Interface: MetadataProvider

Defined in: data/metadataProvider.ts:17

Provides a strategy to visual graph authoring: which parts of the graph are editable and what is the range of possible values to allow.

Unstable: this interface will likely change in the future.

It is recommended to extend BaseMetadataProvider instead of implementing this interface directly to stay compatible with future versions.
