Constructor Detail

MethodInvocation

public MethodInvocation(Name n)

Initializing constructor. Line and byte offset information is taken from the representation of the name.

Parameters:

n - The name of the method being invoked.

MethodInvocation

public MethodInvocation(Name n,
                        ExpressionList a)

Initializing constructor. Line and byte offset information is taken from the representation of the name.

Parameters:

n - The name of the method being invoked.

a - The argument expressions passed to the method.

MethodInvocation

public MethodInvocation(Expression p,
                        TokenValue n)

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

Parameters:

p - Represents the object whose method is being invoked.

n - Token representing the name of the method being invoked.

MethodInvocation

public MethodInvocation(Expression p,
                        TokenValue n,
                        ExpressionList a)

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

Parameters:

p - Represents the object whose method is being invoked.

n - Token representing the name of the method being invoked.

a - The argument expressions passed to the method.

MethodInvocation

public MethodInvocation(Expression p,
                        Name n,
                        ExpressionList a,
                        int line,
                        int byteOffset)

Full constructor.

Parameters:

p - Represents the object whose method is being invoked.

n - The name of the method being invoked.

a - The argument expressions passed to the method.

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

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

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

senseValueChild

public void senseValueChild()

Sets the isSensedValue flag.

Overrides:

senseValueChild in class Expression

See Also:

SemanticAnalysis

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.
