Class ScriptDocValues<T>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractList<T>

org.elasticsearch.index.fielddata.ScriptDocValues<T>

All Implemented Interfaces:

Iterable<T>, Collection<T>, List<T>, FieldValues<T>

Direct Known Subclasses:

IpFieldMapper.IpFieldType.IpScriptDocValues, ScriptDocValues.Booleans, ScriptDocValues.BytesRefs, ScriptDocValues.Dates, ScriptDocValues.Doubles, ScriptDocValues.Geometry, ScriptDocValues.Longs, ScriptDocValues.Strings

public abstract class ScriptDocValues<T>
extends AbstractList<T>
implements FieldValues<T>

Script level doc values, the assumption is that any implementation will implement a getValue method. Implementations should not internally re-use objects for the values that they return as a single ScriptDocValues instance can be reused to return values form multiple documents.

setNextDocId

public abstract void setNextDocId(int docId)
                           throws IOException

Set the current doc ID.

Throws:

IOException

add

public final void add(int index,
 T element)

Specified by:

add in interface List<T>

Overrides:

add in class AbstractList<T>

remove

public final boolean remove(Object o)

Specified by:

remove in interface Collection<T>

Specified by:

remove in interface List<T>

Overrides:

remove in class AbstractCollection<T>

replaceAll

public final void replaceAll(UnaryOperator<T> operator)

Specified by:

getValues

public List<T> getValues()

Description copied from interface: FieldValues

All underlying values. Note this boxes primitives

Specified by:

getValues in interface FieldValues<T>

getNonPrimitiveValue

public T getNonPrimitiveValue()

Description copied from interface: FieldValues

The first value as a subclass of Object. Boxes primitives

Specified by:

getNonPrimitiveValue in interface FieldValues<T>

getLongValue

public long getLongValue()

Description copied from interface: FieldValues

The first value as a primitive long. For performance reasons, implementations should avoid intermediate boxings if possible

Specified by:

getDoubleValue

public double getDoubleValue()

Description copied from interface: FieldValues

The first value as a primitive double. For performance reasons, implementations should avoid intermediate boxings if possible

Specified by:

getDoubleValue in interface FieldValues<T>

throwIfEmpty

protected void throwIfEmpty()
