Java Utililty Methods Object to String

String castString(Object o)
cast String

return String.valueOf(o);

String castString(Object obj)
cast String

return castString(obj, "");

String castString(Object obj, String defaultValue)
cast String

return obj != null ? String.valueOf(obj) : defaultValue;

String castString(Object val)
cast String

try {
 return val != null ? val.toString() : "null";
} catch (Exception e) {
 return "<ERR: " + e.getMessage() + ">";

String castToString(Object inValue)
cast To String

return cast(inValue, (String) null);

String castToString(Object object)
Sometimes ELP's version of cast is misbehaving

return object == null ? null : object.toString();

String castToString(Object value)
cast To String

if (value == null) {
 return null;
return value.toString();

String[] castToStringArray(Object[] array)
EPL has embedded cast method, but it doesn't cover arrays

if (array != null) {
 String[] retArray = new String[array.length];
 int i = 0;
 for (Object element : array) {
 retArray[i] = element == null ? null : element.toString();
 i++;
 return retArray;
...

String objectToString(final Object value)
For Visual Studio compatibility.

if (value instanceof Double) {
 return doubleToString((Double) value);
} else {
 return value.toString();

String objectToString(Object a_Object)
Makes object to string if it is null then empty string "" is returned
Advantage of this is that it is handling nulls correctly

if (a_Object != null) {
 return a_Object.toString();
} else {
 return "";
