Class DataSchemaContextTree

java.lang.Object

org.opendaylight.yangtools.yang.data.util.DataSchemaContextTree

public final class DataSchemaContextTree
extends Object

Semantic tree binding a EffectiveModelContext to a NormalizedNode tree. Since the layout of the schema and data has differences, the mapping is not trivial -- which is where this class comes in.

from

public static @NonNull DataSchemaContextTree from(@NonNull EffectiveModelContext ctx)

modelContext

public @NonNull EffectiveModelContext modelContext()

Return the EffectiveModelContext used to derive this tree.

Returns:

the EffectiveModelContext used to derive this tree

childByPath

public @Nullable DataSchemaContext childByPath(@NonNull YangInstanceIdentifier path)

Find a child node as identified by an absolute YangInstanceIdentifier.

Parameters:

path - Path towards the child node

Returns:

Child node if present, or null when corresponding child is not found.

Throws:

NullPointerException - if path is null

findChild

public @NonNull Optional<@NonNull DataSchemaContext> findChild(@NonNull YangInstanceIdentifier path)

Find a child node as identified by an absolute YangInstanceIdentifier.

Parameters:

path - Path towards the child node

Returns:

Child node if present, or empty when corresponding child is not found.

Throws:

NullPointerException - if path is null

enterPath

public @NonNull CheckedValue<@NonNull DataSchemaContextTree.NodeAndStack,@NonNull IllegalArgumentException> enterPath(YangInstanceIdentifier path)

Find a child node as identified by an absolute YangInstanceIdentifier and return it along with a suitably initialized SchemaInferenceStack.

Parameters:

path - Path towards the child node

Returns:

A DataSchemaContextTree.NodeAndStack, or empty when corresponding child is not found.

Throws:

NullPointerException - if path is null

getRoot

public @NonNull DataSchemaContext.Composite getRoot()
