Methods

Name Description Return Type SDK
PopulateManifestRelationshipsAsync(CdmRelationshipDiscoveryStyle)
option [optional]: The type of relationships we want populated in the manifest.

populate_entity_relationships() in Python.
Populates the relationships that the entities in the current manifest are involved in. This function is used to pre-calculate relationships that lead to optimizations during the resolution process. Task 1.0
CreateResolvedManifestAsync(string, string, ResolveOptions)
newManifestName: The corpus path to the name of the new manifest.
newEntityDocumentNameFormat: Specifies the pattern to use when creating documents for resolved entities. The default is "{f}resolved/{n}.cdm.json" to avoid a document name conflict with documents in the same folder as the manifest.
resOpt [optional]: The resolve options.
Creates a resolved copy of the manifest. Every instance of the string {n} from the argument is replaced with the entity name from the source manifest. Every instance of the string {f} is replaced with the folder path from the source manifest to the source entity (if there's one that's possible as a relative location, else nothing). A manifest with all the entities resolved is returned. Task<CdmManifestDefinition> 1.0
FileStatusCheckAsync() Updates the object and its children, if any, with the current time. Note that if there were any changes done on the manifest object prior to this call, and the file has been updated and the last modification timestamps don't match, the manifest will then be reloaded from file causing all prior changes to be lost. Task 1.0
FileStatusCheckAsync(PartitionFileStatusCheckType, CdmIncrementalPartitionType, FileStatusCheckOptions)
partitionFileStatusCheckType [optional]: An enum value that denotes the type of partition objects and partition pattern objects to update. The default value is PartitionFileStatusCheckType.Full.
incrementalType [optional]: An enum value that denotes what type of incremental partition objects and incremental partition pattern objects to update. The default value is CdmIncrementalPartitionType.None.
fileStatusCheckOptions [optional]: A set of options to be used during this call. See FileStatusCheckOptions for more information.
Updates the object and its children, if any, with the current time. PartitionFileStatusCheckType and CdmIncrementalPartitionType allow users to have better control of which data partition or/and data partition pattern updates should be performed. Note that if there were any changes done on the manifest object prior to this call, and the file has been updated and the last modification timestamps don't match, the manifest will then be reloaded from file causing all prior changes to be lost.
