Method Detail

visit

boolean visit(AstNode node)

Visits an AST node.

Parameters:

node - the AST node. Will never visit an AstRoot node, since the AstRoot is where the visiting begins.

Returns:

true if the children should be visited. If false, the subtree rooted at this node is skipped. The node argument should never be null -- the individual AstNode classes should skip any children that are not present in the source when they invoke this method.
