Constructor Detail

AbstractBlock_c

public AbstractBlock_c(Position pos,
                       java.util.List statements)
Method Detail

statements

public java.util.List statements()
Get the statements of the block.

Specified by:
statements in interface Block
Returns:
A list of Stmt.

statements

public Block statements(java.util.List statements)
Set the statements of the block.

Specified by:
statements in interface Block
Parameters:
statements - A list of Stmt.

append

public Block append(Stmt stmt)
Append a statement to the block.

Specified by:
append in interface Block

prepend

public Block prepend(Stmt stmt)
Prepend a statement to the block.

Specified by:
prepend in interface Block

reconstruct

protected AbstractBlock_c reconstruct(java.util.List statements)
Reconstruct the block.


visitChildren

public Node visitChildren(NodeVisitor v)
Visit the children of the block.

Specified by:
visitChildren in interface NodeOps
Overrides:
visitChildren in class Node_c

enterScope

public Context enterScope(Context c)
Description copied from interface: NodeOps
Push a new scope upon entering this node, and add any declarations to the context that should be in scope when visiting children of this node. This should not update the old context imperatively. Use addDecls when leaving the node for that.

Specified by:
enterScope in interface NodeOps
Overrides:
enterScope in class Node_c
Parameters:
c - the current Context
Returns:
the Context to be used for visiting this node.

prettyPrint

public void prettyPrint(CodeWriter w,
                        PrettyPrinter tr)
Write the block to an output file.

Specified by:
prettyPrint in interface NodeOps
Overrides:
prettyPrint in class Node_c

entry

public Term entry()
Description copied from interface: Term
Return the first (sub)term performed when evaluating this term.

Specified by:
entry in interface Term
Specified by:
entry in class Term_c

acceptCFG

public java.util.List acceptCFG(CFGBuilder v,
                                java.util.List succs)
Description copied from interface: Term
Visit this node, calling calling v.edge() for each successor in succs, if data flows on that edge.

Specified by:
acceptCFG in interface Term
Specified by:
acceptCFG in class Term_c

toString

public java.lang.String toString()
Overrides:
toString in class Node_c
