"skip the current subtree" means reading it but doing nothing?
then write grammar rules which walk that subtree and do nothing with it, maybe 
like:
 bool_function_content[Boolean value]

 	:	{value != null && value.booleanValue()}? => function_content*
	|            {value != null && !value.booleanValue()}? => 
overread_function_content*
 	;


cheers,
 Michael
