Class AbstractSQLCoreProvider.ColumnFeature<U extends AbstractSQLCoreProvider.SQLUser, T>

java.lang.Object

pro.gravit.launchserver.auth.core.AbstractSQLCoreProvider.ColumnFeature<U,T>

Type Parameters:

U - the concrete AbstractSQLCoreProvider.SQLUser subtype this feature reads into

T - the Java type of the value held in the column

Enclosing class:

AbstractSQLCoreProvider

public static final class AbstractSQLCoreProvider.ColumnFeature<U extends AbstractSQLCoreProvider.SQLUser, T>
extends Object

Describes a single optional column in the user table.

A ColumnFeature is enabled when its columnName is non-null. When disabled, it is silently excluded from every SQL fragment — SELECT column list, UPDATE statements, and ResultSet mapping — with no branching required at the call site.

Instances are registered via AbstractSQLCoreProvider.registerColumnFeature(ColumnFeature) inside AbstractSQLCoreProvider.registerOptionalColumns().

Field Details

columnName

public final String columnName

Name of the database column. null means the feature is disabled — it will be excluded from all SQL and ResultSet access.

Method Details

of

public static <U extends AbstractSQLCoreProvider.SQLUser, T>
AbstractSQLCoreProvider.ColumnFeature<U,T> of(String columnName,
 BiConsumer<U, ResultSet> reader)

Creates an enabled feature backed by a custom reader lambda.

ColumnFeature.of(totpColumn, (user, rs) -> user.totpSecret = rs.getString(totpColumn))

ofString

public static <U extends AbstractSQLCoreProvider.SQLUser>
AbstractSQLCoreProvider.ColumnFeature<U,String> ofString(String columnName,
 Function<ResultSet, String> extractor,
 BiConsumer<U,String> setter)

Convenience factory for columns whose value is a String mapped via ResultSet.getString(String) and stored through a setter.

ColumnFeature.ofString(totpColumn, rs -> rs.getString(totpColumn), (user, val) -> user.totpSecret = val)

isEnabled

public boolean isEnabled()

Returns true when columnName is non-null (feature is active).

read

public void read(AbstractSQLCoreProvider.SQLUser user,
 ResultSet rs)
          throws SQLException

Reads this column from rs into user. Must only be called when isEnabled() is true.

Throws:

SQLException - propagated from ResultSet access
