Method Summary

All Methods Instance Methods Concrete Methods Deprecated Methods
Modifier and Type	Method	Description
`TypeValuePair`	`convertTo(Type targetType, TypeValuePair valuePair)`	Checks whether the target type would accept the specified value object and value type. This method is called for auto conversion of fonction parameters using the conversion type declared by the function metadata.
`ArrayCallback`	`convertToArray(Type type, java.lang.Object value)`
`java.util.Date`	`convertToDate(Type type1, java.lang.Object value)`	Converts the object of the given type into a date.
`java.lang.Boolean`	`convertToLogical(Type type1, java.lang.Object value)`	Converts the object of the given type into a boolean.
`java.lang.Number`	`convertToNumber(Type sourceType, java.lang.Object value)`	converts the object of the given type into a number.
`NumberSequence`	`convertToNumberSequence(Type type, java.lang.Object value, boolean strict)`	Converts the given (type,value) pair into a numeric sequence.
`Sequence`	`convertToSequence(Type type, java.lang.Object value)`
`java.lang.String`	`convertToText(Type type1, java.lang.Object value)`	(This conversion is used by the operator implementations.)
`ExtendedComparator`	`getComparator(Type type1, Type type2)`	Returns an comparator for the given types.
`Type`	`guessTypeOfObject(java.lang.Object o)`
`void`	`initialize(Configuration configuration, FormulaContext formulaContext)`	Deprecated. Use the single-argument function instead.
`void`	`initialize(FormulaContext formulaContext)`
