IllegalArgumentException}

CatchClause
nodes. If there are no catch
clauses, returns an immutable empty list.
public void setCatchClauses(java.util.List<CatchClause> catchClauses)
CatchClause
nodes. Also sets their parents
to this node. May be null
. Replaces any existing catch
clauses for this node.

public void setFinallyBlock(AstNode finallyBlock)
null
.
public int getFinallyPosition()
finally
keyword, if present, or -1
public void setFinallyPosition(int finallyPosition)
finally
keyword, if present, or -1
public java.lang.String toSource(int depth)
AstNode
Note: if the parser was in error-recovery mode, some AST nodes may have
null
children that are expected to be non-null
when no errors are present. In this situation, the behavior of the
toSource
method is undefined: toSource
implementations may assume that the AST node is error-free, since it is
intended to be invoked only at runtime after a successful parse.
toSource
in class AstNode
depth
- the current recursion depth, typically beginning at 0
when called on the root node.public void visit(NodeVisitor v)
visit
in class AstNode
v
- the object to call with this node and its children
