Method Detail

clone

public java.lang.Object clone()

Description copied from class: SymtabEntry

This is a shallow copy clone

Overrides:

clone in class InterfaceEntry

generate

public void generate(java.util.Hashtable symbolTable,
                     java.io.PrintWriter stream)

Invoke the interface generator.

Overrides:

generate in class InterfaceEntry

Parameters:

symbolTable - The symbol table is a hash table whose key is a fully qualified type name and whose value is a SymtabEntry or a subclass of SymtabEntry.

stream - The stream to which the generator should sent its output.

See Also:

SymtabEntry

generator

public Generator generator()

Access the value generator.

Overrides:

generator in class InterfaceEntry

Returns:

an object which implements the ValueGen interface.

See Also:

ValueGen

addSupport

public void addSupport(SymtabEntry supports)

Add an InterfaceEntry to the list of interfaces which this value supports. During parsing, the parameter to this method COULD be a ForwardEntry, but when parsing is complete, calling supports will return a vector which only contains InterfaceEntry's.

Parameters:

supports - a ForwardEntry or InterfaceEntry

supports

public java.util.Vector<SymtabEntry> supports()

This method returns a vector of InterfaceEntrys.

Returns:

a Vector of InterfaceEntry

addSupportName

public void addSupportName(java.lang.String name)

Add to the list of support names.

Parameters:

name - name to add

supportsNames

public java.util.Vector<java.lang.String> supportsNames()

This method returns a vector of Strings, each of which is a fully qualified name of an interface. This vector corresponds to the supports vector. The first element of this vector is the name of the first element of the supports vector, etc.

Returns:

a Vector of Strings

derivedFromAddElement

void derivedFromAddElement(SymtabEntry e,
                           boolean isSafe,
                           Scanner scanner)

Add a parent value type to the list of parent types for the value. This method:

• Allows only the first added class to be concrete if the receiver is concrete.
• Does not allow any added classes to be concrete if the receiver is abstract.
• Does not allow duplicate classes to be added.

derivedFromAddElement

void derivedFromAddElement(SymtabEntry e,
                           Scanner scanner)

Overrides:

derivedFromAddElement in class InterfaceEntry

replaceForwardDecl

public boolean replaceForwardDecl(ForwardEntry oldEntry,
                                  InterfaceEntry newEntry)

Overrides:

replaceForwardDecl in class InterfaceEntry

initializersAddElement

void initializersAddElement(MethodEntry method,
                            Scanner scanner)

initializers

public java.util.Vector<MethodEntry> initializers()

tagMethods

public void tagMethods()

Tag all methods introduced by the value type as 'value methods' so they can be differentiated in the emitters from any interface methods that the value type supports.

isCustom

public boolean isCustom()

Get the 'custom' marshaling property.

Returns:

if the entry should be marshaled customly

setCustom

public void setCustom(boolean isCustom)

Set the 'custom' marshaling property.

Parameters:

isCustom - if the entry should be marshaled customly

isSafe

public boolean isSafe()

Return whether or not the value type can be "safely" truncated to its concrete parent type.

Returns:

true if it can be safely truncated
