Variable
public Variable(String name,
Type type)
allocateLocal
public void allocateLocal(CodeAttr code)
Allocate slots for a local variable (or parameter).
dead
public final boolean dead()
freeLocal
public void freeLocal(CodeAttr code)
hasMoreElements
public final boolean hasMoreElements()
isAssigned
public final boolean isAssigned()
Returns true iff assigned to a local variable slot.
Only relevant if isSimple ().
isParameter
public final boolean isParameter()
isSimple
public final boolean isSimple()
Returns true for a "simple" variable.
A "simple" Variable can be stack-allocated using standard local
variable slots. It is allocated by the codegen package.
A non-simple variable may need heap allocation, or more more
complex access; it is basically ignored by the codegen package,
and must be managed by higher layers.
nextElement
public Object nextElement()
reserveLocal
public boolean reserveLocal(int varIndex,
CodeAttr code)
Assign a local variable to a given local variable slot.
varIndex
- the index of the local variables.
- true iff we succeeded (i.e. the slot was unused)
setParameter
public final void setParameter(boolean parameter)
setSimple
public final void setSimple(boolean simple)
toString
public String toString()
