Class ConvertMethodArgumentInterceptor

java.lang.Object
  org.equilibriums.aop.utils.interceptor.convert.ConvertMethodArgumentInterceptor

All Implemented Interfaces:

org.aopalliance.aop.Advice, org.aopalliance.intercept.Interceptor, org.aopalliance.intercept.MethodInterceptor

public class ConvertMethodArgumentInterceptor
extends Object
implements org.aopalliance.intercept.MethodInterceptor

Will take value from the property specified by getFromArgumentIndex() and getFromPropertyPath(), convert it using specified Converter and replace property specified by getToArgumentIndex() and getToPropertyPath().

The paths are defines according to org.apache.commons.lang.StringUtils#getProperty or org.apache.commons.lang.StringUtils#setProperty documentation.

For example given method "public String method1(String arg1, List arg2, Map arg3);

• To convert arg1 use "0" as getFromArgumentIndex(), null as getFromPropertyPath(), "0" as getToArgumentIndex() and null as getToPropertyPath().
• To convert first value in arg2 use "1" as getFromArgumentIndex(), [0] as getFromPropertyPath(), "1" as getToArgumentIndex() and [0] as getToPropertyPath().
• To convert first value in arg2 and put it in arg3 with key "key1" use "1" as getFromArgumentIndex(), [0] as getFromPropertyPath(), "2" as getToArgumentIndex() and [key1] as getToPropertyPath().
