org.datavec.api.transform.StringReduceOp

All Implemented Interfaces:

Serializable, Comparable<StringReduceOp>

public enum StringReduceOp
extends Enum<StringReduceOp>

A string reduce op is used for combining strings such as merging, appending, or prepending. The following ops are supported: PREPEND: prepend the first string to the second APPEND: append the first string to the second MERGE: Merge the 2 strings FORMAT: Apply the format (the first column, to the string separated list via csv)

Method Detail

values

public static StringReduceOp[] 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 (StringReduceOp c : StringReduceOp.values())
    System.out.println(c);

Returns:

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

valueOf

public static StringReduceOp 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
