bitsAllClear¶

abstract fun bitsAllClear(mask: )

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.
