java.lang.Enum<AggregationStep>

org.apache.iotdb.db.mpp.plan.planner.plan.parameter.AggregationStep

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<AggregationStep>

public enum AggregationStep
extends java.lang.Enum<AggregationStep>

This attribute indicates the input and output type of the Aggregator.

There are three types of input/output:

• Raw: raw data, as input only
• Partial: intermediate aggregation result
• Final: final aggregation result

Method Detail

values

public static AggregationStep[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (AggregationStep c : AggregationStep.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static AggregationStep valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
