FloatWritable

public FloatWritable()

FloatWritable

public FloatWritable(float value)
Method Detail

set

public void set(float value)
Set the value of this FloatWritable.


get

public float get()
Return the value of this FloatWritable.


readFields

public void readFields(DataInput in)
                throws IOException
Description copied from interface: Writable
Deserialize the fields of this object from in.

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

Specified by:
readFields in interface Writable
Parameters:
in - DataInput to deseriablize this object from.
Throws:
IOException

write

public void write(DataOutput out)
           throws IOException
Description copied from interface: Writable
Serialize the fields of this object to out.

Specified by:
write in interface Writable
Parameters:
out - DataOuput to serialize this object into.
Throws:
IOException

equals

public boolean equals(Object o)
Returns true iff o is a FloatWritable with the same value.

Overrides:
equals in class Object

hashCode

public int hashCode()
Overrides:
hashCode in class Object

compareTo

public int compareTo(FloatWritable o)
Compares two FloatWritables.

Specified by:
compareTo in interface Comparable<FloatWritable>

toString

public String toString()
Overrides:
toString in class Object
