condition-spec

Collection of value classes that can be used for search in abstract data source. See the list of classes in Dokka

Usage

dependencies {
    implementation("com.github.nikita715.condition-spec:condition-spec-base:1.0.5")
}

Code example

interface UserService {

    fun findOneBy(
        id: SingleCondition<Long>? = null,
        firstName: Condition<String>? = null,
        lastName: Condition<String>? = null,
        birthDate: RangeCondition<LocalDateTime>? = null,
    ): UserModel?

}

userService.findOneBy(
    firstName = Eq("Bill"),
    lastName = NotIn("Stivenson", "Jackson") and Like("son"),
    birthDate = LessEq(LocalDateTime.now().minusYears(21)),
)

Exposed adapter

Adapter that translates condition-spec conditions to Exposed search conditions

Usage

dependencies {
    implementation("com.github.nikita715.condition-spec:condition-spec-base:1.0.5")
    implementation("com.github.nikita715.condition-spec:condition-spec-exposed-adapter:1.0.5")
}

Code example

class UserServiceImpl: UserService {
    override fun findOneBy(
        id: SingleCondition<Long>?,
        firstName: Condition<String>?,
        lastName: Condition<String>?,
        birthDate: RangeCondition<LocalDateTime>?,
    ): UserModel? =
        UserTable.select {
            listOfNotNull(
                UserTable.id matches id,
                UserTable.firstName matches firstName,
                UserTable.lastName matches lastName,
                UserTable.birthDate matches birthDate,
            ).compoundAnd()
        }.limit(1).firstOrNull()?.toUserModel()

    ...
