Interface MJTopLevelDeclaration

All Known Implementing Classes:

MJTopLevelMethodDeclaration

public interface MJTopLevelDeclaration

This interface is implemented by all classes that represent top-level declarations in MultiJava, i.e., all open-class declarations.

Method Summary
void	accept(MjcVisitor p)           Accepts the specified visitor
CMember	checkInterface(CContextType context)           Checks the basic interfaces to make sure things generally look OK.
CType	getOpenClassType()           Returns the type that this open member extends
boolean	isExternal()           Indicates whether this member is external.

 

Method Detail

accept

public void accept(MjcVisitor p)

Accepts the specified visitor

Parameters:

p - the visitor

getOpenClassType

public CType getOpenClassType()

Returns the type that this open member extends

Returns:

a class representing the type extended by this open member

isExternal

public boolean isExternal()

Indicates whether this member is external.

Returns:

a flag indicating whether this member is external

checkInterface

public CMember checkInterface(CContextType context)
                                throws PositionedError

Checks the basic interfaces to make sure things generally look OK. This pass gathers information about the type signatures of everything (imported class files, classes being compiled, methods, fields, etc...) needed for the later passes. This information is stored in a context hierarchy that is bound to the AST.

Returns:

a representation of the member iff no errors are detected

Throws:

PositionedError - if any checks fail
