Examples of com.linkedin.data.schema.DataSchemaResolver

com.linkedin.data.schema.DataSchemaResolver
A {@link DataSchemaResolver} is used to resolve names to {@link NamedDataSchema}s.
A {@link SchemaParser} uses {@link #existingDataSchema(String)} to determine if a name has alreadybeen resolved to a {@link NamedDataSchema}. The returned {@link NamedDataSchema} may notbe complete or well-formed due to circular references.
A {@link SchemaParser} uses {@link #findDataSchema(String,StringBuilder)} to request theresolving an unresolved name to a {@link NamedDataSchema}. This may be done by searching jar files or directories for files whose file names computed from the provided name similar to how Java resolves class names to source or binary files.
The contract between a {@link SchemaParser} and its {@link DataSchemaResolver} requiresthe {@link SchemaParser} to invoke {@link #bindNameToSchema(Name,NamedDataSchema,DataSchemaLocation)}to bind all possible names (its declared name and aliases) to a newly constructed {@link NamedDataSchema}before {@link SchemaParser} attempts to lookup or resolve names referenced by the {@link NamedDataSchema}. This means that when the name is bound, the {@link NamedDataSchema} is incomplete. This contractis required to implement circular references.
