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

Method Details

getTag

public int getTag()
Gets the element tag.

Returns:
element tag.

getType

public int getType()
Gets the element type.
Overrides:
getType in interface BERElement

Returns:
element type.

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

toString

public String toString()
Gets the string representation.
Overrides:
toString in interface BERElement

Returns:
string representation of tag.

write

public void write(OutputStream stream)
            throws IOException
Sends the BER encoding directly to a stream.
Overrides:
write in interface BERElement

Parameters:
stream - output stream
