      • maximumNumericValues

        public Hashtable maximumNumericValues()
        Builds a table of maximum numeric values keyed on java class. This is used for type testing but might also be useful to end users attempting to sanitize values.

        NOTE: BigInteger & BigDecimal maximums are dependent upon their precision & Scale

        Overrides:
        maximumNumericValues in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

      • minimumNumericValues

        public Hashtable minimumNumericValues()
