Enum Constant Detail

• KEY_VALUE

  public static final SessionMode KEY_VALUE

  Key/value database mode.

  This is the lowest level CLI mode, where only the raw byte[] key/value store is available. This mode provides a KVTransaction, but no Transaction or JTransaction.

  See Also:

  org.jsimpledb.kv

• CORE_API

  public static final SessionMode CORE_API

  Core API mode.

  Supports access to low level schema information, core API "objects" and fields, but no Java-specific operations. This mode provides a KVTransaction and Transaction, but no JTransaction.

  Schema information may be provided either by a schema XML file or by @JSimpleClass-annotated Java model classes; however, in the latter case these classes will be otherwise ignored.

  In this mode, database objects are represented by ObjId's and enum values by EnumValue's.

• JSIMPLEDB

  public static final SessionMode JSIMPLEDB

  JSimpleDB (or "Java") mode.

  Provides i.e., when the there are no @JSimpleClass-annotated Java model classes defined and the core Database API is used.

  In this mode, database objects are represented by Java model class instances and enum values by corresponding Java model Enum class instances.

Method Detail

• values

  public static SessionMode[] values()

  Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

  for (SessionMode c : SessionMode.values())
      System.out.println(c);
  

  Returns:

  an array containing the constants of this enum type, in the order they are declared

• valueOf

  public static SessionMode valueOf(String name)

  Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

  Parameters:

  name - the name of the enum constant to be returned.

  Returns:

  the enum constant with the specified name

  Throws:

  IllegalArgumentException - if this enum type has no constant with the specified name

  NullPointerException - if the argument is null

• hasJSimpleDB

  public boolean hasJSimpleDB()

  Determine whether the JSimpleDB (or "Java") API (e.g., JTransaction) is available in this mode.

  Returns:

  true if the JSimpleDB "Java" API is available

• hasCoreAPI

  public boolean hasCoreAPI()

  Determine whether the core API (e.g., Transaction) is available in this mode.

  Returns:

  true if the core API is available
