Field Detail

isArrow

public final boolean isArrow

True if and only if this operator is the Cartesian product "->", a "seq" multiplicity, or is a multiplicity arrow of the form "?->?".

Method Detail

values

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

Returns:

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

valueOf

public static ExprBinary.Op 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

make

public final Expr make(Pos pos,
                       Pos closingBracket,
                       Expr left,
                       Expr right)

Constructs a new ExprBinary node.

Parameters:

pos - - the original position in the source file (can be null if unknown)

left - - the left hand side expression

right - - the right hand side expression

toString

public final java.lang.String toString()

Returns the human readable label for this operator.

Overrides:

toString in class java.lang.Enum<ExprBinary.Op>

toHTML

public final java.lang.String toHTML()

Returns the human readable label already encoded for HTML
