Method Detail

__eq__back to summary
public PyObject __eq__(PyObject other)

Overrides org.python.core.PyObject.__eq__.

Doc from org.python.core.PyObject.__eq__.

Equivalent to the standard Python __eq__ method.

Parameters
other:PyObject

the object to compare this with.

Returns:PyObject

the result of the comparison.

__ne__back to summary
public PyObject __ne__(PyObject other)

Overrides org.python.core.PyObject.__ne__.

Doc from org.python.core.PyObject.__ne__.

Equivalent to the standard Python __ne__ method.

Parameters
other:PyObject

the object to compare this with.

Returns:PyObject

the result of the comparison.

callback to summary
pack-priv void call()
equalsback to summary
public boolean equals(Object ob_other)

Overrides org.python.core.PyObject.equals.

Doc from org.python.core.PyObject.equals.

Should almost never be overridden. If overridden, it is the subclasses responsibility to ensure that a.equals(b) == true iff cmp(a,b) == 0

Parameters
ob_other:Object

Doc from java.lang.Object.equals.

the reference object with which to compare.

Returns:boolean

Doc from java.lang.Object.equals.

true if this object is the same as the obj argument; false otherwise.

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

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.

Annotations
@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.
