Description

The list of methods to do Object to Long are organized into topic(s).

Method

LongcastLong(Object o)
cast Long 
Long value = null;
if (o != null) {
    value = Long.parseLong(o.toString());
return value;
LongcastLong(Object o)
Casts a value to a double. 
if (o == null) {
    return null;
if (o instanceof Number) {
    return ((Number) o).longValue();
} else {
    try {
        return Long.valueOf(o.toString());
...
longcastLong(Object val)
cast Long 
return (val instanceof String) ? Long.parseLong(val.toString().trim()) : ((Number) val).longValue();
intcastLong2Int(long x)
cast Long Int 
if (x >= Integer.MAX_VALUE) {
    return Integer.MAX_VALUE;
} else if (x <= Integer.MIN_VALUE) {
    return Integer.MIN_VALUE;
return (int) x;
intcastLongtoUInt(long x)
cast Longto U Int 
return (int) (x & 0x00000000ffffffffL);
LongcastToLong(final String uid)
cast To Long 
try {
    return Long.decode(uid);
} catch (NumberFormatException nfe) {
    return null;
LongcastToLong(Object object)
Sometimes ELP's version of cast is misbehaving 
if (object != null) {
    if (object instanceof Long)
        return (Long) object;
    else
        return Long.valueOf(object.toString());
return null;
LongcastToLong(Object value)
cast To Long 
if (value == null) {
    return null;
if (value instanceof Number) {
    return ((Number) value).longValue();
if (value instanceof String) {
    String strVal = (String) value;
...
LongcastToLong(Object value)
cast To Long 
return (Long) value;
Long[]castToLongArray(Object[] array)
EPL has embedded cast method, but it doesn't cover arrays 
if (array != null) {
    Long[] retArray = new Long[array.length];
    int i = 0;
    for (Object element : array) {
        retArray[i] = element == null ? null : (Long) element;
        i++;
    return retArray;
