Constructor Detail

IfStatement

public IfStatement(Expression c,
                   Statement t,
                   int line,
                   int byteOffset)

Initializing constructor.

Parameters:

c - The condition controlling execution.

t - The statement to execute if the condition is true.

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.

IfStatement

public IfStatement(Expression c,
                   Statement t,
                   Statement e,
                   int line,
                   int byteOffset)

Full constructor.

Parameters:

c - The condition controlling execution.

t - The statement to execute if the condition is true.

e - The statement to execute if the condition is false, if any.

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

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.

hashCode

public int hashCode()

Returns a hash code for this ASTNode.

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Distinguishes this ASTNode from other objects according to its contents recursively.

Overrides:

equals in class Object

Parameters:

o - Another object.

Returns:

true iff this node is equal to o.

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.
