Enum Constant Detail

LONG

public static final SVal LONG

The value is a long integer. SPARK does not bother with shorter forms of integer values.

DOUBLE

public static final SVal DOUBLE

The value is a double precision floating point number. SPARK does not bother with shorter forms of floating point.

BOOLEAN

public static final SVal BOOLEAN

The value is boolean, true/false

STRING

public static final SVal STRING

The value is a string

OBJECT

public static final SVal OBJECT

The value is an SO object

ARRAY

public static final SVal ARRAY

The value is an SA array object.

SVVAL

public static final SVal SVVAL

This is used for fields that can hold an SV. This is never used as the content of an SV.

NULL

public static final SVal NULL

There is no value

Method Detail

values

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

Returns:

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

valueOf

public static SVal 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
