bitsAllClear¶

abstract fun bitsAllClear(mask: ERROR CLASS: Symbol not found for UInt)

Matches documents where all bit positions present in mask are clear (i.e., 0) in the current field.

This operator will not match numerical values that cannot be represented as a signed 64-bit integer (e.g. Decimal128) nor ones that have a fractional component.

Example¶

class User(
    val name: String,
    val age: Int?,
)

collection.find {
    User::age {
        bitsAllClear(UInt.MAX_VALUE)
    }
}

Performance¶

Queries cannot use indexes for this operator, but they can use indexes for other operators.
