dataType

private final TensorDataType dataType

Constructor Detail

TensorFieldValue

public TensorFieldValue(com.yahoo.tensor.TensorType type)

Create an empty tensor field value

TensorFieldValue

public TensorFieldValue(com.yahoo.tensor.Tensor tensor)

Create a tensor field value containing the given tensor

Method Detail

getTensor

public Optional<com.yahoo.tensor.Tensor> getTensor()

getDataType

public TensorDataType getDataType()

Specified by:

getDataType in class FieldValue

printXml

public void printXml(XmlStream xml)

Specified by:

printXml in class FieldValue

clear

public void clear()

Specified by:

clear in class FieldValue

assign

public void assign(Object o)

Description copied from class: FieldValue

Assign this non-fieldvalue value to this field value. This is used to be able to assign ints to Integer field values and List to Array field values and such.

Override to accept the specific types that should be legal.

Specified by:

assign in class FieldValue

assignTensor

public void assignTensor(Optional<com.yahoo.tensor.Tensor> tensor)

serialize

public void serialize(Field field,
                      FieldWriter writer)

Description copied from class: FieldValue

Write out field value to the specified writer

Specified by:

serialize in class FieldValue

deserialize

public void deserialize(Field field,
                        FieldReader reader)

Description copied from class: FieldValue

Read a field value from the specified reader

Specified by:

deserialize in class FieldValue

equals

public boolean equals(Object o)

Overrides:

equals in class com.yahoo.vespa.objects.Identifiable

getWrappedValue

public Object getWrappedValue()

Description copied from class: FieldValue

Used to retrieve wrapped type for simple types, such that you can use get methods to retrieve ints and floats directly instead of Int/Float field values. Complex types that can't be specified by simple java types just return themself.

Overrides:

getWrappedValue in class FieldValue
