Method Summary

Modifier and TypeMethod and Description
public static String

Returns:

String representation of the form className(p1=value,p2=value,...)
beanToString(Object bean)

Utility method to create a simple String representation of a JavaBean Object by showing all properties p which can be called by getP() on the Object.

public static <E> E[]
concat(final E[] array1, final E[] array2, final Class<E> itemClass)

public static boolean
isNullOrEmpty(Object[] array)

public static boolean

Returns:

true if either o1==o2 or (o1!=null and o1.equals(o2))
nullSafeEquals(Object o1, Object o2)

Checks equality of two Objects, allowing the case where o1==o2==null to return true.

public static String
safeToString(Object object)

Convenience toString() method that can be applied safely to a null Object, yielding null.

public static boolean nullSafeEquals(Object o1, Object o2)

Checks equality of two Objects, allowing the case where o1==o2==null to return true. The equals() method on o2 should be compatible with equality.

Returns:boolean

true if either o1==o2 or (o1!=null and o1.equals(o2))
