 IDLID clone)

Method Details

clone

public Object clone()

Description copied from class: SymtabEntry

This is a shallow copy clone

Overrides:

clone in class SymtabEntry

generate

public void generate(Hashtable symbolTable,
 PrintWriter stream)

Invoke the union generator.

Overrides:

generate in class SymtabEntry

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 union generator.

Overrides:

generator in class SymtabEntry

Returns:

an object which implements the UnionGen interface.

• UnionGen

addBranch

void addBranch(UnionBranch branch)

branches

public Vector<UnionBranch> branches()

This is a vector of UnionBranch's.

Returns:

a Vector of UnionBranch

defaultBranch

public void defaultBranch(TypedefEntry branch)

This TypedefEntry describes the type and name for the default branch. Like the entries in the branches vector, only the type and name fields are pertinent.

Parameters:

branch - the TypedefEntry for the default

defaultBranch

public TypedefEntry defaultBranch()

This TypedefEntry describes the type and name for the default branch. Like the entries in the branches vector, only the type and name fields are pertinent.

Returns:

TypedefEntry for the default

addContained

public void addContained(SymtabEntry entry)

contained

public Vector<SymtabEntry> contained()

This is a vector of SymtabEntrys. It itemizes any types which this union contains. For example:

      union A
      switch (long)
      {
        case 0: long x;
        case 1:
          Struct B
          {
            long a;
            long b;
          } y;
      }
      

Struct B is contained within union A.

Returns:

a Vector of SymtabEntrys contained within

has

boolean has(Expression label)

has

boolean has(TypedefEntry typedef)
