FieldStats

protected FieldStats(int type,
                     long maxDoc,
                     long docCount,
                     long sumDocFreq,

メソッドの詳細

getMaxDoc

public long getMaxDoc()

戻り値:

the total number of documents. Note that, documents marked as deleted that haven't yet been merged way aren't taken into account.

getDocCount

public long getDocCount()

戻り値:

the number of documents that have at least one term for this field, or -1 if this measurement isn't available. Note that, documents marked as deleted that haven't yet been merged way aren't taken into account.

getDensity

public int getDensity()

戻り値:

The percentage of documents that have at least one value for this field. This is a derived statistic and is based on: 'doc_count / max_doc'

getSumDocFreq

public long getSumDocFreq()

戻り値:

the sum of each term's document frequency in this field, or -1 if this measurement isn't available. Document frequency is the number of documents containing a particular term. Note that, documents marked as deleted that haven't yet been merged way aren't taken into account.

getSumTotalTermFreq

public long getSumTotalTermFreq()

戻り値:

the sum of the term frequencies of all terms in this field across all documents, or -1 if this measurement isn't available. Term frequency is the total number of occurrences of a term in a particular document and field. Note that, documents marked as deleted that haven't yet been merged way aren't taken into account.

getMinValue

public T getMinValue()

戻り値:

the lowest value in the field. Note that, documents marked as deleted that haven't yet been merged way aren't taken into account.

getMaxValue

public T getMaxValue()

戻り値:

the highest value in the field. Note that, documents marked as deleted that haven't yet been merged way aren't taken into account.

getMinValueAsString

public abstract String getMinValueAsString()

戻り値:

the lowest value in the field represented as a string. Note that, documents marked as deleted that haven't yet been merged way aren't taken into account.

getMaxValueAsString

public abstract String getMaxValueAsString()

戻り値:

the highest value in the field represented as a string. Note that, documents marked as deleted that haven't yet been merged way aren't taken into account.

valueOf

protected abstract T valueOf(String value,
                             String optionalFormat)

パラメータ:

value - The string to be parsed

optionalFormat - A string describing how to parse the specified value. Whether this parameter is supported depends on the implementation. If optionalFormat is specified and the implementation doesn't support it an UnsupportedOperationException is thrown

append

public void append(FieldStats stats)

Merges the provided stats into this stats instance.

match

public boolean match(IndexConstraint constraint)

戻り値:

true if this instance matches with the provided index constraint, otherwise false is returned

public XContentBuilder toXContent(XContentBuilder builder,
                                  ToXContent.Params params)

              throws IOException

定義:

readFrom インタフェース内 Streamable

例外:

IOException

writeTo

public void writeTo(StreamOutput out)
             throws IOException

定義:

writeTo インタフェース内 Streamable
