Method Detail

values

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

Returns:

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

valueOf

public static NumberOperations.ClassInfo 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

getRank

public int getRank()

Gets the relative rank of this type in terms of numeric precision.

Returns:

int value for rank

getNumberClass

public Class<? extends Number> getNumberClass()

Gets the class that this type relates to

Returns:

the class

isIntegral

public boolean isIntegral()

Tests if this is an integral type

Returns:

true if integral; false otherwise

toString

public String toString()

Gets a String representation of this type

Overrides:

toString in class Enum<NumberOperations.ClassInfo>

Returns:

a String of the form "ClassInfo<classname>"

get

public static NumberOperations.ClassInfo get(Class<? extends Number> clazz)

Gets the ClassInfo type for the given class

Parameters:

clazz - a Number class

Returns:

the ClassInfo type or null if the class is not recognized
