Insert event in queue, and keep it sorted assuming queue is sorted.
If event is already in queue, insert it to the right of the rightmost
event (to keep FIFO order).
Optional args lo (default 0) and hi (default len(a)) bound the
slice of a to be searched.
Args:
event: a (time in sec since unix epoch, callback, args, kwds) tuple.

Helper for GQL parsing to extract values from GQL expressions.
This can extract the value from a GQL literal, return a Parameter
for a GQL bound parameter (:1 or :foo), and interprets casts like
KEY(...) and plain lists of values like (1, 2, 3).
Args:
func: A string indicating what kind of thing this is.
args: One or more GQL values, each integer, string, or GQL literal.

def _apply(self, key_value_map):
"""Apply the filter to values extracted from an entity.
Think of self.match_keys and self.match_values as representing a
table with one row. For example:
match_keys = ('name', 'age', 'rank')
match_values = ('Joe', 24, 5)
(Except that in reality, the values are represented by tuples
produced by datastore_types.PropertyValueToKeyValue().)
represents this table:
| name | age | rank |
+---------+-------+--------+
| 'Joe' | 24 | 5 |
Think of key_value_map as a table with the same structure but
(potentially) many rows. This represents a repeated structured
property of a single entity. For example:
{'name': ['Joe', 'Jane', 'Dick'],
'age': [24, 21, 23],
'rank': [5, 1, 2]}
represents this table:
| name | age | rank |
+---------+-------+--------+
| 'Joe' | 24 | 5 |
| 'Jane' | 21 | 1 |
| 'Dick' | 23 | 2 |
We must determine wheter at least one row of the second table
exactly matches the first table. We need this class because the
datastore, when asked to find an entity with name 'Joe', age 24
and rank 5, will include entities that have 'Joe' somewhere in the
name column, 24 somewhere in the age column, and 5 somewhere in
the rank column, but not all aligned on a single row. Such an

Args:
callback: A function or tasklet to be applied to each result; see below.
merge_future: Optional Future subclass; see below.
**q_options: All query options keyword arguments are supported.
Callback signature: The callback is normally called with an entity
as argument. However if keys_only=True is given, it is called
with a Key. Also, when pass_batch_into_callback is True, it is
called with three arguments: the current batch, the index within
the batch, and the entity or Key at that index. The callback can
return whatever it wants. If the callback is None, a trivial
callback is assumed that just returns the entity or key passed in
(ignoring produce_cursors).
Optional merge future: The merge_future is an advanced argument
that can be used to override how the callback results are combined
into the overall map() return value. By default a list of
callback return values is produced. By substituting one of a
small number of specialized alternatives you can arrange
otherwise. See tasklets.MultiFuture for the default
implementation and a description of the protocol the merge_future
object must implement the default. Alternatives from the same
module include QueueFuture, SerialQueueFuture and ReducingFuture.
Returns:
When the query has run to completion and all callbacks have
returned, map() returns a list of the results of all callbacks.
(But see 'optional merge future' above.)

**q_options: All query options keyword arguments are supported.
Callback signature: The callback is normally called with an entity
as argument. However if keys_only=True is given, it is called
with a Key. Also, when pass_batch_into_callback is True, it is
called with three arguments: the current batch, the index within
the batch, and the entity or Key at that index. The callback can
return whatever it wants. If the callback is None, a trivial
callback is assumed that just returns the entity or key passed in
(ignoring produce_cursors).
Optional merge future: The merge_future is an advanced argument
that can be used to override how the callback results are combined
into the overall map() return value. By default a list of
callback return values is produced. By substituting one of a
small number of specialized alternatives you can arrange
otherwise. See tasklets.MultiFuture for the default
implementation and a description of the protocol the merge_future
object must implement the default. Alternatives from the same
module include QueueFuture, SerialQueueFuture and ReducingFuture.
Returns:
When the query has run to completion and all callbacks have
returned, map() returns a list of the results of all callbacks.
(But see 'optional merge future' above.)

Converts a function into a decorator that optionally accepts keyword
arguments in its declaration.
Example usage:
@utils.decorator
def decorator(func, args, kwds, op1=None):
... apply op1 ...
return func(*args, **kwds)
# Form (1), vanilla
@decorator
foo(...)
...
# Form (2), with options
@decorator(op1=5)
foo(...)
...
Args:
wrapped_decorator: A function that accepts positional args (func, args,
kwds) and any additional supported keyword arguments.
Returns:
A decorator with an additional 'wrapped_decorator' property that is set to
the original function.
