Returns all objects in slot I of table Tab. If argument I is out of range, the function fails with reason badarg. When dumping the table, some information about the table is dumped to a header at the beginning of the dump. This information contains data about the table type, name, protection, size, version, and if it is a named table. It also contains notes about what extended information is added to the file, which can be a count of the objects in the file or a MD5 sum of the header and records in the file.
The size field in the header might not correspond to the number of records in the file if the table is public and records are added or removed from the table during dumping. Public tables updated during dump, and that one wants to verify when reading, needs at least one field of extended information for the read verification process to be reliable later. The number of objects written to the file is noted in the file footer, so file truncation can be verified even if the file was updated during dump.
The header and objects in the file are checksummed using the built-in MD5 functions. The MD5 sum of all objects is written in the file footer, so that verification while reading detects the slightest bitflip in the file data.
Using this costs a fair amount of CPU time. If option sync is set to true , it ensures that the content of the file is written to the disk before tab2file returns. The name of the dumped table. If the table is not saved as a named table, this field has no significance when loading the table from file. This type is used when loading the table again.
The protection of the dumped table that is, private , protected , or public. A table loaded from the file gets the same protection. Notice that when a named table is loaded from a file, there cannot exist a table in the system with the same name. The keypos of the table dumped to file, which is used when loading the table again. The number of objects in the table when the table dump to file started. For a public table, this number does not need to correspond to the number of objects saved to the file, as objects can have been added or deleted by another process during table dump.
Notice that this function only tells which information is present, not the values in the file footer. When that is not possible, the whole table is traversed.
Option traverse determines how this is done:. The difference is that the match specification is explicitly specified. This is how to state match specifications that cannot easily be expressed within the syntax provided by QLC.
Returns and removes a list of all objects with key Key in table Tab. The function both tests MatchSpec for "syntactic" correctness and runs the match specification against object Tuple. The Dets table is emptied before the objects are inserted.
This function provides an efficient way to update one or more counters, without the trouble of having to look up an object, update the object by incrementing an element, and insert the resulting object into the table again. This function destructively update the object with key Key in table Tab by adding Incr to the element at position Pos. The new counter value is returned. If a Threshold is specified, the counter is reset to value SetValue if the following conditions occur:.
A list of UpdateOp can be supplied to do many update operations within the object. The operations are carried out in the order specified in the list. If the same counter position occurs more than once in the list, the corresponding counter is thus updated many times, each time based on the previous result.
The return value is a list of the new counter values from each update operation in the same order as in the operation list. If an empty list is specified, nothing is updated and an empty list is returned. If the function fails, no updates are done. If a default object Default is specified, it is used as the object to be updated if the key is missing from the table.
The value in place of the key is ignored and replaced by the proper key value. The return value is as if the default object had not been used, that is, a single updated element or a list of them. The function fails with reason badarg in the following situations:.
This function provides an efficient way to update one or more elements within an object, without the trouble of having to look up, update, and write back the entire object. This function destructively updates the object with key Key in table Tab. The element at position Pos is given the value Value. If the same position occurs more than once in the list, the last value in the list is written.
If the list is empty or the function fails, no updates are done. The function is also atomic in the sense that other processes can never see any intermediate results.
Returns true if an object with key Key is found, otherwise false. This function returns the tid of the named table identified by TableName , or undefined if no such table exists. The tid can be used in place of the table name in all operations, which is slightly faster since the name does not have to be resolved on each call. If the table is deleted, the tid will be invalid even if another named table is created with the same name.
Module Summary. Functions in this module fail by raising an error exception with error reason: badarg If any argument has the wrong format. There are different ways to traverse through the objects of a table. Moreover, traversals not done in a safe way, on tables where keys are inserted or deleted during the traversal, may yield the following undesired effects: Any key may be missed. Any key may be found more than once.
The traversal may fail with badarg exception if keys are deleted. Data Types. Deletes the entire table Tab. Equivalent to file2tab Filename, []. The return value is the resulting match specification. Displays information about all ETS tables on a terminal. Browses table Tab on a terminal. If the table is not fixed at all, the call returns false. The function returns the number of objects matched. The function returns the number of objects deleted from the table. The function returns the total number of replaced objects.
Dumps table Tab to file Filename. It took Muren and his team weeks to find the right spot to film a low moon among trees, so they used maps and charts to coordinate the scene once they found the right spot. In the shot, Elliott and E. You can see them acting uncharacteristically hostile in the video above.
Once finished, E. The standing ovation went on for another 15 minutes after the credits rolled, and Spielberg knew he had hit the perfect mark. Following Cannes, the film was released in the United States on June 11, , and would go on to overtake Star Wars as the highest-grossing film of all time—a record it would hold until , when it was beaten by another Spielberg film, Jurassic Park.
Spielberg held personal previews like the one with Lucas for his friends and colleagues, but he would also go on to screen the film at the White House for then-President Ronald Reagan and the First Lady, Nancy Reagan. The director recalled sitting next to the President for the show, and even thought he saw Reagan shed a tear or two. When the film was screened for newlyweds Prince Charles and Princess Diana, Spielberg and the stars in attendance were bizarrely ushered backstage the moment the film ended.
Columbia Pictures had optioned the concept with Peter Sellers and Marlon Brando in the lead roles, but legal troubles forced Ray to abandon the project. When E. Ray told the press, " E. Both Spielberg and Mathison wrote a story treatment for a potential sequel to E. The story describes a plot in which Elliott and his friends are abducted by a mutated race of E.
Eventually, E. Ultimately, Spielberg decided not to do a sequel because doing so "would do nothing but rob the original of its virginity. A novelized sequel by author William Kotzwinkle—who also penned the novelization of the original film—was published in Additional Sources: E.
