Debugging information

---

universalScope

java.util.Hashtable universalScope

Universal scope

---

globalScope

java.util.Hashtable globalScope

Global scope

---

subroutineScope

java.util.Stack subroutineScope

Subroutine scope

---

onPageEnd

java.util.Vector onPageEnd

Vector of objects to call OnPageEnd to

---

optionExplicit

boolean optionExplicit

Are we option explicit?

Constructor Detail

AspContext

public AspContext(java.util.Hashtable universalScope)

Constructor.

Method Detail

clone

protected java.lang.Object clone()

This function clones this context.

---

inDirectScope

public boolean inDirectScope(IdentNode ident)

This function determines if a variable is directly in scope. This is slightly different from inScope, as the variable is not tested against the global scope if we are in a subroutine.

---

inScope

public boolean inScope(IdentNode ident)

This function determines if a variable is in scope.

---

forceScope

public void forceScope(IdentNode ident)

This function forces an identifier's scope to the current context.

---

getValue

public java.lang.Object getValue(IdentNode ident)
                          throws AspException

This function obtains the value of a variable

---

setValue

public void setValue(IdentNode ident,
                     java.lang.Object value)
              throws AspException

Set the value of an identifier.

---

setOptionExplicit

void setOptionExplicit()
                 throws AspException

Sets the option explicit flag.

---

pushSubroutineScope

void pushSubroutineScope(java.util.Hashtable scope)
                   throws AspException

Pushes a new subroutine scope onto the scope stack.

---

popSubroutineScope

java.util.Hashtable popSubroutineScope()
                                 throws AspException

Pops a subroutine scope off of the scope stack.

---

getAspServer

public Server getAspServer()
                    throws AspException

Utility function to obtain the Server object. XXX Should this be here, or in a separate class?

---

getAspSession

public Session getAspSession()
                      throws AspException

Utility function to obtain the Session object.

---

getAspApplication

public Application getAspApplication()
                              throws AspException

Utility function to obtain the Application object.

---

getAspRequest

public Request getAspRequest()
                      throws AspException

Utility function to obtain the Request object.

---

getAspResponse

public Response getAspResponse()
                        throws AspException

Utility function to obtain the Response object.

---

addOnPageEnd

public void addOnPageEnd(java.lang.Object obj)

callOnPageStart

void callOnPageStart(java.lang.Object obj)

Calls the OnPageStart method of a particular object.

---

resumeNext

boolean resumeNext()
             throws AspException

This utility function checks if ResumeNext is in effect.

---

processException

public void processException(java.lang.Exception ex,
                             DebugContext ctx)
                      throws AspException

This function handles error processing.
