Method Detail

read

public Short read(org.apache.flink.core.memory.DataInputView inputView,
                  byte typeByte)
           throws IOException

Description copied from interface: PropertyValueStrategy

Reads raw bytes from the given DataInputView and deserializes the contained object.

Parameters:

inputView - containing serialized object.

typeByte - byte needed to indicate whether serialized object has a variable length.

Returns:

deserialized object.

Throws:

IOException - when reading or deserialization of the object fails.

compare

public int compare(Short value,
                   Object other)

Description copied from interface: PropertyValueStrategy

Compares two objects.

Parameters:

value - first object.

other - second object.

Returns:

a negative integer, zero, or a positive integer as first object is less than, equal to, or greater than the second object.

is

public boolean is(Object value)

Description copied from interface: PropertyValueStrategy

Checks if given object is an instance of the data type the specific strategy handles.

Parameters:

value - to be checked.

Returns:

true if value is an instance of the data type this strategy handles. False otherwise.

getType

public Class<Short> getType()

Description copied from interface: PropertyValueStrategy

Gets the class of the data type the specific strategy handles.

Returns:

class of the type handled by this strategy.

get

public Short get(byte[] bytes)

Description copied from interface: PropertyValueStrategy

Deserializes an object from the provided byte array.

Parameters:

bytes - representing a serialized object.

Returns:

an instance of the type handled by this strategy.

getRawType

public byte getRawType()

Description copied from interface: PropertyValueStrategy

Gets a byte which represents the data type the specific strategy handles.

Returns:

a byte.

getRawBytes

public byte[] getRawBytes(Short value)

Description copied from interface: PropertyValueStrategy

Serializes the given object. The argument value can not be null.

Parameters:

value - the object to be serialized.

Returns:

byte array representation of the provided object.
