Method Detail

values

public static MapTypeOps[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (MapTypeOps c : MapTypeOps.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static MapTypeOps valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getTypeClass

public Class<org.apache.hadoop.io.MapWritable> getTypeClass()

Description copied from interface: TypeOps

Class object for generic type T.

Specified by:

getTypeClass in interface TypeOps<org.apache.hadoop.io.MapWritable>

Returns:

Class<T> object

create

public org.apache.hadoop.io.MapWritable create()

Description copied from interface: TypeOps

Create new instance of type T.

Specified by:

create in interface TypeOps<org.apache.hadoop.io.MapWritable>

Returns:

createCopy

public org.apache.hadoop.io.MapWritable createCopy(org.apache.hadoop.io.MapWritable from)

Description copied from interface: TypeOps

Create a copy of passed object

Specified by:

createCopy in interface TypeOps<org.apache.hadoop.io.MapWritable>

Parameters:

from - Object to copy

Returns:

Copy

set

public void set(org.apache.hadoop.io.MapWritable to,
                org.apache.hadoop.io.MapWritable from)

Description copied from interface: TypeOps

Copies the value from the second argument into the first.

Specified by:

set in interface TypeOps<org.apache.hadoop.io.MapWritable>

Parameters:

to - Object into which the value should be copied

from - Value of object to be copied
