type

public Type type

(¬ø) The type of the declared variable.

Constructor Detail

VariableDeclaration

public VariableDeclaration(Name n)

Parser's constructor, leaving the type to be filled in later.

Parameters:

n - The name of the declared variable.

VariableDeclaration

public VariableDeclaration(Name n,
                           Expression i)

Parser's constructor, leaving the type to be filled in later.

Parameters:

n - The name of the declared variable.

i - The initializing expression for the declared variable.

VariableDeclaration

public VariableDeclaration(Type t,
                           NameList n,
                           ExpressionList i,
                           boolean f)

Full constructor.

Parameters:

t - The type of the declared variables.

n - The names of the declared variables.

i - The initializing expressions for the declared variables.

f - Whether or not the variables were declared as final.

Method Detail

addVariables

public void addVariables(VariableDeclaration v)

Adds the declarations in the specified declaration statement to the declarations in this statement.

Parameters:

v - The variables to be added.

setType

public void setType(Type t)

Setting this declaration statement's type also sets its line and byte offset information.

Parameters:

t - The new type for this variable declaration statement.

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.
