Method Detail

createNumericConstraint

public static DVConstraint createNumericConstraint(int validationType,
                                                   int comparisonOperator,
                                                   java.lang.String expr1,
                                                   java.lang.String expr2)

Creates a number based data validation constraint. The text values entered for expr1 and expr2 can be either standard Excel formulas or formatted number values. If the expression starts with '=' it is parsed as a formula, otherwise it is parsed as a formatted number.

Parameters:

validationType - one of DataValidationConstraint.ValidationType.ANY, DataValidationConstraint.ValidationType.DECIMAL, DataValidationConstraint.ValidationType.INTEGER, DataValidationConstraint.ValidationType.TEXT_LENGTH

comparisonOperator - any constant from DataValidationConstraint.OperatorType enum

expr1 - date formula (when first char is '=') or formatted number value

expr2 - date formula (when first char is '=') or formatted number value

createFormulaListConstraint

public static DVConstraint createFormulaListConstraint(java.lang.String listFormula)

createExplicitListConstraint

public static DVConstraint createExplicitListConstraint(java.lang.String[] explicitListValues)

createTimeConstraint

public static DVConstraint createTimeConstraint(int comparisonOperator,
                                                java.lang.String expr1,
                                                java.lang.String expr2)

Creates a time based data validation constraint. The text values entered for expr1 and expr2 can be either standard Excel formulas or formatted time values. If the expression starts with '=' it is parsed as a formula, otherwise it is parsed as a formatted time. To parse formatted times, two formats are supported: "HH:MM" or "HH:MM:SS". This is contrary to Excel which uses the default time format from the OS.

Parameters:

comparisonOperator - constant from DataValidationConstraint.OperatorType enum

expr1 - date formula (when first char is '=') or formatted time value

expr2 - date formula (when first char is '=') or formatted time value

createDateConstraint

public static DVConstraint createDateConstraint(int comparisonOperator,
                                                java.lang.String expr1,
                                                java.lang.String expr2,
                                                java.lang.String dateFormat)

Creates a date based data validation constraint. The text values entered for expr1 and expr2 can be either standard Excel formulas or formatted date values. If the expression starts with '=' it is parsed as a formula, otherwise it is parsed as a formatted date (Excel uses the same convention). To parse formatted dates, a date format needs to be specified. This is contrary to Excel which uses the default short date format from the OS.

Parameters:

comparisonOperator - constant from DataValidationConstraint.OperatorType enum

expr1 - date formula (when first char is '=') or formatted date value

expr2 - date formula (when first char is '=') or formatted date value

dateFormat - ignored if both expr1 and expr2 are formulas. Default value is "YYYY/MM/DD" otherwise any other valid argument for SimpleDateFormat can be used
