specific, immutable, thread-safe instance of the context

Method Summary

Modifier and Type	Method and Description
void	clearInstanceInvocation() remove cached invocation from this instance, in case the underlying app unloaded but component ID remains, just in case the app is reloaded
String	getInstanceComponentId()
boolean	isEmpty()
boolean	isLoaded() This is different from class loaded, as there are some situations where class is loaded but initialization is not complete, such as CDI initializations, extensions start, etc.
ContextProducer.Context	pushContext() pushes Java EE invocation context onto the invocation stack use try-with-resources to pop the context no-op if non-running context
ContextProducer.Context	pushRequestContext() pushes invocation context onto the stack Also creates Request scope use try-with-resources to pop the context no-op if non-running context
ContextProducer.Context	setApplicationClassLoader() set context class loader by component id of this instance for empty or unloaded component, class loader remains unset and the context is a no-op (no re-set gets done) so it's a no-op

Method Detail

pushContext

ContextProducer.Context pushContext()

pushes Java EE invocation context onto the invocation stack use try-with-resources to pop the context no-op if non-running context

Returns:

the new context that was created

pushRequestContext

ContextProducer.Context pushRequestContext()

pushes invocation context onto the stack Also creates Request scope use try-with-resources to pop the context no-op if non-running context

Returns:

new context that was created

setApplicationClassLoader

ContextProducer.Context setApplicationClassLoader()

set context class loader by component id of this instance for empty or unloaded component, class loader remains unset and the context is a no-op (no re-set gets done) so it's a no-op

Returns:

context so class loader can be reset

getInstanceComponentId

String getInstanceComponentId()

Returns:

component ID for the current instance, or null if empty instance

isLoaded

boolean isLoaded()

This is different from class loaded, as there are some situations where class is loaded but initialization is not complete, such as CDI initializations, extensions start, etc.

Returns:

true if component is loaded and starting

isEmpty

boolean isEmpty()

Returns:

true if this is an empty context

clearInstanceInvocation

void clearInstanceInvocation()

remove cached invocation from this instance, in case the underlying app unloaded but component ID remains, just in case the app is reloaded
