Class CursorConfig

    java.lang.Object
      com.sleepycat.db.CursorConfig

All Implemented Interfaces:
  Cloneable

    public class CursorConfig

extends Object
implements Cloneable

Specify the attributes of database cursor. An instance created with the default constructor is initialized with the system's default settings.

Field Summary
`static CursorConfig` | `DEFAULT` Default configuration used if null is passed to methods that create a cursor.
`static CursorConfig` | `DEGREE_2` Deprecated. This has been replaced by `READ_COMMITTED` to conform to ANSI database isolation terminology.
`static CursorConfig` | `DIRTY_READ` Deprecated. This has been replaced by `READ_UNCOMMITTED` to conform to ANSI database isolation terminology.
`static CursorConfig` | `READ_COMMITTED` A convenience instance to configure a cursor for read committed isolation.
`static CursorConfig` | `READ_UNCOMMITTED` A convenience instance to configure read operations performed by the cursor to return modified but not yet committed data.
`static CursorConfig` | `WRITECURSOR` A convenience instance to specify the Concurrent Data Store environment cursor will be used to update the database.

Constructor Summary
`CursorConfig()` An instance created using the default constructor is initialized with the system's default settings.

Method Summary
`boolean` | `getDegree2()` Deprecated. This has been replaced by `getReadCommitted()` to conform to ANSI database isolation terminology.
`boolean` | `getDirtyRead()` Deprecated. This has been replaced by `getReadUncommitted()` to conform to ANSI database isolation terminology.
`boolean` | `getReadCommitted()` Return if the cursor is configured for read committed isolation.
`boolean` | `getReadUncommitted()` Return if read operations performed by the cursor are configured to return modified but not yet committed data.
`boolean` | `getWriteCursor()` Return if the Concurrent Data Store environment cursor will be used to update the database.
`void` | `setDegree2(boolean degree2)` Deprecated. This has been replaced by `setReadCommitted(boolean)` to conform to ANSI database isolation terminology.
`void` | `setDirtyRead(boolean dirtyRead)` Deprecated. This has been replaced by `setReadUncommitted(boolean)` to conform to ANSI database isolation terminology.
`void` | `setReadCommitted(boolean readCommitted)` Configure the cursor for read committed isolation.
`void` | `setReadUncommitted(boolean readUncommitted)` Configure read operations performed by the cursor to return modified but not yet committed data.
`void` | `setWriteCursor(boolean writeCursor)` Specify the Concurrent Data Store environment cursor will be used to update the database.

Field Detail

### DEFAULT

    public static final CursorConfig DEFAULT

  Default configuration used if null is passed to methods that create a cursor.

### READ_UNCOMMITTED

    public static final CursorConfig READ_UNCOMMITTED

  A convenience instance to configure read operations performed by the cursor to return modified but not yet committed data.

### DIRTY_READ

    public static final CursorConfig DIRTY_READ

  Deprecated. This has been replaced by `READ_UNCOMMITTED` to conform to ANSI database isolation terminology.
  A convenience instance to configure read operations performed by the cursor to return modified but not yet committed data.

### READ_COMMITTED

    public static final CursorConfig READ_COMMITTED

  A convenience instance to configure a cursor for read committed isolation.

  This ensures the stability of the current data item read by the cursor but permits data read by this cursor to be modified or deleted prior to the commit of the transaction.

### DEGREE_2

    public static final CursorConfig DEGREE_2

  Deprecated. This has been replaced by `READ_COMMITTED` to conform to ANSI database isolation terminology.
  A convenience instance to configure a cursor for read committed isolation.

  This ensures the stability of the current data item read by the cursor but permits data read by this cursor to be modified or deleted prior to the commit of the transaction.

### WRITECURSOR

    public static final CursorConfig WRITECURSOR

  A convenience instance to specify the Concurrent Data Store environment cursor will be used to update the database.

  The underlying Berkeley DB database environment must have been configured as a Concurrent Data Store environment.

Constructor Detail

### CursorConfig

    public CursorConfig()

  An instance created using the default constructor is initialized with the system's default settings.

Method Detail

### setReadUncommitted

    public void setReadUncommitted(boolean readUncommitted)

  Configure read operations performed by the cursor to return modified but not yet committed data.

  Parameters:
    `readUncommitted` - If true, configure read operations performed by the cursor to return modified but not yet committed data.

### getReadUncommitted

    public boolean getReadUncommitted()

  Return if read operations performed by the cursor are configured to return modified but not yet committed data.

  Returns:
    If read operations performed by the cursor are configured to return modified but not yet committed data.

### setDirtyRead

    public void setDirtyRead(boolean dirtyRead)

  Deprecated. This has been replaced by `setReadUncommitted(boolean)` to conform to ANSI database isolation terminology.

  Configure read operations performed by the cursor to return modified but not yet committed data.

  Parameters:
    `dirtyRead` - If true, configure read operations performed by the cursor to return modified but not yet committed data.

### getDirtyRead

    public boolean getDirtyRead()

  Deprecated. This has been replaced by `getReadUncommitted()` to conform to ANSI database isolation terminology.

  Return if read operations performed by the cursor are configured to return modified but not yet committed data.

  Returns:
    If read operations performed by the cursor are configured to return modified but not yet committed data.

### setReadCommitted

    public void setReadCommitted(boolean readCommitted)

  Configure the cursor for read committed isolation.

  This ensures the stability of the current data item read by the cursor but permits data read by this cursor to be modified or deleted prior to the commit of the transaction.

  Parameters:
    `readCommitted` - If true, configure the cursor for read committed isolation.

### getReadCommitted

    public boolean getReadCommitted()
