Enum ZUtils.ZExprKind

java.lang.Object

java.lang.Enum<ZUtils.ZExprKind>

net.sourceforge.czt.z.util.ZUtils.ZExprKind

All Implemented Interfaces:

Serializable, Comparable<ZUtils.ZExprKind>

Enclosing class:

ZUtils

public static enum ZUtils.ZExprKind
extends Enum<ZUtils.ZExprKind>

Enumerated type used to distinguish what kind of Z Expr is. It is useful for determining statically, without type information, the kind of term being handled. For instance, DefTable uses this to best guess the kind of OmitBox involved in a declaration.

Method Detail

values

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

Returns:

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

valueOf

public static ZUtils.ZExprKind 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
