Field Detail

object

public Expression object

(¬ø) The expression describing the object to be accessed.

name

public String name

(¬ø) The name of the field to be accessed.

Constructor Detail

FieldAccess

public FieldAccess(Expression o,
                   TokenValue n)

Parser's constructor. Line and byte offset information is taken from the name token.

Parameters:

o - The expression describing the object to be accessed.

n - Token representing the name of the field to be accessed.

FieldAccess

public FieldAccess(Expression o,
                   String n,
                   int line,
                   int byteOffset)

Full constructor.

Parameters:

o - The expression describing the object to be accessed.

n - The name of the field to be accessed.

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.

Method Detail

hashCode

public int hashCode()

Returns a hash code value for java hash structures.

Overrides:

hashCode in class Object

Returns:

A hash code for this object.

equals

public boolean equals(Object o)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class Object

Returns:

true iff this object is the same as the argument.

iterator

public ASTNodeIterator iterator()

Returns an iterator used to successively access the children of this node.

Specified by:

iterator in class ASTNode

Returns:

An iterator used to successively access the children of this node.

clone

public Object clone()

Creates a new object with the same primitive data, and recursively creates new member data objects as well.

Overrides:

clone in class ASTNode

Returns:

The clone node.

runPass

public void runPass(Pass pass)

Ensures that the correct run() method is called for this type of node.

Specified by:

runPass in class ASTNode

Parameters:

pass - The pass whose run() method should be called.

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.
