<H2><A name="filterreaderset">FilterReaderSet</A></H2>

<P>FilterReaderSets are groups of FilterReaders. FilterReaderSets can appear
inside tasks that support this feature. <BR>FilterReaderSets are used for
filtering file contents read in by tasks like LoadFile, etc.<BR>

Each FilterReaderSet is composed of nested <a name="filterreader">FilterReader</a> elements.

<H2>FilterReader</H2>

A FilterReader element must be supplied with a class name as
an attribute value. The class resolved by this name must
extend java.io.FilterReader. If the custom filter reader
needs to be parameterized, it must implement
org.apache.tools.type.Parameterizable.
