createFromStream

public static DataTypeIf createFromStream(java.io.DataInputStream inputStream,
                                          IndexEntry indexEntry,
                                          long length)
                                   throws java.io.IOException

This method creates a rpm data type out of a input stream and an IndexEntry. The object must at the current position of the input stream. The length is only needed for string objects; the string objects will read length bytes of the input stream and will try to convert the data into a rpm data type.

Parameters:

inputStream - The input stream

indexEntry - The IndexEntry that should be read

length - The number of bytes to read for string objects

Returns:

One of the rpm data types coresponding with the type contained in the IndexEntry.

Throws:

java.io.IOException - if something was wrong during reading of the input stream
