Constructor Detail

TarEntryEnumerator

public TarEntryEnumerator(TarInputStream tis)

Construct an instance given a TarInputStream. This method is package private because it is not initially foreseen that an instance of this class should be constructed from outside the package. Should it become necessary to construct an instance of this class from outside the package in which it exists then the constructor should be made protected and an empty subclass should be written in the other package.

Parameters:

tis - the TarInputStream on which this enumeration has to be based.
