public PyObject __eq__(PyObject o)

Overrides org.python.core.PyObject.__eq__.

the object to compare this with.

Returns:PyObject

the result of the comparison.

hashCodeback to summary
public int hashCode()

Overrides org.python.core.PyObject.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

a hash code value for this object

indicesback to summary
public PyObject indices(PyObject len)
indices2back to summary
public static PyObject[] indices2(PyObject obj, PyObject start, PyObject stop)

Calculate indices for the deprecated __get/set/delslice__ methods.

Parameters
obj:PyObject

the object being sliced

start:PyObject

the slice operation's start

stop:PyObject

the slice operation's stop

Returns:PyObject[]

an array with start at index 0 and stop at index 1

indicesExback to summary
public int[] indicesEx(int length)

Calculates the actual indices of a slice with this slice's start, stop, step and slicelength values for a sequence of length len.

Returns:int[]

an array with the start at index 0, stop at index 1, step at index 2 and slicelength at index 3

refersDirectlyToback to summary
public boolean refersDirectlyTo(PyObject ob)

Implements org.python.core.Traverseproc.refersDirectlyTo.

Doc from org.python.core.Traverseproc.refersDirectlyTo.

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

Returns:String

a string representation of the object

@Override

traverseback to summary
public int traverse(Visitproc visit, Object arg)

Implements org.python.core.Traverseproc.traverse.

Doc from org.python.core.Traverseproc.traverse.

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.
