EnvFlags (LmdbJava 0.6.1 API)

java.lang.Object
- java.lang.Enum<EnvFlags>
- - org.lmdbjava.EnvFlags

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<EnvFlags>, MaskedFlag
```
public enum EnvFlags
extends java.lang.Enum<EnvFlags>
implements MaskedFlag
```
Flags for use when opening the Env.

Enum Constant Summary

Enum Constants
Enum Constant and Description
`MDB_FIXEDMAP` Mmap at a fixed address (experimental).
`MDB_MAPASYNC` Use asynchronous msync when `MDB_WRITEMAP` is used.
`MDB_NOLOCK` Don't do any locking, caller must manage their own locks.
`MDB_NOMEMINIT` Don't initialize malloc'd memory before writing to datafile.
`MDB_NOMETASYNC` Don't fsync metapage after commit.
`MDB_NORDAHEAD` Don't do readahead (no effect on Windows).
`MDB_NOSUBDIR` No environment directory.
`MDB_NOSYNC` Don't fsync after commit.
`MDB_NOTLS` Tie reader locktable slots to `Txn` objects instead of to threads.
`MDB_RDONLY_ENV` Read only.
`MDB_WRITEMAP` Use writable mmap.

- Method Detail
  - values
```
public static EnvFlags[] 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 (EnvFlags c : EnvFlags.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static EnvFlags valueOf(java.lang.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:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
  - getMask
```
public int getMask()
```
    Description copied from interface: MaskedFlag
    
    Obtains the integer value for this enum which can be included in a mask.
    
    Specified by:
    
    getMask in interface MaskedFlag
    
    Returns:
    
    the integer value for combination into a mask
