PooledContextSource (Spring LDAP 2.2.0.RELEASE API)

java.lang.Object
- org.springframework.ldap.core.support.DelegatingBaseLdapPathContextSourceSupport
- - org.springframework.ldap.pool2.factory.PooledContextSource

All Implemented Interfaces:: DisposableBean, ContextSource, BaseLdapPathSource

Direct Known Subclasses:: MutablePooledContextSource

public class PooledContextSource
extends DelegatingBaseLdapPathContextSourceSupport
implements ContextSource, DisposableBean

A ContextSource implementation that wraps an object pool and another ContextSource. DirContexts are retrieved from the pool which maintains them. NOTE: This implementation is based on apache commons-pool2.

Configuration:

Property	Description	Required	Default
contextSource	The `ContextSource` to get `DirContext`s from for adding to the pool.	Yes	null
dirContextValidator	The `DirContextValidator` to use for validating `DirContext`s. Required if any of the test/validate options are enabled.	No	null
poolConfig	The `PoolConfig` to configure the pool.	No	null

Since:: 2.0
Author:: Eric Dalquist, Anindya Chatterjee

    Parameters:

  - setDirContextValidator
```
public void setDirContextValidator(DirContextValidator dirContextValidator)
```
    Parameters:
    
    dirContextValidator - the dirContextValidator to set Required
  - setNonTransientExceptions
```
public void setNonTransientExceptions(Collection<Class<? extends Throwable>> nonTransientExceptions)
```
    Configure the exception classes that are to be interpreted as no-transient with regards to eager context invalidation. If one of the configured exceptions (or subclasses of them) is thrown by any method on a pooled DirContext, that instance will immediately be marked as invalid without any additional testing (i.e. testOnReturn). This allows for more efficient management of dead connections. Default is CommunicationException.
    
    Parameters:
    
    nonTransientExceptions - the exception classes that should be interpreted as non-transient with regards to eager invalidation.

  - destroy
```
public void destroy()
             throws Exception
```
    Specified by:
    
    destroy in interface DisposableBean
    
    Throws:
    
    Exception
  - getTarget
```
protected ContextSource getTarget()
```
    Description copied from class: DelegatingBaseLdapPathContextSourceSupport
    
    Get the target ContextSource.
    
    Specified by:
    
    getTarget in class DelegatingBaseLdapPathContextSourceSupport
    
    Returns:
    
    the target ContextSource.
  - getReadOnlyContext
```
public DirContext getReadOnlyContext()
```
    Description copied from interface: ContextSource
    
    Gets a read-only DirContext. The returned DirContext must be possible to perform read-only operations on.
    
    Specified by:
    
    getReadOnlyContext in interface ContextSource
    
    Returns:
    
    A DirContext instance, never null.
  - getReadWriteContext
```
public DirContext getReadWriteContext()
```
    Description copied from interface: ContextSource
    
    Gets a read-write DirContext instance.
    
    Specified by:
    
    getReadWriteContext in interface ContextSource
    
    Returns:
    
    A DirContext instance, never null.
  - getContext
```
protected DirContext getContext(DirContextType dirContextType)
```
    Gets a DirContext of the specified type from the keyed object pool.
    
    Parameters:
    
    dirContextType - The type of context to return.
    
    Returns:
    
    A wrapped DirContext of the specified type.
    
    Throws:
    
    DataAccessResourceFailureException - If retrieving the object from the pool throws an exception
  - getContext
```
public DirContext getContext(String principal,
                             String credentials)
```
    Description copied from interface: ContextSource
    
    Gets a DirContext instance authenticated using the supplied principal and credentials. Typically to be used for plain authentication purposes. Note that this method will never make use of native Java LDAP pooling, even though this instance is configured to do so. This is to force password changes in the target directory to take effect as soon as possible.
    
    Specified by:
    
    getContext in interface ContextSource
    
    Parameters:
    
    principal - The principal (typically a distinguished name of a user in the LDAP tree) to use for authentication.
    
    credentials - The credentials to use for authentication.
    
    Returns:
    
    an authenticated DirContext instance, never null.
