Enum KeyValueHeap.SeekType
java.lang.Object
java.lang.Enum<KeyValueHeap.SeekType>
org.apache.hadoop.hbase.regionserver.KeyValueHeap.SeekType
- All Implemented Interfaces:
- Serializable, Comparable<KeyValueHeap.SeekType>
- Enclosing class:
- KeyValueHeap
public static enum KeyValueHeap.SeekType
- extends Enum<KeyValueHeap.SeekType>
A helper enum that knows how to call the correct seek function within a
KeyValueScanner
.
NORMAL
public static final KeyValueHeap.SeekType NORMAL
EXACT
public static final KeyValueHeap.SeekType EXACT
values
public static KeyValueHeap.SeekType[] 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 (KeyValueHeap.SeekType c : KeyValueHeap.SeekType.values())
System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in
the order they are declared
valueOf
public static KeyValueHeap.SeekType 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
seek
public abstract boolean seek(KeyValueScanner scanner,
KeyValue kv,
boolean forward)
throws IOException
- Throws:
IOException
