Method Detail

builder

public static org.apache.kafka.connect.data.SchemaBuilder builder()

Returns a SchemaBuilder for a MicroDuration. The resulting schema will describe a field with the "io.debezium.time.MicroDuration" as the name and SchemaBuilder.float64() FLOAT64} for the literal type storing the number of microseconds for that duration.

You can use the resulting SchemaBuilder to set or override additional schema settings such as required/optional, default value, and documentation.

Returns:

the schema builder

schema

public static org.apache.kafka.connect.data.Schema schema()

Returns a Schema for a MicroDuration but with all other default Schema settings. The schema describes a field with the "io.debezium.time.MicroDuration" as the name and SchemaBuilder.float64() FLOAT64} for the literal type storing the number of microseconds.

Returns:

the schema

                                  int micros,
                                  Double daysPerMonthAvg)

Converts a number of time units to a duration in microseconds.

Parameters:

years - a number of years

months - a number of months

days - a number of days

hours - a number of hours

minutes - a number of minutes

seconds - a number of seconds

micros - a number of microseconds

daysPerMonthAvg - an optional value representing a days per month average; if null, the default duration from ChronoUnit.MONTHS is used.

Returns:

@return Approximate representation of the given interval as a number of microseconds

                                  int months,
                                  int days,
                                  int hours,
                                  int minutes,
                                  double seconds,
                                  Double daysPerMonthAvg)

Parameters:

years - a number of years

months - a number of months

days - a number of days

hours - a number of hours

minutes - a number of minutes

seconds - a number of seconds

daysPerMonthAvg - an optional value representing a days per month average; if null, the default duration from ChronoUnit.MONTHS is used.

Returns:
