com.espertech.esper.epl.spec.OutputLimitLimitType

All Implemented Interfaces:

Serializable, Comparable<OutputLimitLimitType>

public enum OutputLimitLimitType
extends Enum<OutputLimitLimitType>

Enum for describing the type of output limit within an interval.

Enum Constant Summary

Enum Constants

Enum Constant and Description
ALL The ALL keyword has been explicitly specified: Output all events, relative to the output batch.
DEFAULT The ALL keyword has not been explicitly specified: Output all events, relative to the output batch.
FIRST Output first event, relative to the output batch.
LAST Output last event, relative to the output batch.
SNAPSHOT Output a snapshot of the current state, relative to the full historical state of a statement.

Method Summary

Modifier and Type	Method and Description
static OutputLimitLimitType	valueOf(String name) Returns the enum constant of this type with the specified name.
static OutputLimitLimitType[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

FIRST

public static final OutputLimitLimitType FIRST

Output first event, relative to the output batch.

LAST

public static final OutputLimitLimitType LAST

Output last event, relative to the output batch.

ALL

public static final OutputLimitLimitType ALL

The ALL keyword has been explicitly specified: Output all events, relative to the output batch.

In the fully-grouped and aggregated case, the explicit ALL outputs one row for each group.

DEFAULT

public static final OutputLimitLimitType DEFAULT

The ALL keyword has not been explicitly specified: Output all events, relative to the output batch.

In the fully-grouped and aggregated case, the default ALL outputs all events of the batch row-by-row, multiple per group.

SNAPSHOT

public static final OutputLimitLimitType SNAPSHOT

Output a snapshot of the current state, relative to the full historical state of a statement.

Method Detail

values

public static OutputLimitLimitType[] 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 (OutputLimitLimitType c : OutputLimitLimitType.values())
    System.out.println(c);

Returns:

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

valueOf

public static OutputLimitLimitType valueOf(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:

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

NullPointerException - if the argument is null
