obspy.io.segy.core.LazyTraceHeaderAttribDict

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

Bases: obspy.core.util.attribdict.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.

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.
