getBoolean in class Value

compareTypeSafe

public int compareTypeSafe(Value o,
                  CompareMode mode)

Description copied from class: Value

Compare this value against another value given that the values are of the same data type.

Specified by:

compareTypeSafe in class Value

Parameters:

o - the other value

mode - the compare mode

Returns:

0 if both values are equal, -1 if the other value is smaller, and 1 otherwise

hashCode
