Enum Constant Detail

COUNT_BASED

public static final SlidingWindowType COUNT_BASED

The definition of count-based sliding window from "Sliding Sketches: A Framework using Time Zones for Data * Stream Processing in Sliding Windows" by Gou et al.: Given a data stream S, a count-based sliding window with length N means the union of the last N items.

TIME_BASED

public static final SlidingWindowType TIME_BASED

The definition of time-based sliding window from "Sliding Sketches: A Framework using Time Zones for Data Stream Processing in Sliding Windows" by Gou et al.: Given a data stream S, a time-based sliding window with length N means the union of data items which arrive in the last N time units.

NONE

public static final SlidingWindowType NONE

NONE indicates that sliding window model is not used.

Method Detail

values

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

Returns:

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

valueOf

public static SlidingWindowType 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
