Method Details

format

default java.lang.Object format(long value)

Format a long value. This is used by terms and histogram aggregations to format keys for fields that use longs as a doc value representation such as the long and date fields.

format

default java.lang.Object format(double value)

Format a double value. This is used by terms and stats aggregations to format keys for fields that use numbers as a doc value representation such as the long, double or date fields.

format

default java.lang.Object format(org.apache.lucene.util.BytesRef value)

Format a binary value. This is used by terms aggregations to format keys for fields that use binary doc value representations such as the keyword and ip fields.

parseLong

default long parseLong(java.lang.String value,
boolean roundUp,
java.util.function.LongSupplier now)

Parse a value that was formatted with format(long) back to the original long value.

parseDouble

default double parseDouble(java.lang.String value,
boolean roundUp,
java.util.function.LongSupplier now)

Parse a value that was formatted with format(double) back to the original double value.

parseBytesRef

default org.apache.lucene.util.BytesRef parseBytesRef(java.lang.String value)

Parse a value that was formatted with format(BytesRef) back to the original BytesRef.
