Method Summary

static java.lang.Object cloneBean(java.lang.Object bean)
          Clone a bean based on the available property getters and setters, even if the bean class itself does not implement Cloneable.

static void copyProperties(java.lang.Object dest, java.lang.Object orig)
          Copy property values from the origin bean to the destination bean for all cases where the property names are the same.

static void copyProperty(java.lang.Object bean, java.lang.String name, java.lang.Object value)
          Copy the specified property value to the specified destination bean, performing any type conversion that is required.

static java.util.Map describe(java.lang.Object bean)
          Return the entire set of properties for which the specified bean provides a read method.

static java.lang.String[] getArrayProperty(java.lang.Object bean, java.lang.String name)
          Return the value of the specified array property of the specified bean, as a String array.

static int getDebug()

static java.lang.String getProperty(java.lang.Object bean, java.lang.String name)
          Return the value of the specified property of the specified bean, no matter which property reference format is used, as a String.
