Method Detail

convertToLogicalType

public static Object convertToLogicalType(Object datum,
                                          Schema schema,
                                          LogicalType type,
                                          Conversion<?> conversion)

Convert a underlying representation of a logical type (such as a ByteBuffer) to a higher level object (such as a BigDecimal).

Parameters:

datum - The object to be converted.

schema - The schema of datum. Cannot be null if datum is not null.

type - The LogicalType of datum. Cannot be null if datum is not null.

conversion - The tool used to finish the conversion. Cannot be null if datum is not null.

Returns:

The result object, which is a high level object of the logical type. If a null datum is passed in, a null value will be returned.

Throws:

IllegalArgumentException - if a null schema, type or conversion is passed in while datum is not null.

convertToRawType

public static <T> Object convertToRawType(Object datum,
                                          Schema schema,
                                          LogicalType type,
                                          Conversion<T> conversion)

Convert a high level representation of a logical type (such as a BigDecimal) to the its underlying representation object (such as a ByteBuffer)

Parameters:

datum - The object to be converted.

schema - The schema of datum. Cannot be null if datum is not null.

type - The LogicalType of datum. Cannot be null if datum is not null.

conversion - The tool used to finish the conversion. Cannot be null if datum is not null.

Returns:

The result object, which is an underlying representation object of the logical type. If the input param datum is null, a null value will be returned.

Throws:

IllegalArgumentException - if a null schema, type or conversion is passed in while datum is not null.
