Data Fields | |
ION_EXTRACTOR_SIZE | max_path_length |
ION_EXTRACTOR_SIZE | max_num_paths |
bool | match_relative_paths |
bool | match_case_insensitive |
Extractor configuration to be supplied by the user when opening a new extractor.
bool _ion_extractor_options::match_case_insensitive |
If true
, the extractor will treat paths as case-insensitive.
Defaults to false
.
bool _ion_extractor_options::match_relative_paths |
If true
, the extractor will accept a reader positioned at any valid depth within the data. It will match paths relative to the initial depth of the reader at the start of ion_extractor_match
. For example, if a reader positioned at depth 2 at the field 'foo' in the data {abc:{foo:{bar:baz}}}
is provided to an extractor with match_relative_paths=true
and the registered path (bar)
, the extractor would match on the value baz
. This extractor would finish matching once it exhausted all sibling values (none in this case) at depth 2.
If false
, the extractor requires a reader positioned at depth 0.
Defaults to false
.
ION_EXTRACTOR_SIZE _ion_extractor_options::max_num_paths |
The maximum number of paths that can be registered to this extractor. Defaults to ION_EXTRACTOR_MAX_NUM_PATHS, and may not be greater than ION_EXTRACTOR_MAX_NUM_PATHS.
The closer this value is to the actual number of paths provided to the extractor, the denser the paths can be organized, which may improve performance.
ION_EXTRACTOR_SIZE _ion_extractor_options::max_path_length |
The maximum length of paths that can be registered to this extractor. Defaults to ION_EXTRACTOR_MAX_PATH_LENGTH, and may not be greater than ION_EXTRACTOR_MAX_PATH_LENGTH.
The closer this value is to the length of the longest path registered to the extractor, the denser the paths can be organized, which may improve performance.
