Field Detail

type

public Type type

(¬ø) The type to cast to.

expression

public Expression expression

(¬ø) The expression whose value should be casted.

Constructor Detail

CastExpression

public CastExpression(Type t,
                      Expression e)

Initializing constructor. Line and byte offset information are taken from the type's representation.

Parameters:

t - Reference to the object representing the cast's type.

e - Reference to the object representing the expression to cast.

Method Detail

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.

equals

public boolean equals(Object o)

Determines if this object is equivalent to another object.

Overrides:

equals in class Object

hashCode

public int hashCode()

A hash code based on the hash codes of type and expression.

Overrides:

hashCode in class Object

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.
