方法详细资料

set

public void set(int left,
       int right)

Set the left and right values.

getFirst

public int getFirst()

getSecond

public int getSecond()

readFields

public void readFields(DataInput in)
                throws IOException

Read the two integers. Encoded as: MIN_VALUE -> 0, 0 -> -MIN_VALUE, MAX_VALUE-> -1

指定者:

readFields 在接口中 Writable

参数:

in - DataInput to deseriablize this object from.

抛出:

IOException

write

public void write(DataOutput out)
           throws IOException

从接口复制的说明: Writable

Serialize the fields of this object to out.

指定者:

write 在接口中 Writable

参数:

out - DataOuput to serialize this object into.

抛出:

IOException

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object

equals

public boolean equals(Object right)

覆盖:

equals 在类中 Object

compareTo

public int compareTo(SecondarySort.IntPair o)

指定者:

compareTo 在接口中 Comparable<SecondarySort.IntPair>
