Constructor Details

BERTag

public BERTag(int tag,
 BERElement element,
 boolean implicit)

Constructs a tag element.

Parameters:

tag - tag value

element - ber element

implicit - tagged implicitly

BERTag

public BERTag(BERTagDecoder decoder,
 int tag,
 InputStream stream,
 int[] bytes_read)
       throws IOException

Constructs a tag element from an input stream.

Parameters:

decoder - decoder object for application-specific tags

tag - tag value; already stripped from stream

stream - source

bytes_read - array of 1 int; incremented by number of bytes read from stream

Throws:

IOException - failed to construct

Method Details

getValue

public BERElement getValue()

Gets the element from the tagged object.

Returns:

BER element.

setImplicit

public void setImplicit(boolean value)

Sets the implicit tag. If it is an implicit tag, the next element tag can be omitted (it will not be sent to a stream or buffer).

Parameters:

value - implicit flag

write

public void write(OutputStream stream)
           throws IOException

Sends the BER encoding directly to a stream.

Specified by:

write in class BERElement

Parameters:

stream - output stream

Throws:

IOException - failed to send

getType

public int getType()

Gets the element type.

Specified by:

getType in class BERElement

Returns:

element type.

getTag

public int getTag()

Gets the element tag.

Returns:

element tag.

toString

public String toString()

Gets the string representation.

Specified by:

toString in class BERElement

Returns:

string representation of tag.
