Enum Constant Detail

NONE

public static final CastMode NONE

No cast needed.

CAST

public static final CastMode CAST

Cast an address to the specified type.

REAL

public static final CastMode REAL

Return the real value part.

IMAGINARY

public static final CastMode IMAGINARY

Return the imaginary part. Returns 0 for everything except a complex value.

FLOOR

public static final CastMode FLOOR

Return the next lower integer value. This is the same computation as the Fortran AINT() function.

CEILING

public static final CastMode CEILING

Return the next higher integer value.

ROUND

public static final CastMode ROUND

Return the nearest integer value. This is the same computation as the Fortran ANINT() function.

TRUNCATE

public static final CastMode TRUNCATE

Return the integer part of the value.

INVALID

public static final CastMode INVALID

No valid cast.

Method Detail

values

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

Returns:

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

valueOf

public static CastMode valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<CastMode>
