compareTypeSafe
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 classValue
- Parameters:
v
- the other valuemode
- the compare modeprovider
- the cast information provider- Returns:
- 0 if both values are equal, -1 if the other value is smaller, and 1 otherwise
-
getSQL
Description copied from interface:HasSQL
Appends the SQL statement of this object to the specified builder.- Parameters:
builder
- string buildersqlFlags
- formatting flags- Returns:
- the specified string builder
-
hashCode
public final int hashCode() -
getMemory
public int getMemory()Description copied from class:Value
Get the memory used by this object. -
equals
Description copied from class:Value
Check if the two values have the same hash code. No data conversion is made; this method returns false if the other object is not of the same class. For some values, compareTo may return 0 even if equals return false. Example: ValueDecimal 0.0 and 0.00.
