imas.backends.imas_core.al_context.LazyALArrayStructChildContext¶

class imas.backends.imas_core.al_context.LazyALArrayStructChildContext(parent_ctx: LazyALContext | None = None, method: Callable | None = None, args: tuple = (), *, dbentry: ALDBEntryImpl | None = None, nbc_map: NBCPathMap | None = None, time_mode: int | None = None)¶

Bases: LazyALContext

Subclass that allows an array of structures child structure to read data.

__init__(parent_ctx: LazyALContext | None = None, method: Callable | None = None, args: tuple = (), *, dbentry: ALDBEntryImpl | None = None, nbc_map: NBCPathMap | None = None, time_mode: int | None = None)¶

Methods

__init__([parent_ctx, method, args, ...])
arraystruct_action(path, timebase, size)	Lazily start an arraystruct action.
get_child(child)	Retrieve a child entry from the field.
get_context()	Create and yield the actual ALContext.
global_action(path, rwmode)	Lazily start a lowlevel global action, see ALContext.global_action()
slice_action(path, rwmode, time_requested, ...)	Lazily start a lowlevel slice action, see ALContext.slice_action()
timerange_action(path, rwmode, tmin, tmax, ...)	Lazily start a lowlevel timerange action, see ALContext.timerange_action().

Attributes

args	Additional arguments we need to supply to self.method
context	Potential weak reference to opened context.
dbentry	ALDBEntryImpl object that created us, or our parent.
dbentry_ctx	The ALContext of the ALDBEntryImpl at the time of get/get_slice.
method	Method we need to call with our parent ALContext to get our ALContext.
nbc_map	NBC map for _get_children() when lazy loading IDSStructArray items.
parent_ctx	Optional parent context that provides our parent ALContext.
time_mode	Time mode used by the IDS being lazy loaded.

args¶

Additional arguments we need to supply to self.method

arraystruct_action(path: str, timebase: str, size: int) → LazyALArrayStructContext¶

Lazily start an arraystruct action.

context¶

Potential weak reference to opened context.

dbentry¶

ALDBEntryImpl object that created us, or our parent.

dbentry_ctx¶

The ALContext of the ALDBEntryImpl at the time of get/get_slice.

get_child(child)¶

Retrieve a child entry from the field.

Parameters:

child : str¶

The name or identifier of the child entry to retrieve.

Returns:

The child entry retrieved from the database.

get_context() → ALContext¶

Create and yield the actual ALContext.

global_action(path: str, rwmode: int) → Iterator[LazyALContext]¶

Lazily start a lowlevel global action, see ALContext.global_action()

method¶

Method we need to call with our parent ALContext to get our ALContext.

nbc_map¶

NBC map for _get_children() when lazy loading IDSStructArray items.

parent_ctx : LazyALArrayStructContext¶

Optional parent context that provides our parent ALContext.

slice_action(path: str, rwmode: int, time_requested: float, interpolation_method: int) → Iterator[LazyALContext]¶

Lazily start a lowlevel slice action, see ALContext.slice_action()

time_mode¶

Time mode used by the IDS being lazy loaded.

timerange_action(path: str, rwmode: int, tmin: float, tmax: float, dtime: ndarray | None, interpolation_method: int) → Iterator[LazyALContext]¶

Lazily start a lowlevel timerange action, see ALContext.timerange_action().
