Enum Constant Summary

FIFO
Forwards records in the order that they are read from each input source.

FirstAvailable
Reads one input source at a time, starting with the one that is first available

Fusion

Sort
Under the condition that the records arrive sorted by rank for each input source, the results will also be produced sorted by rank.

Method Summary

static OperationMode	valueOf(String name) Returns the enum constant of this type with the specified name.

Enum Constant Detail

FIFO

public static final OperationMode FIFO

Forwards records in the order that they are read from each input source. The output contains intermingled records from the input data sources

FirstAvailable

public static final OperationMode FirstAvailable

Reads one input source at a time, starting with the one that is first available

Sort

public static final OperationMode Sort

Under the condition that the records arrive sorted by rank for each input source, the results will also be produced sorted by rank. Note that this implies that the results will consist of intermingled records from all input sources, in the same manner as FIFO

Fusion

public static final OperationMode Fusion

Method Detail

values

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

Returns:

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

valueOf

public static OperationMode 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
