+<pre>public abstract class <span class="typeNameLabel">SimpleEvalFunc<T></span>
+extends org.apache.pig.EvalFunc<T></pre>
+<div class="block">Uses reflection to makes writing simple wrapper Pig UDFs easier.
+
+ For example, writing a simple string trimming UDF might look like
+ this:
+ <pre>
+ <code>
+ public class TRIM extends EvalFunc<String>
+ {
+ public String exec(Tuple input) throws IOException
+ {
+ if (input.size() != 1)
+ throw new IllegalArgumentException("requires a parameter");
+
+ try {
+ Object o = input.get(0);
+ if (!(o instanceof String))
+ throw new IllegalArgumentException("expected a string");
+
+ String str = (String)o;
+ return (str == null) ? null : str.trim();
+ }
+ catch (Exception e) {
+ throw WrappedIOException.wrap("error...", e);
+ }
+ }
+ }
+ </code>
+ </pre>
+ There is a lot of boilerplate to check the number of arguments and
+ the parameter types in the tuple.
+
+ Instead, with this class, you can derive from SimpleEvalFunc and
+ create a <code>call()</code> method (not exec!), just specifying the
+ arguments as a regular function. The class handles all the argument
+ checking and exception wrapping for you. So your code would be:
+ <pre>
+ <code>
+ public class TRIM2 extends SimpleEvalFunc<String>
+ {
+ public String call(String s)
+ {
+ return (s != null) ? s.trim() : null;
+ }
+ }
+ </code>
+ </pre>
+
+ An example of this UDF in action with Pig:
+ <pre>
+ <code>
+ grunt> a = load 'test' as (x:chararray, y:chararray); dump a;
+ (1 , 2)
+
+ grunt> b = foreach a generate TRIM2(x); dump b;
+ (1)
+
+ grunt> c = foreach a generate TRIM2((int)x); dump c;
+ datafu.pig.util.TRIM2(java.lang.String): argument type
+ mismatch [#1]; expected java.lang.String, got java.lang.Integer
+
+ grunt> d = foreach a generate TRIM2(x, y); dump d;
+ datafu.pig.util.TRIM2(java.lang.String): got 2 arguments, expected 1.
+ </code>
