Method Detail

values

public static ExprConstant.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 (ExprConstant.Op c : ExprConstant.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 ExprConstant.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 ExprConstant make(Pos pos,
                               int number)

Makes an ExprConstant node

Parameters:

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

number - - the number (this argument is ignored if op!=NUMBER)

make

public final ExprConstant make(Pos pos,
                               java.lang.String string)

Makes an ExprConstant node

Parameters:

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

string - - the string (this argument is ignored if op!=STRING)

toString

public final java.lang.String toString()

Returns the human readable label for this operator.

Overrides:

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