- Interp interp ()
-
If an error occurs while converting an object to be a list object,
an error message is left in the interpreter's result object
unless interp is NULL.
- TclObject tobj ()
-
Points to the list object to be manipulated.
If tobj does not already point to a list object,
an attempt will be made to convert it to one.
- TclObject elem ()
-
Points to a list object containing elements to be appended onto tobj.
- TclObject elts[] ()
-
An array of TclObjects to reaplace those in the list object tobj.
- int index ()
-
The index of the elemtent of tobj in question.
- int count ()
-
The number of elemtents of the tobj to replace.
- int from ()
-
The index of the first replacement element in elts.
- int to ()
-
The index of the last replacement element in elts.
The TclList class is used to create, modify and read from Tcl list
objects. All of the methods defined below attempt to change the
internal representation of tobj parameters to TclList. If such a
conversion fails (e.g., the string value of tobj is not a proper Tcl
list), a TclException is thrown, and an appropriate error message
is left in interp's result if interp is not null.
Tcl list objects have an internal representation that supports
the efficient indexing and appending.
The procedures described in this man page are used to
create, modify, index, and append to Tcl list objects from Java code.
In all cases where tobj is an argument, if tobj is not a
TclList, then an attempt is made to convert it to a TclList. If
the attempt fails, a TclException is thrown.
- newInstance
-
The newInstance method creates and returns a new empty TclList.
- append
-
The append method adds one object, elem, to the end of the list
object referenced by tobj. After appending the element,
append increments the element's reference count since tobj
now also refers to it.
- getLength
-
The getLength method returns the number of elements in tobj.
- getElements
-
The getElements method converts the TclList tobj to an array of
TclObjects. The objects referenced by the returned array should be
treated as readonly, and their ref counts are not incremented.
- index
-
The index method returns a pointer to the indexth element of
tobj. If index is negative or greater than or equal to
the number of elements in the list, null is returned.
- replace
-
The replace mehtod replaces zero or more elements of the list referenced by
tobj with the objects in elts ranging from from to
to.
