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.
