Enum Constant Detail

UNKNOWN

public static final TraversingStructureEnum UNKNOWN

ROWWISE

public static final TraversingStructureEnum ROWWISE

Backing vectors are directly available as row views.

COLWISE

public static final TraversingStructureEnum COLWISE

Column vectors are directly available as column views.

SPARSEROWWISE

public static final TraversingStructureEnum SPARSEROWWISE

Only some row-wise vectors are really present (can use iterateNonEmpty). Corresponds to [[org.apache.mahout.math.SparseMatrix]].

Method Detail

values

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

Returns:

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

valueOf

public static TraversingStructureEnum 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
