Method Details

overrideBlockToAvroObject

public Optional<BiFunction<Block,Integer,Object>> overrideBlockToAvroObject(org.apache.avro.Schema schema,
 Type type)
                                                                     throws AvroTypeException

Description copied from interface: AvroTypeManager

Extract and convert the object from the given block at the given position and return the Avro Generic Data forum. Type is either provided explicitly to the writer or derived from the schema using this interface.

Specified by:

overrideBlockToAvroObject in interface AvroTypeManager

Throws:

AvroTypeException

validateLogicalType

public static NativeLogicalTypesAvroTypeManager.ValidateLogicalTypeResult validateLogicalType(org.apache.avro.Schema schema)

fromBigEndian

public static long fromBigEndian(byte[] bytes)

Decode a long from the two's complement big-endian representation.

Parameters:

bytes - the two's complement big-endian encoding of the number. It must contain at least 1 byte. It may contain more than 8 bytes if the leading bytes are not significant (either zeros or -1)

Throws:

ArithmeticException - if the bytes represent a number outside the range [-2^63, 2^63 - 1]

fitBigEndianValueToByteArraySize

public static byte[] fitBigEndianValueToByteArraySize(long value,
 int byteSize)

fitBigEndianValueToByteArraySize

public static byte[] fitBigEndianValueToByteArraySize(Int128 value,
 int byteSize)

fitBigEndianValueToByteArraySize

public static byte[] fitBigEndianValueToByteArraySize(byte[] value,
 int byteSize)

Will resize big endian bytes to a desired array length while preserving the represented value.

Throws:

ArithmeticException - if conversion is not possible

padBigEndianToSize

public static byte[] padBigEndianToSize(Int128 toPad,
 int byteSize)

padBigEndianToSize

public static byte[] padBigEndianToSize(long toPad,
 int byteSize)

padBigEndianToSize

public static byte[] padBigEndianToSize(byte[] toPad,
 int byteSize)
