Enum RuleType

java.lang.Object

java.lang.Enum<RuleType>

jtabwb.engine.RuleType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<RuleType>

public enum RuleType
extends java.lang.Enum<RuleType>

The type of a rule classify a rule applied during proof search. The type is determined by the interface implemented by a rule. We remark that this type is essentially redundant since the used value is completely determined by the interface implemented by a rule, it is useful to simplify the source code of the engine.

Method Detail

values

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

Returns:

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

valueOf

public static RuleType 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

getType

public static RuleType getType(_AbstractRule ruleToApply)

Returns the type of the specified rule.

Parameters:

ruleToApply - the rule.

Returns:

the type of the rule.
