obspy.io.segy.core.LazyTraceHeaderAttribDict

class LazyTraceHeaderAttribDict(unpacked_header, unpacked_header_endian, data={})[source]

Bases: AttribDict

This version of AttribDict will unpack header values only if needed.

This saves a huge amount of memory. The disadvantage is that it is no longer possible to use tab completion in e.g. ipython.

This version is used for the SEGY/SU trace headers.

Attributes

`defaults`
`do_not_warn_on`
`readonly`
`warn_on_non_default_key`

Public Methods

`clear`
`copy`
`get`
`items`
`keys`
`pop`	If key is not found, d is returned if given, otherwise KeyError is raised.
`popitem`	as a 2-tuple; but raise KeyError if D is empty.
`setdefault`
`update`
`values`

Private Methods

Warning

Private methods are mainly for internal/developer use and their API might change without notice.

LazyTraceHeaderAttribDict._cast_type(key, value)

Cast type of value to type required in _types dict.

Parameters:

key (str) – The key from __setattr__.
value – The value being set to key.

Returns:

value cast to correct type.

LazyTraceHeaderAttribDict._pretty_str(priorized_keys=[], min_label_length=16)

Return better readable string representation of AttribDict object.

Parameters:

priorized_keys (list[str], optional) – Keywords of current AttribDict which will be shown before all other keywords. Those keywords must exists otherwise an exception will be raised. Defaults to empty list.
min_label_length (int, optional) – Minimum label length for keywords. Defaults to 16.

Returns:

String representation of current AttribDict object.

Special Methods

classmethod LazyTraceHeaderAttribDict.__class_getitem__()

Represent a PEP 585 generic type

E.g. for t = list[int], t.__origin__ is list and t.__args__ is (int,).

LazyTraceHeaderAttribDict.__contains__(key)

LazyTraceHeaderAttribDict.__deepcopy__(*args, **kwargs)[source]

LazyTraceHeaderAttribDict.__delattr__(name)

LazyTraceHeaderAttribDict.__delitem__(name)

LazyTraceHeaderAttribDict.__dir__(): Default dir() implementation.

LazyTraceHeaderAttribDict.__eq__(other)

LazyTraceHeaderAttribDict.__format__(format_spec, /): Default object formatter.

LazyTraceHeaderAttribDict.__ge__(value, /): Return self>=value.

LazyTraceHeaderAttribDict.__getattr__(name)

LazyTraceHeaderAttribDict.__getattribute__(name, /): Return getattr(self, name).

LazyTraceHeaderAttribDict.__getitem__(name)[source]

LazyTraceHeaderAttribDict.__gt__(value, /): Return self>value.

LazyTraceHeaderAttribDict.__init__(unpacked_header, unpacked_header_endian, data={})[source]

LazyTraceHeaderAttribDict.__init_subclass__()

This method is called when a class is subclassed.

The default implementation does nothing. It may be overridden to extend subclasses.

LazyTraceHeaderAttribDict.__iter__()

LazyTraceHeaderAttribDict.__le__(value, /): Return self<=value.

LazyTraceHeaderAttribDict.__len__()

LazyTraceHeaderAttribDict.__lt__(value, /): Return self<value.

LazyTraceHeaderAttribDict.__ne__(value, /): Return self!=value.

LazyTraceHeaderAttribDict.__new__(**kwargs)

LazyTraceHeaderAttribDict.__reduce__(): Helper for pickle.

LazyTraceHeaderAttribDict.__reduce_ex__(protocol, /): Helper for pickle.

LazyTraceHeaderAttribDict.__repr__()

LazyTraceHeaderAttribDict.__setattr__(key, value)

LazyTraceHeaderAttribDict.__setitem__(key, value)

LazyTraceHeaderAttribDict.__sizeof__(): Size of object in memory, in bytes.

LazyTraceHeaderAttribDict.__str__(): Return str(self).

classmethod LazyTraceHeaderAttribDict.__subclasshook__(C)
