apply2
public java.lang.Object apply2(java.lang.Object arg1,
java.lang.Object arg2)
- Specified by:
apply2
in class Procedure2
getSlotValue
public static java.lang.Object getSlotValue(boolean isStatic,
java.lang.Object obj,
java.lang.String name,
java.lang.String fname,
java.lang.String getName,
java.lang.String isName,
Language language)
- The actual gets of finding the field value.
The compiler emits calls to this method if the field name is literals
but the actual field is not known at compile time.
This speeds lookup a bit.
setN
public void setN(java.lang.Object[] args)
- Overrides:
setN
in class Procedure
set2
public void set2(java.lang.Object obj,
java.lang.Object name,
java.lang.Object value)
lookupMember
public static Member lookupMember(ObjectType clas,
java.lang.String name,
ClassType caller)
- Get a named property - field 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 interface Inlineable
getReturnType
public Type getReturnType(Expression[] args)
- Description copied from class:
Procedure
- Semi-deprecated - instead should be set at Inline time. FIXME
- Overrides:
getReturnType
in class Procedure
getSetter
public Procedure getSetter()
- Specified by:
getSetter
in interface HasSetter
- Overrides:
getSetter
in class Procedure
makeGetField
public static ApplyExp makeGetField(Expression value,
java.lang.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
