SimpleFunctionRegistryBase¶

SimpleFunctionRegistryBase is an extension of the FunctionRegistryBase abstraction for function registries.

Implementations¶

• SimpleFunctionRegistry
• SimpleTableFunctionRegistry

registerFunction¶

registerFunction(
  name: FunctionIdentifier,
  info: ExpressionInfo,
  builder: FunctionBuilder): Unit

registerFunction internalRegisterFunction with a normalized (lower-case) name.

registerFunction is part of the FunctionRegistryBase abstraction.

internalRegisterFunction¶

internalRegisterFunction(
  name: FunctionIdentifier,
  info: ExpressionInfo,
  builder: FunctionBuilder): Unit

internalRegisterFunction adds a new function to the functionBuilders registry.

internalRegisterFunction is used when;

• SimpleFunctionRegistryBase is requested to registerFunction
• FunctionRegistry utility is used to create a SimpleFunctionRegistry with built-in functions
• TableFunctionRegistry utility is used to create a SimpleTableFunctionRegistry with built-in functions
