object ColumnCastUtil extends Arm
This class casts a column to another column if the predicate passed resolves to true. This method should be able to handle nested or non-nested types
At this time this is strictly a place for casting methods

ifTrueThenDeepConvertTypeAtoTypeB(cv: ColumnVector, dataType: DataType, predicate: (DataType, ColumnView) ⇒ Boolean, convert: (DataType, ColumnView) ⇒ ColumnView): ColumnVector
This method deep casts the input ColumnView to a new column if the predicate passed to this method resolves to true.
This method deep casts the input ColumnView to a new column if the predicate passed to this method resolves to true. Note: This method will also cast children of nested types to the given type if predicate succeeds
- cv
The column view that could potentially have a type to replace
- predicate
Condition on which to cast the column or child column view
- convert
Method used to convert the column view to a new column view
