## com.trolltech.qt.core
Class QSystemSemaphore.AccessMode

    java.lang.Object
      java.lang.Enum
          com.trolltech.qt.core.QSystemSemaphore.AccessMode

All Implemented Interfaces:
  QtEnumerator, java.io.Serializable, java.lang.Comparable

Enclosing class:
  QSystemSemaphore

    public static final class QSystemSemaphore.AccessMode

extends java.lang.Enum
implements QtEnumerator

This enum is used by the constructor and `setKey()`. Its purpose is to enable handling the problem in Unix implementations of semaphores that survive a crash. In Unix, when a semaphore survives a crash, we need a way to force it to reset its resource count, when the system reuses the semaphore. In Windows, where semaphores can't survive a crash, this enum has no effect.

Field Summary
`static QSystemSemaphore.AccessMode` | `Create` `QSystemSemaphore` takes ownership of the semaphore and sets its resource count to the requested value, regardless of whether the semaphore already exists by having survived a crash.
`static QSystemSemaphore.AccessMode` | `Open` If the semaphore already exists, its initial resource count is not reset.

Method Summary
`static QSystemSemaphore.AccessMode` | `resolve(int value)` Returns the AccessMode constant with the specified `int`.
`int` | `value()` This function should return an integer value for the enum values of the enumeration that implements this interface.
`static QSystemSemaphore.AccessMode` | `valueOf(java.lang.String name)`
`static QSystemSemaphore.AccessMode[]` | `values()`

Field Detail

### Open

    public static final QSystemSemaphore.AccessMode Open

  If the semaphore already exists, its initial resource count is not reset. If the semaphore does not already exist, it is created and its initial resource count set.

### Create

    public static final QSystemSemaphore.AccessMode Create

  `QSystemSemaphore` takes ownership of the semaphore and sets its resource count to the requested value, regardless of whether the semaphore already exists by having survived a crash. This value should be passed to the constructor, when the first semaphore for a particular key is constructed and you know that if the semaphore already exists it could only be because of a crash. In Windows, where a semaphore can't survive a crash, Create and Open have the same behavior.

Method Detail

### values

    public static QSystemSemaphore.AccessMode[] values()

### valueOf

    public static QSystemSemaphore.AccessMode valueOf(java.lang.String name)

### value

    public int value()

  This function should return an integer value for the enum values of the enumeration that implements this interface.

  Specified by:
    `value` in interface `QtEnumerator`

### resolve

    public static QSystemSemaphore.AccessMode resolve(int value)

  Returns the AccessMode constant with the specified `int`.
