EJDB NodeJS API
----------------------------------
<a name="open" />
### EJDB.open(dbFile, openMode)
Open database. Return database instance handle object.
<br/>Default open mode: `JBOWRITER | JBOCREAT`.
<br/>This is blocking function.

---------------------------------------
<a name="close" />
### close()

<a name="isOpen"/>
### isOpen()
Check if database in opened state.
---------------------------------------
<a name="ensureCollection"/>
### ensureCollection(cname, copts)
Automatically creates new collection if it does't exists.
Collection options `copts` applied only for newly created collection.
For existing collections `copts` takes no effect.
Collection options (copts):
* cachedrecords : Max number of cached records in shared memory segment. Default: 0
* records : Estimated number of records in this collection. Default: 65535.
* large : Specifies that the size of the database can be larger than 2GB. Default: false
* compressed : If true collection records will be compressed with DEFLATE compression. Default: false.
<br/>This is blocking function.
__Arguments__

---------------------------------------
<a name="save"/>
### save(cname, jsarr, cb)
Save/update specified JSON objects in the collection.
If collection with `cname` does not exists it will be created.
Each persistent object has unique identifier (OID) placed in the `_id` property.
If a saved object does not have `_id` it will be autogenerated.
To identify and update object it should contains `_id` property.
If callback is not provided this function will be synchronous.
Call variations:
save(cname, <json object>|<Array of json objects>, [options] [cb])
save(cname, <json object>|<Array of json objects>, [cb])
NOTE: Field names of passed JSON objects may not contain `$` and `.` characters,
error condition will be fired in this case.
__Arguments__

* {Array|Object} jsarr Signle JSON object or array of JSON objects to save
* {Function} `[cb]` Callback args: (error, {Array} of OIDs for saved objects)
__Return__
* {Array} of OIDs of saved objects in synchronous mode otherwise returns {undefined}.
--------------------------------------
<a name="load"/>

### remove(cname, oid, cb)
Removes JSON object from the collection.
If callback is not provided this function will be synchronous.
__Arguments__
* {String} cname Name of collection
* {String} oid Object identifier (OID)
* {Function} cb Callback args: (error)
--------------------------------------
<a name="find"/>
### find(cname, qobj, orarr, hints, cb)
Execute query on collection.
EJDB queries inspired by MongoDB (mongodb.org) and follows same philosophy.
Supported queries:
- Simple matching of String OR Number OR Array value:
- {'fpath' : 'val', ...}
- $not Negate operation.
- {'fpath' : {'$not' : val}} //Field not equal to val
- {'fpath' : {'$not' : {'$begin' : prefix}}} //Field not begins with val
- $begin String starts with prefix
- {'fpath' : {'$begin' : prefix}}
- $gt, $gte (>, >=) and $lt, $lte for number types:
- {'fpath' : {'$gt' : number}, ...}
- $bt Between for number types:
- {'fpath' : {'$bt' : [num1, num2]}}
- $in String OR Number OR Array val matches to value in specified array:
- {'fpath' : {'$in' : [val1, val2, val3]}}
- $nin - Not IN
- $strand String tokens OR String array val matches all tokens in specified array:
- {'fpath' : {'$strand' : [val1, val2, val3]}}
- $stror String tokens OR String array val matches any token in specified array:
- {'fpath' : {'$stror' : [val1, val2, val3]}}
- $exists Field existence matching:
- {'fpath' : {'$exists' : true|false}}
- $icase Case insensitive string matching:
- {'fpath' : {'$icase' : 'val1'}} //icase matching
Ignore case matching with '$in' operation:
- {'name' : {'$icase' : {'$in' : ['tHéâtre - театр', 'heLLo WorlD']}}}
For case insensitive matching you can create special type of string index.
- $elemMatch The $elemMatch operator matches more than one component within an array element.
- { array: { $elemMatch: { value1 : 1, value2 : { $gt: 1 } } } }
Restriction: only one $elemMatch allowed in context of one array field.
- Queries can be used to update records:
$set Field set operation.
- {.., '$set' : {'field1' : val1, 'fieldN' : valN}}
$upsert Atomic upsert. If matching records are found it will be '$set' operation,
otherwise new record will be inserted with fields specified by argment object.
- {.., '$upsert' : {'field1' : val1, 'fieldN' : valN}}
$inc Increment operation. Only number types are supported.
- {.., '$inc' : {'field1' : number, ..., 'field1' : number}
$dropall In-place record removal operation.
- {.., '$dropall' : true}
$addToSet Atomically adds value to the array only if its not in the array already.
If containing array is missing it will be created.
- {.., '$addToSet' : {'fpath' : val1, 'fpathN' : valN, ...}}
$addToSetAll Batch version if $addToSet
- {.., '$addToSetAll' : {'fpath' : [array of values to add], ...}}
$pull Atomically removes all occurrences of value from field, if field is an array.
- {.., '$pull' : {'fpath' : val1, 'fpathN' : valN, ...}}
$pullAll Batch version of $pull
- {.., '$pullAll' : {'fpath' : [array of values to remove], ...}}
NOTE: It is better to execute update queries with `$onlycount=true` hint flag
or use the special `update()` method to avoid unnecessarily rows fetching.
NOTE: Negate operations: $not and $nin not using indexes
so they can be slow in comparison to other matching operations.
NOTE: Only one index can be used in search query operation.
NOTE: If callback is not provided this function will be synchronous.
QUERY HINTS (specified by `hints` argument):
- $max Maximum number in the result set
- $skip Number of skipped results in the result set
- $orderby Sorting order of query fields.
- $onlycount true|false If `true` only count of matching records will be returned
without placing records in result set.
- $fields Set subset of fetched fields
If a field presented in $orderby clause it will be forced to include in resulting records.
Example:
hints: {
"$orderby" : { //ORDER BY field1 ASC, field2 DESC
"field1" : 1,
"field2" : -1
},
"$fields" : { //SELECT ONLY {_id, field1, field2}
"field1" : 1,
"field2" : 1
}
}
Many C API query examples can be found in `tcejdb/testejdb/t2.c` test case.
To traverse selected records cursor object is used:
- Cursor#next() Move cursor to the next record and returns true if next record exists.
- Cursor#hasNext() Returns true if cursor can be placed to the next record.
- Cursor#field(name) Retrieve value of the specified field of the current JSON object record.
- Cursor#object() Retrieve whole JSON object with all fields.
- Cursor#reset() Reset cursor to its initial state.
- Cursor#length Read-only property: Number of records placed into cursor.
- Cursor#pos Read/Write property: You can set cursor position: 0 <= pos < length
- Cursor#close() Closes cursor and free cursor resources. Cursor cant be used in closed state.
