Method Detail

getFactory

public static PrimitiveDataType.Factory getFactory()

clone

public ByteFieldValue clone()

Overrides:

clone in class FieldValue

getNumber

public java.lang.Number getNumber()

Specified by:

getNumber in class NumericFieldValue

clear

public void clear()

Specified by:

clear in class FieldValue

assign

public void assign(java.lang.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

getByte

public byte getByte()

getWrappedValue

public java.lang.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

getDataType

public DataType getDataType()

Specified by:

getDataType in class FieldValue

printXml

public void printXml(XmlStream xml)

Specified by:

printXml in class FieldValue

toString

public java.lang.String toString()

Overrides:

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

hashCode

public int hashCode()

Overrides:

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

equals

public boolean equals(java.lang.Object o)

Overrides:

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

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

compareTo

public int compareTo(FieldValue fieldValue)

Specified by:

compareTo in interface java.lang.Comparable<FieldValue>

Overrides:

compareTo in class FieldValue
