Description

Loads the content of the datasets associated with TFDCustomSchemaAdapter from a file.

Call the LoadFromFile procedure to load the content of the datasets associated with TFDCustomSchemaAdapter from a specific file with a specific format.

AFileName is the name of the file containing the adapter to load. If the file does not exist, an exception is raised.

AFormat is the file format:

  • sfXML: an XML file.
  • sfBinary: a binary file with custom FireDAC format.
  • sfAuto: the format is determined by the AFileName extention: ".XML" - XML file, ".ADB" / ".BIN" / ".DAT"--binary file.

Note: If the AFileName does not have an extension, the format is determined by ResourceOptions.DefaultStoreExt, provided that it is specified. Otherwise, it is determined by ResourceOptions.DefaultStoreFormat.
