Method Detail

values

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

Returns:

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

valueOf

public static ScalarType 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

isInteger

public boolean isInteger()

Is this an integer (signed or unsigned). true if byte, short, int, long, ubyte, ushort, uint, or ulong.

Returns:

true if it is an integer type

isUInteger

public boolean isUInteger()

Is this an unsigned integer. true if ubyte, ushort, uint, or ulong.

Returns:

true if it is an unsigned integer type

isNumeric

public boolean isNumeric()

Is this a Java numeric type?

Returns:

true if the type is a Java numeric type. The numeric types are byte, short, int, long, float, and double.

isPrimitive

public boolean isPrimitive()

Is this a Java primitive type?

Returns:

true if the type is a Java primitive type. The numeric types and boolean are primitive types.

getScalarType

public static ScalarType getScalarType(String type)

Get the ScalarType for a string defining the type.

Parameters:

type - a character string defining the type

Returns:

the ScalarType or null if an illegal type

toString

public String toString()

Overrides:

toString in class Enum<ScalarType>
