Type Members

  1. trait AsyncExecutor extends Closeable

    A connection pool for asynchronous execution of blocking I/O actions.

    A connection pool for asynchronous execution of blocking I/O actions. This is used for the asynchronous query execution API on top of blocking back-ends like JDBC.

  2. trait AsyncExecutorMXBean extends AnyRef

    The information that is exposed by an AsyncExecutor via JMX.

  3. trait CloseableIterator[+T] extends Iterator[T] with Closeable

    An Iterator with a close method to close the underlying data source.

    An Iterator with a close method to close the underlying data source. Implementers must close the data source when hasNext returns false.

  4. final class ConfigExtensionMethods extends AnyVal

    Extension methods to make Typesafe Config easier to use

  5. final class ConstArray[+T] extends Product

    An efficient immutable array implementation which is used in the AST.

    An efficient immutable array implementation which is used in the AST. Semantics are generally the same as for Scala collections but for performance reasons it does not implement any standard collection traits.

  6. final class ConstArrayBuilder[T] extends AnyRef

    A mutable builder for ConstArrays.

  7. trait ConstArrayOp[+T] extends Any

    A lazy operation on a ConstArray, produced by withFilter, zip, zipWithIndex and ConstArrayOp.from(Range).

  8. case class DumpInfo(name: String, mainInfo: String = "", attrInfo: String = "", children: Iterable[(String, Dumpable)] = Vector.empty) extends Product with Serializable

    The information required for dumping a single object

  9. trait Dumpable extends AnyRef

    Interface for types that can be used in a tree dump

  10. trait Logging extends AnyRef
  11. class MacroSupportInterpolation extends AnyRef
  12. class ManagedArrayBlockingQueue[E >: Null <: PrioritizedRunnable] extends AbstractQueue[E] with BlockingQueue[E] with Logging

    A simplified copy of java.util.concurrent.ArrayBlockingQueue with additional logic for temporarily rejecting elements based on the current size.

    A simplified copy of java.util.concurrent.ArrayBlockingQueue with additional logic for temporarily rejecting elements based on the current size. All features of the original ArrayBlockingQueue have been ported, except the mutation methods of the iterator. See java.util.concurrent.ArrayBlockingQueue for documentation.

    Furthermore this implementation has a pause feature where it does not pass through low- or mid-priority tasks when paused.

  13. final class ProductWrapper extends Product

    A Product to represent larger arities than Tuple22

  14. final class RangeConstArrayOp extends ConstArrayOp[Int]
  15. trait ReadAheadIterator[+T] extends BufferedIterator[T]

    An iterator on top of a data source which does not offer a hasNext() method without doing a next()

  16. final case class RefId[E <: AnyRef](e: E) extends Product with Serializable

    A wrapper for a value, which uses reference equality of the wrapped value as its own equality.

    A wrapper for a value, which uses reference equality of the wrapped value as its own equality. This can be used, for example, to get the equivalent of an IdentityHashMap from a regular HashMap.

  17. final class SQLBuilder extends AnyRef
  18. final class SlickLogger extends AnyRef
  19. class TableDump extends AnyRef

    Utility methods for creating result set debug output.

  20. case class TreePrinter(name: String = "", prefix: String = "", firstPrefix: String = null, narrow: (Dumpable) => Dumpable = identity, mark: (Dumpable) => Boolean = _ => false) extends Product with Serializable

    Create a readable printout of a tree.

Value Members

  1. def ??: Nothing

    Throw an UnsupportedOperationException.

    Throw an UnsupportedOperationException. Like ??? but NonFatal.

  2. val ignoreFollowOnError: PartialFunction[Throwable, Unit]

    An exception handler which ignores NonFatal exceptions.

    An exception handler which ignores NonFatal exceptions. It is used when running cleanup code inside of another exception handler to prevent an exception during cleanup from overriding the original one.

  3. object AsyncExecutor extends Logging
  4. object BeanConfigurator extends Logging

    Configure Java Beans reflectively, using Typesafe Config for data type conversions.

  5. object ClassLoaderUtil

    Utilities for working with classloaders

  6. object CloseableIterator
  7. object ConfigExtensionMethods
  8. object ConstArray
  9. object ConstArrayOp
  10. object DumpInfo extends Serializable
  11. object Ellipsis

    Create a wrapper for a Dumpable to omit some nodes.

  12. object GlobalConfig

    Singleton object with Slick's configuration, loaded from the application config.

    Singleton object with Slick's configuration, loaded from the application config. This includes configuration for the global profile objects and settings for debug logging.

    In addition to being listed in reference.conf, all essential config options also have their default values hardcoded here because we cannot rely on getting reference.conf on the classpath in all cases (e.g. the tsql macro).

  13. object MacroSupport
  14. object ReadAheadIterator
  15. object SQLBuilder
  16. object SlickLogger
  17. object TreePrinter extends Serializable
  18. object TupleMethods

    Extension methods for prepending and appending values to tuples

  19. object TupleSupport

    Utility functions for working with tuples of different arities
