com.google.inject.internal.InternalProvisionException

All Implemented Interfaces:

Serializable

public final class InternalProvisionException
extends Exception

A checked exception for provisioning errors.

This is the internal dual of ProvisionException, similar to the relationship between ConfigurationException and ErrorsException. This is useful for several reasons:

• Since it is a checked exception, we get some assistance from the java compiler in ensuring that we correctly handle it everywhere. ProvisionException is unchecked.
• Since this is an internal package, we can add useful construction and mutation APIs that would be undesirable in a public supported API.

This exception will be thrown when errors are encountered during provisioning, ErrorsException will continue to be used for errors that are encountered during provisioning and both make use of the Message as the core model.

NOTE: this object stores a list of messages but in the most common case the cardinality will be 1. The only time that multiple errors might be reported via this mechanism is when errorInUserCode(java.lang.Throwable, java.lang.String, java.lang.Object...) is called with an exception that holds multiple errors (like ProvisionException).

 Dependency<?> dependency)
                                             throws InternalProvisionException

Returns value if it is non-null or allowed to be null. Otherwise a message is added and an InternalProvisionException is thrown.

Throws:

InternalProvisionException

addSource

InternalProvisionException addSource(Object source)

Prepends the given source to the stack of binding sources for the errors reported in this exception.

See Errors.withSource(Object)

It is expected that this method is called as the exception propagates up the stack.

Parameters:

source -

Returns:

this

getErrors

com.google.common.collect.ImmutableList<Message> getErrors()

toProvisionException

public ProvisionException toProvisionException()

Returns this exception convered to a ProvisionException.
