parseReferences

public String[] parseReferences(String name,
 InputStream in,
 BHSDCodec codec,
 int count,
 String[] reference)
                         throws IOException,
Pack200Exception

Parses count references from in, using codec to decode the values as indexes into reference (which is populated prior to this call). An exception is thrown if a decoded index falls outside the range [0..reference.length-1].

Parameters:

name - the band name

in - the input stream to read from

codec - the BHSDCodec to use for decoding

count - the number of references to decode

reference - the array of values to use for the references

Returns:

Parsed references.

Throws:

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

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

parseReferences

public String[][] parseReferences(String name,
 InputStream in,
 BHSDCodec codec,
 int[] counts,
 String[] reference)
                           throws IOException,
Pack200Exception

Parses count references from in, using codec to decode the values as indexes into reference (which is populated prior to this call). An exception is thrown if a decoded index falls outside the range [0..reference.length-1]. Unlike the other parseReferences, this post-processes the result into an array of results.

Parameters:

name - TODO

in - the input stream to read from

codec - the BHSDCodec to use for decoding

counts - the numbers of references to decode for each array entry

reference - the array of values to use for the references

Returns:

Parsed references.

Throws:

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

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