| Class and Description |
|---|
| FunctionDescription
A description of a function, including its name, description, and argument names.
|
| ScalarValuedFunction
The description of a function taking record data and producing a scalar result.
|
| Class and Description |
|---|
| FunctionProvider
A provider of registered classes for the
FunctionRegistry. |
| ScalarValuedFunction
The description of a function taking record data and producing a scalar result.
|
| SimpleFunctionProvider
Convenient base class for implementations of
FunctionProvider. |
| Class and Description |
|---|
| ScalarValuedFunction
The description of a function taking record data and producing a scalar result.
|
| Class and Description |
|---|
| ArgumentConverter
An ArgumentConverter is used by the
DefaultFunctionInvoker to convert
ScalarValuedFunction arguments to the correct type. |
| ConstantArgumentConverter
An abstract argument converter for converting String constants to the
correct object type.
Child classes should implement the convert(String) object to produce an object. |
| DateTime.DateTimeValue
Definitions of date and time values that can be extracted from date and timestamp types.
|
| DateTime.Granularity
The desired granularity of the output.
|
| EvaluationContext
An object describing the context in which a subexpression of a
larger expression is being evaluated.
|
| EvaluatorFactory
A factory used to construct evaluators for
ScalarValuedFunctions. |
| FunctionContext
Information about the context in which a function is
evaluated.
|
| FunctionDescription
A description of a function, including its name, description, and argument names.
|
| FunctionEvaluator
An executor of a function.
|
| FunctionInvoker
A FunctionInvoker is used by the FunctionRegistry to invoke a function method and by
the AggregationInvoker to invoke an aggregation method.
The implementing class essentially translates an array of ScalarValuedFunction arguments into the proper format for a given function method. A function method can specify its invoker using the Invoker annotation. |
| FunctionProvider
A provider of registered classes for the
FunctionRegistry. |
| FunctionRegistry
Stores a list of functions registered by the FunctionTypeResoultionProvider, and
provides a method for calling those functions.
|
| FunctionTyper
Determines the upper bound and result type of a
ScalarValuedFunction. |
| MappedEvaluatorFactory
A base class for factories which choose an evaluator based on a
token type.
|
| MappedEvaluatorFactory.Mapping
Defines a mapping between data type and an evaluator class.
|
| ScalarFunctionDescriptor.SubexpressionBound
Specifies a bound on subexpressions used as arguments to a function.
|
| ScalarValuedFunction
The description of a function taking record data and producing a scalar result.
|
| SimpleFunctionProvider
Convenient base class for implementations of
FunctionProvider. |
| Strings.NullConcatenation
Specifies behavior of null values for string concatenation.
