Method Detail

copy

public Decimal copy(Decimal from)

Description copied from interface: Serializer

Creates a deep copy of the given element in a new element.

Specified by:

copy in interface Serializer<Decimal>

Parameters:

from - The element reuse be copied.

Returns:

A deep copy of the element.

serialize

public void serialize(Decimal record,
                      DataOutputView target)
               throws IOException

Description copied from interface: Serializer

Serializes the given record to the given target output view.

Specified by:

serialize in interface Serializer<Decimal>

Parameters:

record - The record to serialize.

target - The output view to write the serialized data to.

Throws:

IOException - Thrown, if the serialization encountered an I/O related error. Typically raised by the output view, which may have an underlying I/O channel to which it delegates.

deserialize

public Decimal deserialize(DataInputView source)
                    throws IOException

Description copied from interface: Serializer

De-serializes a record from the given source input view.

Specified by:

deserialize in interface Serializer<Decimal>

Parameters:

source - The input view from which to read the data.

Returns:

The deserialized element.

Throws:

IOException - Thrown, if the de-serialization encountered an I/O related error. Typically raised by the input view, which may have an underlying I/O channel from which it reads.

serializeToString

public String serializeToString(Decimal record)

Description copied from interface: Serializer

Serializes the given record to string.

Specified by:

serializeToString in interface Serializer<Decimal>

Parameters:

record - The record to serialize.

Returns:

The serialized element.

deserializeFromString

public Decimal deserializeFromString(String s)

Description copied from interface: Serializer

De-serializes a record from string.

Specified by:

deserializeFromString in interface Serializer<Decimal>

Parameters:

s - The string to de-serialize.

Returns:

The deserialized element.

duplicate

public DecimalSerializer duplicate()

Description copied from interface: Serializer

Creates a deep copy of this serializer if it is necessary, i.e. if it is stateful. This can return itself if the serializer is not stateful.

We need this because Serializers might be used in several threads. Stateless serializers are inherently thread-safe while stateful serializers might not be thread-safe.

Specified by:

duplicate in interface Serializer<Decimal>

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
