               throws IOException

Throws:

IOException

Method Details

getMergeInstance

public NormsProducer getMergeInstance()

Description copied from class: NormsProducer

Returns an instance optimized for merging. This instance may only be used from the thread that acquires it.

The default implementation returns this

Overrides:

getMergeInstance in class NormsProducer

readFields

private void readFields(IndexInput meta,
 FieldInfos infos)
                 throws IOException

Throws:

IOException

getDataInput

private RandomAccessInput getDataInput(FieldInfo field,
 Lucene80NormsProducer.NormsEntry entry)
                                throws IOException

Throws:

IOException

getDisiInput

private IndexInput getDisiInput(FieldInfo field,
 Lucene80NormsProducer.NormsEntry entry)
                         throws IOException

Throws:

getDisiJumpTable

private RandomAccessInput getDisiJumpTable(FieldInfo field,
 Lucene80NormsProducer.NormsEntry entry)
                                    throws IOException

Throws:

IOException

getNorms

public NumericDocValues getNorms(FieldInfo field)
                          throws IOException

Description copied from class: NormsProducer

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

Specified by:

getNorms in class NormsProducer

Throws:

IOException

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Throws:

IOException

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

checkIntegrity

public void checkIntegrity()
                    throws IOException

Description copied from class: NormsProducer

Checks consistency of this producer

Note that this may be costly in terms of I/O, e.g. may involve computing a checksum value against large data files.

Specified by:

checkIntegrity in class NormsProducer

Throws:

IOException

toString

public String toString()

Overrides:

toString in class Object
