Method Detail
-
apply2
public Object apply2(Object arg1, Object arg2)
- Specified by:
apply2
in classProcedure2
-
getSlotValue
public static Object getSlotValue(boolean isStatic, Object obj, String name, String fname, String getName, String isName, Language language)
The actual gets of finding the field value. The compiler emits calls to this method if the field name is literal but the actual field is not known at compile time. This speeds lookup a bit. If fname equals "length" or "class", it is assumed to be interned.
-
lookupMember
public static Member lookupMember(ObjectType clas, String name, ClassType caller)
Get a named property - field or member class or 'get' accessor method.- Parameters:
clas
- the class type declaring the property.name
- the source (unmangled) name of the property.
-
compile
public void compile(ApplyExp exp, Compilation comp, Target target)
- Specified by:
compile
in interfaceInlineable
-
getSetter
public Procedure getSetter()
-
makeGetField
public static ApplyExp makeGetField(Expression value, String fieldName)
Convenience method to make an Expression that gets the value of a field.- Parameters:
value
- evaluates to object that has the named fieldfieldName
- name of field in value- Returns:
- expression that get the name field from value
