Functions

initFunction()

initFunction(config): FunctionMethods

This function looks up the function implementation based on the node's name and creates an instance configured with the provided variables and type config.

Parameters

Parameter	Type	Description
config	{ node: FunctionNode; type_config: xLuceneTypeConfig; variables?: xLuceneVariables; }	Configuration object
config.node	FunctionNode	The function node from the AST
config.type_config	xLuceneTypeConfig	Field type configuration
config.variables?	xLuceneVariables	Variables for parameter resolution

Returns

FunctionMethods

Function methods for matching and query generation

Throws

If the function name is not recognized

const functionMethods = initFunction({
  node: geoDistanceNode,
  variables: { maxDist: '10km' },
  type_config: { location: 'geo' }
});
