ThriftDatumReader

protected ThriftDatumReader(Schema writer,

Method Detail

createEnum

protected Object createEnum(String symbol,
                            Schema schema)

Description copied from class: GenericDatumReader

Called to create an enum value. May be overridden for alternate enum representations. By default, returns a GenericEnumSymbol.

Overrides:

createEnum in class GenericDatumReader<T>

readInt

protected Object readInt(Object old,
                         Schema s,
                         Decoder in)
                  throws IOException

Description copied from class: GenericDatumReader

Called to read integers. Subclasses may override to use a different integer representation. By default, this calls Decoder.readInt().

Overrides:

readInt in class GenericDatumReader<T>

Throws:

IOException

newArray

protected Object newArray(Object old,
                          int size,
                          Schema schema)

Description copied from class: GenericDatumReader

Called to create new array instances. Subclasses may override to use a different array implementation. By default, this returns a GenericData.Array.

Overrides:

newArray in class GenericDatumReader<T>
