BooleanWritable

public BooleanWritable(boolean value)

方法详细资料

set

public void set(boolean value)

Set the value of the BooleanWritable

get

public boolean get()

Returns the value of the BooleanWritable

readFields

public void readFields(DataInput in)
                throws IOException

从接口复制的说明: Writable

Deserialize the fields of this object from in.

For efficiency, implementations should attempt to re-use storage in the existing object where possible.

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

equals

public boolean equals(Object o)

覆盖:

equals 在类中 Object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object

compareTo

public int compareTo(Object o)

指定者:

compareTo 在接口中 Comparable

toString

public String toString()

覆盖:

toString 在类中 Object
