Method Detail

visitClassType

public java.lang.Object visitClassType(ClassType node,
                              java.lang.Object data)

Add defaults at the Class Level. 1. If the class is SIDL_BASECLASS, implement SIDL_BASEINTERFACE 2. If the class doesn't inherit anything, extend SIDL_BASECLASS TBD: - Should defaults be assigned for class-level splicer blocks? What about C's "int ignore;" and F90's "integer :: placeholder"? - If so, then how should the different kind and number of blocks for each language be handled? (For example, C has two splicer blocks --- _data and _includes --- in it's header while, ignoring method-specific blocks, Java has four --- _imports, _data, _load (for static), and _misc.) - What is the most desirable way of handling default comments in splicer blocks given the different comment syntax for each language?

visitInterfaceType

public java.lang.Object visitInterfaceType(InterfaceType node,
                                  java.lang.Object data)

Add defaults as the interface level 1. If it's not SIDL_BASEINTERFACE, and it has no extends, extend SIDL_BASEINTERFACE

visitMethod

public java.lang.Object visitMethod(Method node,
                           java.lang.Object data)

Method level defaults 1. Add implicit Runtime Exception to every throws list 2. Add default splicer block contents --- at least for the method body. TBD: - What about the default splicer block contents for each F90 method's use?
