matchesWhereQuery( object, whereQuery )

This function determines if the provided object matches every comparison clause in whereQuery, returning true or false accordingly.

whereQuery is an object of the form:

{
	<attribute> : <value>
	<attribute> : [ <value1>, ..., <valueN> ]
	<attribute> : { comparator : <comparator> }
	<attribute> : { comparator : <comparator>, value : <value> }
}

Comparisons

For each clause in whereQuery, an attribute of object is compared to a value (primitive or object.) except in the cases of the isNull and isNotNull comparators, which do not require for a value to be provided.

equals (default)

Single Value

If the attribute is a single value, object.attribute must strictly equal the value to result in a match.

{
	<attribute> : <value>
}

Array

If the attribute is is an array, only records for which object.attribute is strictly equally to one of the elements in the array will result in a match.

{
	<attribute> : [ <value1>, ..., <valueN> ]
}

contains

The compared attribute must be a string that contains the provided value, or an array that has at least one element equal to the provided value. In case the attribute is an array, uses _.isEqual to perform an optimized deep comparison between the array items and the provided value, to determine if they should be considered equal, allowing to match objects in arrays of objects.

{
   <attribute> : { comparator : 'contains', value : <value> }
}

doesNotEqual

The compared attribute must must not be strictly equal to the value to result in a match.

{
	<attribute> : { comparator : 'doesNotEqual', value : <value> }
}

isGreaterThan

The compared attribute must be greater than the value to result in a match. NULL values are automatically discarded.

{
	<attribute> : { comparator : 'isGreaterThan', value : <value> }
}

isGreaterThanOrEqualTo

The compared attribute must be greater than or equal to the value to result in a match. NULL values are automatically discarded.

{
	<attribute> : { comparator : 'isGreaterThan', value : <value> }
}

isLessThan

The compared attribute must be less than the value to result in a match. NULL values are automatically discarded.

{
	<attribute> : { comparator : 'isLessThan', value : <value> }
}

isLessThanOrEqualTo

The compared attribute must be less than or equal to the value to result in a match. NULL values are automatically discarded.

{
	<attribute> : { comparator : 'isLessThanOrEqualTo', value : <value> }
}

isBetween

The compared attribute must be between the minimum and maximum values provided to result in a match. The limits provided are included in the range for the value. NULL values are automatically discarded.

{
	<attribute> : { comparator : 'isBetween', value : [ <minValue>, <maxValue> ] }
}

startsWith

The compared attribute must be a string that starts with the string value provided to result in a match. NULL values are automatically discarded.

{
	<attribute> : { comparator : 'startsWith', value : <value> }
}

endsWith

The compared attribute must be a string that ends with the string value provided to result in a match. NULL values are automatically discarded.

{
	<attribute> : { comparator : 'endsWith', value : <value> }
}

isNull

The compared attribute must be null to result in a match (no value needs to be provided).

{
	<attribute> : { comparator : 'isNull' }
}

isNotNull

The compared attribute must not be null to result in a match (no value needs to be provided).

{
	<attribute> : { comparator : 'isNotNull' }
}
