Method Detail

getFactory

Factory getFactory()

isApplyingTransformer

boolean isApplyingTransformer()

Flag determining whether to apply transformer or not. That means implementations ought to provide alternative (e.g., conservative) solutions when not transforming terms.

Returns:

setApplyTransformer

void setApplyTransformer(boolean value)

getTermVisitor

net.sourceforge.czt.util.Visitor<R> getTermVisitor()

Returns a visitor implementing a VCG protocol.

Type Parameters:

R -

Parameters:

resClass -

Returns:

visit

R visit(net.sourceforge.czt.base.ast.Term term)

Visit the given term. At this point only non-null terms are allowed. Default values for null terms are to be handled by corresponding collector classes.

Parameters:

term -

Returns:

Throws:

net.sourceforge.czt.util.CztException - if term is null
