java.lang.Object
java.lang.Enum<HdfsConstants.NodeType>
org.apache.hadoop.hdfs.server.common.HdfsConstants.NodeType
- All Implemented Interfaces:
- Serializable, Comparable<HdfsConstants.NodeType>
- Enclosing interface:
- HdfsConstants
public static enum HdfsConstants.NodeType
- extends Enum<HdfsConstants.NodeType>
Type of the node
NAME_NODE
public static final HdfsConstants.NodeType NAME_NODE
DATA_NODE
public static final HdfsConstants.NodeType DATA_NODE
values
public static HdfsConstants.NodeType[] 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 (HdfsConstants.NodeType c : HdfsConstants.NodeType.values())
System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in
the order they are declared
valueOf
public static HdfsConstants.NodeType 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
