Method Detail

computeType

int computeType(DefaultNameSpaceDescription nsd)
          throws ParseException

If this expression is a port selection, computes the overall type: if all ports have tha same type with the exception of the inuout ones, the overall type is the same. If all the ports are inout, the overall is inout. Note that the if a port identifier is from another module (a fqn with more than one node), a parse exception is thrown else, an exception is thrown

instantiate

java.lang.Object instantiate(NameSpace ns,

                       throws ParseException

Overrides:

instantiate in class Symbol

prepareForContSelection

void prepareForContSelection()
                       throws ParseException

Makes this expression a continuous expression

getType

public int getType()

Overrides:

getType in class Symbol
