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.

Visit the children of the block.

Specified by:

visitChildren in interface NodeOps

Overrides:

visitChildren in class Node_c

Parameters:

v - The visitor that will traverse/rewrite the AST.

Returns:

A new AST if a change was made, or this.

enterScope

public Context enterScope(Context c)

Description copied from class: Node_c
