FloatWritable

public FloatWritable()

FloatWritable

public FloatWritable(float value)

Method Detail

set

public void set(float value)

Set the value of this FloatWritable.

Parameters:

value - value.

get

public float get()

Return the value of this FloatWritable.

Returns:

value.

readFields

public void readFields(java.io.DataInput in)
                throws java.io.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:

java.io.IOException - any other problem for readFields.

write

public void write(java.io.DataOutput out)
           throws java.io.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:

java.io.IOException - any other problem for write.

equals

public boolean equals(java.lang.Object o)

Returns true iff o is a FloatWritable with the same value.

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

compareTo

public int compareTo(FloatWritable o)

Compares two FloatWritables.

Specified by:

compareTo in interface java.lang.Comparable<FloatWritable>

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
