Remarks

The model is a type named {QueryName}Parameters or {ReadModelName}{QueryName}Parameters in the read model's assembly, whose properties cover every parameter of the query. The same convention is what the proxy generator uses to find the rules it emits into the client, so both sides resolve the same type and validate the same shape.

Constructors

QueryArgumentsModels(ILogger<QueryArgumentsModels>)

Represents an implementation of IQueryArgumentsModels that resolves the arguments model by convention.

public QueryArgumentsModels(ILogger<QueryArgumentsModels> logger)

Parameters

logger ILogger<QueryArgumentsModels>

The ILogger<TCategoryName> used to log a model that cannot be materialized.

Remarks

The model is a type named {QueryName}Parameters or {ReadModelName}{QueryName}Parameters in the read model's assembly, whose properties cover every parameter of the query. The same convention is what the proxy generator uses to find the rules it emits into the client, so both sides resolve the same type and validate the same shape.

Methods

TryCreateFor(IQueryPerformer, QueryArguments, out object)

Tries to materialize the arguments model for a query from the arguments it was called with.

public bool TryCreateFor(IQueryPerformer performer, QueryArguments arguments, out object model)

Parameters

performer IQueryPerformer

The IQueryPerformer for the query.

arguments QueryArguments

The QueryArguments the query was called with.

model object

The materialized model when the query has one.

Returns

bool

True when the query has an arguments model and it could be materialized; otherwise false.
