�Zdd�Zddd�ZdS)zUtilities for defining xmethods�N�c@seZdZdZdd�ZdS)�XMethoda�Base class (or a template) for an xmethod description.

    Currently, the description requires only the 'name' and 'enabled'
    attributes.  Description objects are managed by 'XMethodMatcher'
    objects (see below).  Note that this is only a template for the
    interface of the XMethodMatcher.methods objects.  One could use
    this class or choose to use an object which supports this exact same
    interface.  Also, an XMethodMatcher can choose not use it 'methods'
    attribute.  In such cases this class (or an equivalent) is not used.

    Attributes:
        name: The name of the xmethod.
        enabled: A boolean indicating if the xmethod is enabled.

rrrr	rsrc@s eZdZdZdd�Zdd�ZdS)�XMethodMatchera�Abstract base class for matching an xmethod.

    When looking for xmethods, GDB invokes the `match' method of a
    registered xmethod matcher to match the object type and method name.
    The `match' method in concrete classes derived from this class should
    return an `XMethodWorker' object, or a list of `XMethodWorker'
    objects if there is a match (see below for 'XMethodWorker' class).

    Attributes:
        name: The name of the matcher.
        enabled: A boolean indicating if the matcher is enabled.
        methods: A sequence of objects of type 'XMethod', or objects
            which have at least the attributes of an 'XMethod' object.
            This list is used by the 'enable'/'disable'/'info' commands to
            enable/disable/list the xmethods registered with GDB.  See
            the 'match' method below to know how this sequence is used.
            This attribute is None if the matcher chooses not have any
            xmethods managed by it.

        Args:

        whose corresponding 'XMethod' descriptor object is enabled should be
        returned.

XMethodWorkera8Base class for all xmethod workers defined in Python.

    An xmethod worker is an object which matches the method arguments, and
    invokes the method when GDB wants it to.  Internally, GDB first invokes the
    'get_arg_types' method to perform overload resolution.  If GDB selects to
    invoke this Python xmethod, then it invokes it via the overridden
    '__call__' method.  The 'get_result_type' method is used to implement
    'ptype' on the xmethod.

    Derived classes should override the 'get_arg_types', 'get_result_type'
    and '__call__' methods.
    cCr)a�Return arguments types of an xmethod.

        A sequence of gdb.Type objects corresponding to the arguments of the
        xmethod are returned.  If the xmethod takes no arguments, then 'None'
        or an empty sequence is returned.  If the xmethod takes only a single
        argument, then a gdb.Type object or a sequence with a single gdb.Type
        element is returned.

        Args:

                gdb.Value object.  The first element is the 'this' pointer
                value.  These are the same arguments passed to '__call__'.

        Returns:
            A gdb.Type object representing the type of the result of the
            xmethod.

rc@s0eZdZdZGdd�de�Zdd�Zdd�ZdS)	�SimpleXMethodMatchera�A utility class to implement simple xmethod mathers and workers.

    See the __init__ method below for information on how instances of this
    class can be used.

    For simple classes and methods, one can choose to use this class.  For
    complex xmethods, which need to replace/implement template methods on
    possibly template classes, one should implement their own xmethod
    matchers and workers.  See py-xmethods.py in testsuite/gdb.python
    directory of the GDB source tree for examples.
