Field Details

NO_OP_CONTEXT_MAP

private static final String NO_OP_CONTEXT_MAP

Constant used to disable the ThreadContextMap.

Warning: the value of this constant does not point to a concrete class name.

See Also:

• Provider.getThreadContextMap()
• Constant Field Values

WEB_APP_CONTEXT_MAP

private static final String WEB_APP_CONTEXT_MAP

Constant used to select a web application-safe implementation of ThreadContextMap.

This implementation only binds JRE classes to ThreadLocal variables.

Warning: the value of this constant does not point to a concrete class name.

See Also:

• Provider.getThreadContextMap()
• Constant Field Values

GARBAGE_FREE_CONTEXT_MAP

private static final String GARBAGE_FREE_CONTEXT_MAP

Constant used to select a garbage-free implementation of ThreadContextMap.

This implementation must ensure that common operations don't create new object instances. The drawback is the necessity to bind custom classes to ThreadLocal variables.

Warning: the value of this constant does not point to a concrete class name.

• Provider.getThreadContextMap()
• Constant Field Values
