Enum Constant Detail

LE

public static final RelationType LE

LT

public static final RelationType LT

GE

public static final RelationType GE

GT

public static final RelationType GT

EQ

public static final RelationType EQ

NE

public static final RelationType NE

IS

public static final RelationType IS

Value on the left belongs to the class of values defined on the right. Currently used to represent: - instanceof (DfaValue IS DfaTypeValue) - optional presense (DfaValue IS DfaOptionalValue)

IS_NOT

public static final RelationType IS_NOT

Value on the left does not belong to the class of values defined on the right (opposite to IS).

Method Detail

values

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

Returns:

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

valueOf

public static RelationType 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

isSubRelation

public boolean isSubRelation(RelationType other)

getNegated

public RelationType getNegated()

getFlipped

public RelationType getFlipped()

isInequality

public boolean isInequality()

Returns:

true if this relation is >, >=, <, != or <=

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<RelationType>

fromElementType

public static RelationType fromElementType(IElementType type)

equivalence

public static RelationType equivalence(boolean equal)
