                            throws java.io.IOException

Description copied from class: DocValuesProducer

Returns NumericDocValues for this field. The returned instance need not be thread-safe: it will only be used by a single thread.

Specified by:

getNumeric in class DocValuesProducer

Throws:

java.io.IOException

getBinary

public BinaryDocValues getBinary(FieldInfo field)
                          throws java.io.IOException

Description copied from class: DocValuesProducer

Returns BinaryDocValues for this field. The returned instance need not be thread-safe: it will only be used by a single thread.

Specified by:

getBinary in class DocValuesProducer

Throws:

java.io.IOException

getSorted

public SortedDocValues getSorted(FieldInfo field)
                          throws java.io.IOException

Description copied from class: DocValuesProducer

Returns SortedDocValues for this field. The returned instance need not be thread-safe: it will only be used by a single thread.

Specified by:

getSorted in class DocValuesProducer

Throws:

java.io.IOException

getSortedNumeric

public SortedNumericDocValues getSortedNumeric(FieldInfo field)
                                        throws java.io.IOException

Description copied from class: DocValuesProducer

Returns SortedNumericDocValues for this field. The returned instance need not be thread-safe: it will only be used by a single thread.

Specified by:

getSortedNumeric in class DocValuesProducer

Throws:

java.io.IOException

getSortedSet

public SortedSetDocValues getSortedSet(FieldInfo field)
                                throws java.io.IOException

Description copied from class: DocValuesProducer

Returns SortedSetDocValues for this field. The returned instance need not be thread-safe: it will only be used by a single thread.

Specified by:

getSortedSet in class DocValuesProducer

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

java.io.IOException

ramBytesUsed

public long ramBytesUsed()

Description copied from interface: Accountable

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

getChildResources

public java.util.Collection<Accountable> getChildResources()

Description copied from interface: Accountable

Returns nested resources of this class. The result should be a point-in-time snapshot (to avoid race conditions).
