Constructor Details

NewAttributeBands

public NewAttributeBands(Segment segment,
 AttributeLayout attributeLayout)
                  throws IOException

Throws:

IOException

Method Details

getBackwardsCallCount

public int getBackwardsCallCount()

getCodec

public BHSDCodec getCodec(String layoutElement)

Returns the BHSDCodec that should be used for the given layout element.

Parameters:

layoutElement - TODO

Returns:

the BHSDCodec that should be used for the given layout element.

parseAttributes

public List<Attribute> parseAttributes(InputStream in,
 int occurrenceCount)
                                throws IOException,
Pack200Exception

Parse the bands relating to this AttributeLayout and return the correct class file attributes as a List of Attribute.

Parameters:

in - parse source.

occurrenceCount - TODO

Returns:

Class file attributes as a List of Attribute.

Throws:

IOException - If an I/O error occurs.

Pack200Exception - If a Pack200 semantic error occurs.

read

public void read(InputStream in)
          throws IOException,
Pack200Exception

Description copied from class: BandSet

Reads the input stream.

Specified by:

read in class BandSet

Parameters:

in - the stream to read.

Throws:

IOException - if a problem occurs during reading from the underlying stream.

Pack200Exception - if a problem occurs with an unexpected value or unsupported Codec.

setBackwardsCalls

public void setBackwardsCalls(int[] backwardsCalls)
                       throws IOException

Once the attribute bands have been read the callables can be informed about the number of times each is subject to a backwards call. This method is used to set this information.

Parameters:

backwardsCalls - one int for each backwards callable, which contains the number of times that callable is subject to a backwards call.

Throws:

IOException - If an I/O error occurs.

unpack

public void unpack()
            throws IOException,
Pack200Exception

Description copied from class: BandSet

Unpacks this instance.

Specified by:

unpack in class BandSet

Throws:

IOException - if a problem occurs during reading from the underlying stream.

Pack200Exception - if a problem occurs with an unexpected value or unsupported Codec.
