setChildIndex

public void setChildIndex(int index)

dottedNameListToString

public static java.lang.String dottedNameListToString(java.util.List<Name> names)

Converts a list of Name to a dotted-name string. Because leading dots are indexable identifiers (referring to parent directories in relative imports), a Name list may include leading dots, but not dots between names.

toString

public java.lang.String toString()

Overrides:

toString in class PyObject

toStringTree

public java.lang.String toStringTree()

accept

public <R> R accept(VisitorIF<R> visitor)
             throws java.lang.Exception

Throws:

java.lang.Exception

traverse

public void traverse(VisitorIF<?> visitor)
              throws java.lang.Exception

Throws:

java.lang.Exception

getChild

public PythonTree getChild(int i)

getChildren

public java.util.List<PythonTree> getChildren()

Get the children internal List; note that if you directly mess with the list, do so at your own risk.

getFirstChildWithType

public PythonTree getFirstChildWithType(int type)

getChildCount

public int getChildCount()

addChild

public void addChild(PythonTree t)

Add t as child of this node. Warning: if t has no children, but child does and child isNil then this routine moves children to t via t.children = child.children; i.e., without copying the array.

addChildren

public void addChildren(java.util.List<PythonTree> kids)

Add all elements of kids list as children of this node

setChild

public void setChild(int i,
                     PythonTree t)

deleteChild

public java.lang.Object deleteChild(int i)

replaceChildren

public void replaceChildren(int startChildIndex,
                            int stopChildIndex,
                            java.lang.Object t)

Delete children from start to stop and replace with t even if t is a list (nil-root tree). num of children can increase or decrease. For huge child lists, inserting children can force walking rest of children to set their childindex; could be slow.

freshenParentAndChildIndexes

public void freshenParentAndChildIndexes()

Set the parent and child index values for all child of t

freshenParentAndChildIndexes

public void freshenParentAndChildIndexes(int offset)

traverse

public int traverse(Visitproc visit,
                    java.lang.Object arg)

Description copied from interface: Traverseproc

Traverses all directly contained PyObjects. Like in CPython, arg must be passed unmodified to visit as its second parameter. If Visitproc.visit(PyObject, Object) returns nonzero, this return value must be returned immediately by traverse. Visitproc.visit(PyObject, Object) must not be called with a null PyObject-argument.

Specified by:

traverse in interface Traverseproc

refersDirectlyTo

public boolean refersDirectlyTo(PyObject ob)

Description copied from interface: Traverseproc

Optional operation. Should only be implemented if it is more efficient than calling Traverseproc.traverse(Visitproc, Object) with a visitproc that just watches out for ob. Must return false if ob is null.

Specified by:

refersDirectlyTo in interface Traverseproc
