Class Method Details

.parse(content, namespaces = {}) ⇒ Enumerator

prefixes in BEL statements; defaults to empty meaning use the DEFINE NAMESPACE definitions in the content

Parameters:

  • content (String, IO) —

    the BEL Script data to parse

  • namespaces (Hash) (defaults to: {}) —

    the Namespace::NamespaceDefinition to use when matching

Returns:

  • (Enumerator) —

    the parsed objects

.parse_chunked(io, namespaces = {}, chunk_length = MAX_LENGTH) ⇒ Enumerator

prefixes in BEL statements; defaults to empty meaning use the DEFINE NAMESPACE definitions in the content

Parameters:

  • io (IO) —

    the BEL Script data to parse; if a String then #parse will be called instead

  • namespaces (Hash) (defaults to: {}) —

    the Namespace::NamespaceDefinition to use when matching

  • chunk_length (Integer) (defaults to: MAX_LENGTH) —

    determines how many bytes are buffered at a time when io is an IO

Returns:

  • (Enumerator) —

    the parsed objects
