                                              throws ExprValidationException

Returns the widener.

Parameters:

columnName - name of column

columnType - type of column

writeablePropertyType - property type

writeablePropertyName - propery name

allowObjectArrayToCollectionConversion - whether we widen object-array to collection

customizer - customization if any

engineURI - engine URI

statementName - statement name

Returns:

type widender

Throws:

ExprValidationException - if type validation fails
