Method Detail

toBoolean

public static boolean toBoolean(Object value,
                EvaluationContext ctx)

Tries conversion of any value to a boolean (called a 'Logical Value' in Excel lingo)

toInteger

public static int toInteger(Object value,
            EvaluationContext ctx)

Tries conversion of any value to an integer

toDecimal

public static BigDecimal toDecimal(Object value,
                   EvaluationContext ctx)

Tries conversion of any value to a decimal

toString

public static String toString(Object value,
              EvaluationContext ctx)

Tries conversion of any value to a string

toDate

public static org.threeten.bp.LocalDate toDate(Object value,
                               EvaluationContext ctx)

Tries conversion of any value to a date

toDateTime

public static org.threeten.bp.ZonedDateTime toDateTime(Object value,
                                       EvaluationContext ctx)

Tries conversion of any value to a date

toDateOrDateTime

public static org.threeten.bp.temporal.Temporal toDateOrDateTime(Object value,
                                                 EvaluationContext ctx)

Tries conversion of any value to a date or a datetime

toTime

public static org.threeten.bp.OffsetTime toTime(Object value,
                                EvaluationContext ctx)

Tries conversion of any value to a time

toSame

public static org.apache.commons.lang3.tuple.Pair<Object,Object> toSame(Object value1,
                                                        Object value2,
                                                        EvaluationContext ctx)

Converts a pair of arguments to their most-likely types. This deviates from Excel which doesn't auto convert values but is necessary for us to intuitively handle contact fields which don't use the correct value type

toRepr

public static String toRepr(Object value,
            EvaluationContext ctx)

Converts a value back to its representation form, e.g. x -> "x"
