Method Detail

firstIndexOf

int firstIndexOf(@NonNull
                 CqlIdentifier id)

Returns the first index where a given identifier appears (depending on the implementation, identifiers may appear multiple times).

Throws:

IllegalArgumentException - if the id is invalid.

getType

@NonNull
DataType getType(@NonNull
                          CqlIdentifier id)

Returns the CQL type of the value for the first occurrence of id.

If you want to avoid the overhead of building a CqlIdentifier, use the variant of this method that takes a string argument.

Throws:

IllegalArgumentException - if the id is invalid.
