Class ForBodyNameSpace  

java.lang.Object
  bsh.NameSpace
      bsh.ForBodyNameSpace

All Implemented Interfaces:

BshClassManager.Listener, NameSource, java.io.Serializable

class ForBodyNameSpace

extends NameSpace

A specialized namespace for the body of a "for" statement. The for statement body acts like a child namespace but only for variables declared or initialized in the forInit() section. Elsewhere variable assignment acts like it is part of the containing block. This namespace takes as an argument a namespace comprising the forInit() variables and allows variables within it to shadow those in the parent namespace. Otherwise all assignments are delegated to the parent namespace. There may be more methods from NameSpace that should be overidden here.

Constructor Detail

ForBodyNameSpace

public ForBodyNameSpace(NameSpace parent,
                        NameSpace forInitNameSpace)

Method Detail

setVariable

public void setVariable(java.lang.String name,
                        java.lang.Object o)
                 throws EvalError

If the variables exists in the forInit space assign it there, otherwise in the parent space.

Overrides:

setVariable in class NameSpace

---

setTypedVariable

public void setTypedVariable(java.lang.String name,
                             java.lang.Class type,
                             java.lang.Object value,
                             boolean isFinal)
                      throws EvalError

If the variables exists in the forInit space assign it there, otherwise in the parent space. Note: this may not make sense... if it exists we'll throw an error, right? this can only happen in the forInit eval, right?

Overrides:

setTypedVariable in class NameSpace

---

forInitSpaceHasVariable

boolean forInitSpaceHasVariable(java.lang.String name)

---

getVariable

public java.lang.Object getVariable(java.lang.String name)

get()s first check the forInit space. If not defined there then they are delegated to the parent space.

Overrides:

getVariable in class NameSpace
