@ConstructorArgs inside @Case

[GoogleCodeExporter]

If @ConstructorArgs would be defined inside the @Case annotation then it would 
be possible to have different constructors based on different @Case in the 
@TypeDescriminator...

According to the documentation the @ConstructorArgs corresponds to 
<constructor> which is inside the <resultMap> which corresponds to @Results.

Example:
    @TypeDiscriminator(column = "TYPE", cases = {
            @Case(value = "1", type = Character.class, constructorArgs = {
                    @Arg(),
                    @Arg
            })
    })

I checked out the source code and I reckon it is not too much work to add this. 
Of course this is not included any time needed to perform the testing.

The simple changes that will enable the feature:

Case.java

package org.apache.ibatis.annotations;

import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface Case {
 public abstract String value();
 public abstract Class<?> type();
 public abstract Result[] results() default {};
 public abstract Arg[] constructArgs() default {};
}

In mapperAnnotationBuilder.java:

add line +/-185:
               applyConstructorArgs( c.constructArgs(), resultType, resultMappings );
