Method Details

add

void add(int doc,
 long value)

Specified by:

add in class DocValuesFieldUpdates

add

void add(int doc,
 BytesRef value)

Specified by:

add in class DocValuesFieldUpdates

reset

void reset(int doc)

Description copied from class: DocValuesFieldUpdates

Adds an update that resets the documents value.

Overrides:

reset in class DocValuesFieldUpdates

Parameters:

doc - the doc to update

add

void add(int docId,
 DocValuesFieldUpdates.Iterator iterator)

Description copied from class: DocValuesFieldUpdates

Adds the value for the given docID. This method prevents conditional calls to DocValuesFieldUpdates.Iterator.longValue() or DocValuesFieldUpdates.Iterator.binaryValue() since the implementation knows if it's a long value iterator or binary value

Specified by:

add in class DocValuesFieldUpdates

binaryValue

protected abstract BytesRef binaryValue()

longValue

protected abstract long longValue()

any

boolean any()

Description copied from class: DocValuesFieldUpdates

Returns true if this instance contains any updates.

Overrides:

any in class DocValuesFieldUpdates

ramBytesUsed

public long ramBytesUsed()

Description copied from interface: Accountable

Return the memory usage of this object in bytes. Negative values are illegal.

Specified by:

ramBytesUsed in interface Accountable

Overrides:

ramBytesUsed in class DocValuesFieldUpdates

iterator

DocValuesFieldUpdates.Iterator iterator()

Description copied from class: DocValuesFieldUpdates

Returns an DocValuesFieldUpdates.Iterator over the updated documents and their values.

Specified by:

iterator in class DocValuesFieldUpdates
