public PyFrame(PyBaseCode code,
       PyObject locals,
       PyObject globals,
       PyObject builtins)

PyFrame

public PyFrame(PyBaseCode code,
       PyObject globals)

Method Detail

getGeneratorInput

public java.lang.Object getGeneratorInput()

checkGeneratorInput

public java.lang.Object checkGeneratorInput()

getLocals

public PyObject getLocals()

Return the locals dict. First merges the fast locals into f_locals, then returns the updated f_locals.

Returns:

a PyObject mapping of locals

getTrace

public PyObject getTrace()

setTrace

public void setTrace(PyObject trace)

delTrace

public void delTrace()

getf_locals

public PyObject getf_locals()

Return the current f_locals dict.

Returns:

a PyObject mapping of locals

setline

public void setline(int line)

Track the current line number. Called by generated code. This is not to be confused with the CPython method frame_setlineno() which causes the interpreter to jump to the given line.

getline

public int getline()

getlocal

public PyObject getlocal(int index)

getname

public PyObject getname(java.lang.String index)

getglobal

public PyObject getglobal(java.lang.String index)

setlocal

public void setlocal(int index,
            PyObject value)

setlocal

public void setlocal(java.lang.String index,
            PyObject value)

setglobal

public void setglobal(java.lang.String index,
             PyObject value)

dellocal

public void dellocal(int index)

dellocal

public void dellocal(java.lang.String index)

delglobal

public void delglobal(java.lang.String index)

getclosure

public PyObject getclosure(int index)

getderef

public PyObject getderef(int index)

setderef

public void setderef(int index,
            PyObject value)

to_cell

public void to_cell(int parm_index,
           int env_index)
