Method Detail

acquire

public <T extends ConnectionContext> T acquire(@NotNull
                                               java.lang.Class<T> contextClass)

Description copied from interface: ConnectionContextService

Acquire a connection context. Depending on the implementation, this may return a context from a pool or create a new instance.

Specified by:

acquire in interface ConnectionContextService

Type Parameters:

T - the type of connection context

Parameters:

contextClass - the class type of the connection context to acquire

Returns:

a connection context ready for use

acquire

public <T extends ConnectionContext> T acquire(@NotNull
                                               java.lang.Class<T> contextClass,
                                               @Nullable java.util.function.Consumer<T> initializer)

Description copied from interface: ConnectionContextService

Acquire a connection context with optional initialization. Depending on the implementation, this may return a context from a pool or create a new instance. The initializer is invoked on the context before returning it.

Specified by:

acquire in interface ConnectionContextService

Type Parameters:

T - the type of connection context

Parameters:

contextClass - the class type of the connection context to acquire

initializer - optional consumer to initialize the context before use; may be null

Returns:

a connection context ready for use

release

public boolean release(ConnectionContext context)

Description copied from interface: ConnectionContextService

Release a connection context. For pooled implementations, the context is reset and made available for subsequent acquire operations. For non-pooled implementations, the context may simply be marked as inactive.

Specified by:

release in interface ConnectionContextService

Parameters:

context - the context to release

Returns:

true if the context was successfully released, false otherwise

clear

public static void clear()
