Field Detail

executableSet

protected static final EnumSet<LogicalNodeStatus> executableSet

The EnumSet of executable states.

executingSet

protected static final EnumSet<LogicalNodeStatus> executingSet

The EnumSet of executing states.

finishedSet

protected static final EnumSet<LogicalNodeStatus> finishedSet

The EnumSet of finished states.

mergeableSet

protected static final EnumSet<LogicalNodeStatus> mergeableSet

Method Detail

values

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

Returns:

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

valueOf

public static LogicalNodeStatus 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

isExecutable

public boolean isExecutable()

Gets whether the computation is eligible for execution.

isExecuting

public boolean isExecuting()

Gets whether the computation is executing.

isFinished

public boolean isFinished()

Gets whether the computation is finished.

isMergeable

public boolean isMergeable()

Gets whether the computation can be merged with another for the purposes of subflow embedding.
