Class NodeSchemaService

SingletonSerializeAsToken

net.corda.node.services.schema.NodeSchemaService

All Implemented Interfaces:

SchemaService, SerializeAsToken

public class NodeSchemaService
extends SingletonSerializeAsToken
implements SchemaService

Most basic implementation of interface SchemaService.

TODO: support loading schema options from node configuration. TODO: support configuring what schemas are to be selected for persistence. TODO: support plugins for schema version upgrading or custom mapping not supported by original interface QueryableState.

Method Summary

Modifier and Type	Method and Description
PersistentState	generateMappedObject(QueryableState state, MappedSchema schema) Map a state to a class PersistentState for the given schema, either via direct support from the state or via custom logic in this service.
java.util.Map<net.corda.core.schemas.MappedSchema,net.corda.node.services.api.SchemaService.SchemaOptions>	getSchemaOptions() Options configured for this node's schemas. A missing entry for a schema implies all properties are null.
java.lang.Iterable<net.corda.core.schemas.MappedSchema>	selectSchemas(QueryableState state) Given a state, select schemas to map it to that are supported by generateMappedObject and that are configured for this node.

Method Detail

getSchemaOptions

public java.util.Map<net.corda.core.schemas.MappedSchema,net.corda.node.services.api.SchemaService.SchemaOptions> getSchemaOptions()

Options configured for this node's schemas. A missing entry for a schema implies all properties are null.

selectSchemas

public java.lang.Iterable<net.corda.core.schemas.MappedSchema> selectSchemas(QueryableState state)

Given a state, select schemas to map it to that are supported by generateMappedObject and that are configured for this node.

generateMappedObject

public PersistentState generateMappedObject(QueryableState state,
                                            MappedSchema schema)

Map a state to a class PersistentState for the given schema, either via direct support from the state or via custom logic in this service.
