GetSymbolAsync(IEnumerable<String>)
Asynchronously returns a symbol based on the provided list of keys.
Declaration
public Task<Symbol> GetSymbolAsync(IEnumerable<string> keys)Parameters
| Type | Name | Description |
|---|---|---|
| System.Collections.Generic.IEnumerable<System.String> | keys | System.Collections.Generic.IEnumerable<T> of System.String type value. It is the list of keys required to obtain a symbol from the style. |
Returns
| Type | Description |
|---|---|
| System.Threading.Tasks.Task<Symbol> | The task object representing the asynchronous getSymbol as operation. The value of the task result is a Symbol object. |
Remarks
This function is useful for obtaining a single multilayer symbol from supplied keys. This is commonly used to create symbols and graphics on-the-fly. For example, assume XYZ style has a symbol with key "abc" which is the central symbol and another symbol with key "pqr", which could be the modifier/echelon placed at some offset from central geometry. So if you provide these two keys as attributes then symbol style will find and assemble a symbol accordingly. Once you have that symbol, you can apply it to a Graphic or Renderer, obtain its swatch image, or serialize to JSON. If the Symbol style is not loaded then starting this task will start the load cycle.
