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 strictly equal to the provided value.
{
<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' }
}
