Class MultiDelimiterInterpolatorFilterReaderLineEnding

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable, java.lang.Readable
    public class MultiDelimiterInterpolatorFilterReaderLineEnding
extends AbstractFilterReaderLineEnding
    A FilterReader implementation, that works with Interpolator interface instead of its own interpolation implementation. This implementation is heavily based on org.codehaus.plexus.util.InterpolationFilterReader.
    Since:
    1.0
