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

Reads 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

Throws:

IOException

write

public void write(DataOutput out)
           throws IOException

Description copied from interface: Writable

Writes the fields of this object to out.

Specified by:

write in interface Writable

Throws:

IOException

equals

public boolean equals(Object o)

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

hashCode

public int hashCode()

compareTo

public int compareTo(Object o)

Compares two FloatWritables.

Specified by:

compareTo in interface Comparable

toString

public String toString()
