MemberEnter
public class MemberEnter extends JCTree.Visitor implements Completer(Code)
This is the second phase of Enter, in which classes are completed by entering their members into the class scope using MemberEnter.complete(). See Enter for an overview.

This is NOT part of any API supported by Sun Microsystems. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.

Field Detail
checkClash
final static boolean checkClash(Code)
A switch to determine whether we check for package/class conflicts



completionEnabled
boolean completionEnabled(Code)
A flag to disable completion from time to time during member enter, as we only need to look up types. This avoids unnecessarily deep recursion.



env
protected Env<AttrContext> env(Code)
Visitor argument: the current environment



halfcompleted
ListBuffer<Env<AttrContext>> halfcompleted(Code)
A queue for classes whose members still need to be entered into the symbol table.



isFirst
boolean isFirst(Code)
Set to true only when the first of a set of classes is processed from the halfcompleted queue.



memberEnterKey
final protected static Context.Key<MemberEnter> memberEnterKey(Code)




Constructor Detail
MemberEnter
protected MemberEnter(Context context)(Code)




Method Detail
DefaultConstructor
JCTree DefaultConstructor(TreeMaker make, ClassSymbol c, List<Type> typarams, List<Type> argtypes, List<Type> thrown, long flags, boolean based)(Code)
Generate default constructor for given class. For classes different from java.lang.Object, this is: c(argtype_0 x_0, ..., argtype_n x_n) throws thrown { super(x_0, ..., x_n) } or, if based == true: c(argtype_0 x_0, ..., argtype_n x_n) throws thrown { x_0.super(x_1, ..., x_n) }
Parameters:
  make - The tree factory.
Parameters:
  c - The class owning the default constructor.
Parameters:
  argtypes - The parameter types of the constructor.
Parameters:
  thrown - The thrown exceptions of the constructor.
Parameters:
  based - Is first parameter a this$n?



SuperCall
JCExpressionStatement SuperCall(TreeMaker make, List<Type> typarams, List<JCVariableDecl> params, boolean based)(Code)
Generate call to superclass constructor. This is: super(id_0, ..., id_n) or, if based == true id_0.super(id_1,...,id_n) where id_0, ..., id_n are the names of the given parameters.
Parameters:
  make - The tree factory
Parameters:
  params - The parameters that need to be passed to super
Parameters:
  typarams - The type parameters that need to be passed to super
Parameters:
  based - Is first parameter a this$n?



annotateDefaultValueLater
void annotateDefaultValueLater(JCExpression defaultValue, Env<AttrContext> localEnv, MethodSymbol m)(Code)
Queue processing of an attribute default value.



annotateLater
void annotateLater(List<JCAnnotation> annotations, Env<AttrContext> localEnv, Symbol s)(Code)
Queue annotations for later processing.



attribImportType
Type attribImportType(JCTree tree, Env<AttrContext> env)(Code)



complete
public void complete(Symbol sym) throws CompletionFailure(Code)
Complete entering a class.
Parameters:

getMethodEnv
public Env<AttrContext> getMethodEnv(JCMethodDecl tree, Env<AttrContext> env)(Code)



initEnv
Env<AttrContext> initEnv(JCVariableDecl tree, Env<AttrContext> env)(Code)
Create a fresh environment for a variable's initializer. If the variable is a field, the owner of the environment's scope is be the variable itself, otherwise the owner is the method enclosing the variable definition.
Parameters:
  tree - The variable definition.
Parameters:
  env - The environment current outside of the variable definition.



instance

memberEnter
void memberEnter(List<? extends JCTree> trees, Env<AttrContext> env)(Code)
Enter members from a list of trees.



methodEnv
Env<AttrContext> methodEnv(JCMethodDecl tree, Env<AttrContext> env)(Code)
Create a fresh environment for method bodies.
Parameters:
  tree - The method definition.
Parameters:
  env - The environment current outside of the method definition.



signature
Type signature(List<JCTypeParameter> typarams, List<JCVariableDecl> params, JCTree res, List<JCExpression> thrown, Env<AttrContext> env)(Code)
Construct method type from method signature.
Parameters:
  typarams - The method's type parameters.
Parameters:
  params - The method's value parameters.
Parameters:
  res - The method's result type,null if it is a constructor.
Parameters:
  thrown - The method's thrown exceptions.
Parameters:
  env - The method's (local) environment.
