Enum DependencyType

java.lang.Object

java.lang.Enum<DependencyType>

tachyon.master.DependencyType

All Implemented Interfaces:

Serializable, Comparable<DependencyType>

public enum DependencyType
extends Enum<DependencyType>

The type of Dependency, Wide and Narrow. The difference is that how many input files does each output file require in the Dependency. In Narrow Dependency, each output file only requires one input file, while in Wide Dependency it requires more than one.

Enum Constant Detail

Wide

public static final DependencyType Wide

Wide Dependency means that each output file requires more than one input files.

Narrow

public static final DependencyType Narrow

Narrow Dependency means that each output file only requires one input file.

Method Detail

values

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

Returns:

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

valueOf

public static DependencyType 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

getDependencyType

public static DependencyType getDependencyType(int value)
                                        throws IOException

Get the enum value with the given integer value. It will check the legality.

Parameters:

value - The integer value, 1 or 2, means Wide or Narrow

Returns:

the enum value of DependencyType

Throws:

IOException

getValue

public int getValue()

Get the integer value of this enum value.
