public abstract class List
extends ASTNode

Currently, this is just a wrapper class for LinkedList. The code that uses it looks a little cleaner when casts are all taken care of automatically.

Field Detail

list

protected LinkedList list

(¬ø) The list being wrapped.

separator

protected String separator

The characters appearing in between elements of the list in its string representation.

Constructor Detail

List

public List(int line,
            int byteOffset,
            String s)

Full constructor.

Parameters:

line - The line on which the source code represented by this node is found.

byteOffset - The byte offset from the beginning of the source file at which the source code represented by this node is found.

s - The list's element separator.

Method Detail

size

public int size()

Returns the size of the list.

Returns:

The number of elements currently in the list.

getSeparator

public String getSeparator()

Returns the separating characters.

Returns:

The value of separator.

sort

public void sort()

Sorts the list according to their natural ordering.

sort

public void sort(Comparator c)

Sorts the list according to the order induced by the specified comparator.

Parameters:

c - A comparator that determines the relative ordering of two elements in the list.

writeBuffer

protected void writeBuffer(StringBuffer buffer,
                           String separate)

Writes a string representation of this ASTNode to the specified buffer. The representation written is parsable by the LBJava compiler, but not very readable.

Parameters:

buffer - The buffer to write to.

write

public void write(StringBuffer buffer)

Writes a string representation of this ASTNode to the specified buffer. The representation written is parsable by the LBJava compiler, but not very readable.

Specified by:

write in class ASTNode

Parameters:

buffer - The buffer to write to.

equals

public boolean equals(Object o)

Determines whether this list is equivalent to another object.

Overrides:

equals in class Object

Parameters:

o - The other object.

Returns:

true iff this list is equivalent to o.

hashCode

public int hashCode()

A hash code based on the hash codes of the elements of the list.

Overrides:

hashCode in class Object
