data)

Trims a byte array meaning that leading bytes containing zeros have been removed. However, if 'longVal' is zero then the array contains one zero.

Parameters:

data -

Returns:

getAsText

public String getAsText()

Same as getAsText("", true).

Returns:

getAsText

public String getAsText(boolean showTagNo)

Same as getAsText("", boolean).

Parameters:

showTagNo -

Returns:

getAsText

public String getAsText(String tab)

Same as getAsText(String, true).

Parameters:

tab -

Returns:

getAsText

public String getAsText(String tab,
                        boolean showTagNo)

Creates a textual representation of this object's tag. Subclasses should call this method and then concatenate with the textual representation of the subclasses' value.

Parameters:

tab - supply some whitespace if indentation is wanted

showTagNo - if 'true' then the hex tag value is printed also

Returns:
