    LZMACompressor(format=FORMAT_XZ, check=-1, preset=None, filters=None)
    
    Create a compressor object for compressing data incrementally.
    
    format specifies the container format to use for the output. This can
    be FORMAT_XZ (default), FORMAT_ALONE, or FORMAT_RAW.
    
    check specifies the integrity check to use. For FORMAT_XZ, the default
    is CHECK_CRC64. FORMAT_ALONE and FORMAT_RAW do not support integrity
    checks; for these formats, check must be omitted, or be CHECK_NONE.
    
    The settings used by the compressor can be specified either as a
    preset compression level (with the 'preset' argument), or in detail
    as a custom filter chain (with the 'filters' argument). For FORMAT_XZ
    and FORMAT_ALONE, the default is to use the PRESET_DEFAULT preset
    level. For FORMAT_RAW, the caller must always specify a filter chain;
    the raw compressor does not support preset compression levels.
    
    preset (if provided) should be an integer in the range 0-9, optionally
    OR-ed with the constant PRESET_EXTREME.
    
    filters (if provided) should be a sequence of dicts. Each dict should
    have an entry for "id" indicating the ID of the filter, plus
    additional entries for options to the filter.
    
    For one-shot compression, use the compress() function instead.
