(¬ø) These strings appeared with dots between them to form the name in the source.

dimensions

public int dimensions

The number of matched brackets appearing after a single identifier; supports variable declarations.

Constructor Detail

Name

public Name(String n)

Takes a fully specified name (eg java.lang.String) as input.

Parameters:

n - A fully specified name.

Name

public Name(String n,
            int line,
            int byteOffset)

Takes a fully specified name (eg java.lang.String) as input.

Parameters:

n - A fully specified name.

Name

protected Name(String[] n)

Should only be called by the clone() method.

Parameters:

n - The value of the name variable.

Name

protected Name(String[] n,
               int line,
               int byteOffset)

Should only be called by the clone() method.

Parameters:

n - The value of the name variable.

Name

public Name(TokenValue token)

Parser's constructor.

Parameters:

token - The parser's token for the identifier.

Name

public Name(Name n,
            TokenValue token)

Parser's constructor.

Parameters:

n - A name that needs another identifier added to it.

token - The parser's token for the identifier.

Method Detail

length

public int length()

Returns the length of the name array.

Returns:

The length of the name array.

cutLast

public Name cutLast()

Returns a new Name object that is the same as this Name object, except the last identifier has been removed.

getVariableTypes

public HashSet getVariableTypes()

Returns a set of Arguments storing the name and type of each variable that is a subexpression of this expression. This method cannot be run before SemanticAnalysis runs.

Overrides:

getVariableTypes in class Expression

getVariableTypes

public HashSet getVariableTypes(boolean b)

Returns a set of Arguments storing the name and type of each variable that is a subexpression of this expression. This method cannot be run before SemanticAnalysis runs.

Parameters:

b - Flag set if this name is the name of an invoked method.

containsQuantifiedVariable

public boolean containsQuantifiedVariable()

Determines if there are any quantified variables in this expression. This method cannot be run before SemanticAnalysis runs.

Overrides:

containsQuantifiedVariable in class Expression

containsQuantifiedVariable

public boolean containsQuantifiedVariable(boolean b)

Determines if there are any quantified variables in this expression. This method cannot be run before SemanticAnalysis runs.

Parameters:

b - Flag set if this name is the name of an invoked method.

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.
