syncReadOptional

public <T extends org.opendaylight.yangtools.yang.binding.DataObject> com.google.common.base.Optional<T> syncReadOptional(org.opendaylight.controller.md.sal.common.api.data.LogicalDatastoreType datastoreType,
                                                                                                                          org.opendaylight.yangtools.yang.binding.InstanceIdentifier<T> path)

Synchronously read; preferred & strongly recommended method variant over other ones offered by this class (because this is the most explicit variant).

See ReadTransaction.read(LogicalDatastoreType, InstanceIdentifier).

Type Parameters:

T - DataObject subclass

Parameters:

datastoreType - Logical data store from which read should occur.

path - Path which uniquely identifies subtree which client want to read

Returns:

If the data at the supplied path exists, returns an Optional object containing the data; if the data at the supplied path does not exist, returns Optional#absent().

Throws:

org.opendaylight.controller.md.sal.common.api.data.ReadFailedException - in case of a technical (!) error while reading

syncReadOptional

public static <T extends org.opendaylight.yangtools.yang.binding.DataObject> com.google.common.base.Optional<T> syncReadOptional(org.opendaylight.controller.md.sal.binding.api.DataBroker broker,
                                                                                                                                 org.opendaylight.controller.md.sal.common.api.data.LogicalDatastoreType datastoreType,
                                                                                                                                 org.opendaylight.yangtools.yang.binding.InstanceIdentifier<T> path)

Throws:

org.opendaylight.controller.md.sal.common.api.data.ReadFailedException

syncRead

public <T extends org.opendaylight.yangtools.yang.binding.DataObject> T syncRead(org.opendaylight.controller.md.sal.common.api.data.LogicalDatastoreType datastoreType,
                                                                                 org.opendaylight.yangtools.yang.binding.InstanceIdentifier<T> path)
                                                                          throws org.opendaylight.controller.md.sal.common.api.data.ReadFailedException

Synchronously read; method variant to use by code which expecting that data MUST exist at given path.

This variant is only recommended if the calling code would treat the Optional returned by the other method variant as a terminal failure anyway, and would itself throw an Exception for that.

If calling code can more sensibly handle non-present data, then use syncReadOptional(LogicalDatastoreType, InstanceIdentifier) instead of this.

See ReadTransaction.read(LogicalDatastoreType, InstanceIdentifier).

Type Parameters:

T - DataObject subclass

Parameters:

datastoreType - Logical data store from which read should occur.

path - Path which uniquely identifies subtree which client want to read

Returns:

If the data at the supplied path exists, returns the data.

Throws:

org.opendaylight.controller.md.sal.common.api.data.ReadFailedException - in case of a technical (!) error while reading

ExpectedDataObjectNotFoundException - a ReadFailedException sub-type, if no data exists at path

Deprecated. This variant is not recommended, and only exists for legacy purposes for code which does not yet correctly propagate technical exceptions. Prefer using syncReadOptional(LogicalDatastoreType, InstanceIdentifier).

Synchronously read; swallowing (!) ReadFailedException.

See ReadTransaction.read(LogicalDatastoreType, InstanceIdentifier).

Type Parameters:

T - DataObject subclass

Parameters:

datastoreType - Logical data store from which read should occur.

path - Path which uniquely identifies subtree which client want to read

Returns:

If the data at the supplied path exists, returns an Optional object containing the data; if the data at the supplied path does not exist, or a technical error occurred (logged), returns Optional#absent().
