  oracle.javatools.db.datatypes.NumericDataType.MinMaxValue

Enclosing class:

NumericDataType

public static class NumericDataType.MinMaxValue
extends java.lang.Object

public static class MinMaxValue defines the minimum and maximum value range of integer and floating-point numbers for use by NumericDataType.validateDefaultValue(). For integers that can be signed, minValue is the largest negative number, and maxValue the largest positive number. For unsigned integers, minValue is usually zero and maxValue the largest positive number. For floating-point numbers, minValue is the smallest positive number, and maxValue the largest positive number.

Field Detail

SIGNED_INT

public static final int SIGNED_INT

Valid values for valueType argument of constructor. Determines how a MinMaxValue is interpreted by NumericDataType.validateDefaultValue(). SIGNED_INT means a default value will be compared with the supplied minValue and maxValue, unless the datatype usage includes an UNSIGNED qualifier (e.g. mySQL and Sybase Adaptive Server Anywhere integers), when it will be compared with 0 .. (maxValue*2)-1. UNSIGNED_INT means the default value is compared with the minValue and maxValue only, e.g. Sybase Adaptive Server Anywhere TINYINT, which is always treated as unsigned, regardless of whether the datatype usage includes the UNSIGNED qualifier. FLOAT means that mainValue and maxValue are treated as floating point numbers. minValue should be the smallest positive value and maxValue the largest positive value. The NumericDataType class computes the negative minValue and maxValue from the positive values.
