Method Detail

values

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

Returns:

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

valueOf

public static InstructionPrinter.InstructionLineColumn 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

printLabel

public void printLabel(LogStream out)

Prints this column's label to a given stream after padding the stream with '_' characters until its position is equal to this column's position.

Parameters:

out - the print stream

advance

public void advance(LogStream out)

Prints space characters to a given stream until its position is equal to this column's position.

Parameters:

out - the print stream
