If you're using the latest (perhaps forthcoming, I've lost track)
version of ANTLR:
bool_function_content[Boolean value]
: { value != null && value.booleanValue() }? =>
function_content*
| .*
;
If you're using an older version:
skip : . | ^(. skip*) ;
bool_function_content[Boolean value]
: { value != null && value.booleanValue() }? =>
function_content*
| skip*
;
