Method Detail

getSchema

public abstract Schema getSchema()

Description copied from interface: GenericContainer

The schema of this instance.

Specified by:

getSchema in interface GenericContainer

get

public abstract Object get(int field)

Description copied from interface: IndexedRecord

Return the value of a field given its position in the schema.

This method is not meant to be called by user code, but only by DatumWriter implementations.

Specified by:

get in interface IndexedRecord

put

public abstract void put(int field,
                         Object value)

Description copied from interface: IndexedRecord

Set the value of a field given its position in the schema.

This method is not meant to be called by user code, but only by DatumReader implementations.

Specified by:

put in interface IndexedRecord

getSpecificData

public SpecificData getSpecificData()

getConversion

public Conversion<?> getConversion(int field)

put

public void put(String fieldName,
                Object value)

Description copied from interface: GenericRecord

Set the value of a field given its name.

Specified by:

put in interface GenericRecord

get

public Object get(String fieldName)

Description copied from interface: GenericRecord

Return the value of a field given its name.

Specified by:

get in interface GenericRecord

getConversion

public Conversion<?> getConversion(String fieldName)

equals

public boolean equals(Object that)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

compareTo

public int compareTo(SpecificRecord that)

Specified by:

compareTo in interface Comparable<SpecificRecord>

toString

public String toString()

Overrides:

toString in class Object

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

readExternal

public void readExternal(ObjectInput in)
                  throws IOException

Specified by:

readExternal in interface Externalizable

Throws:

IOException

hasCustomCoders

protected boolean hasCustomCoders()

Returns true iff an instance supports the MessageEncoder.encode(D) and MessageDecoder.decode(java.io.InputStream) operations. Should only be used by SpecificDatumReader/Writer to selectively use customEncode(org.apache.avro.io.Encoder) and customDecode(org.apache.avro.io.ResolvingDecoder) to optimize the (de)serialization of values.

customEncode

public void customEncode(Encoder out)
                  throws IOException

Throws:

IOException

customDecode

public void customDecode(ResolvingDecoder in)
                  throws IOException

Throws:

IOException
