# Constructor Entities can be created simply by calling their constructors. Entity Constructors provide a number of overrides allowing you to customize how Entities are created. If you have Entities created in Glue then you may not need to instantiate Entities in code. Entities can be created in code if you are dynamically creating Entities (often to put in a list), or if you are creating instances of entities which will be managed purely in custom code. For additional information on creating Entities in custom code, see [this page](broken://pages/rViT6t7JgWJj1juIjptq). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.flatredball.com/flatredball/glue-reference/entities/glue-reference-constructor.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
