Method Details

getId

public String getId()

Description copied from interface: FunctionDefinition

The ID of this function.

Specified by:

getId in interface FunctionDefinition

Returns:

The ID string

getCost

public int getCost()

Description copied from interface: FunctionDefinition

Returns the relative cost of evaluating this function.

Lower values indicate cheaper operations. This cost is used by BDD optimizations to prefer evaluating cheaper conditions earlier, enabling short-circuit evaluation to skip expensive operations when possible.

Specified by:

getCost in interface FunctionDefinition

Returns:

the relative evaluation cost (default: 100)

getArguments

public List<Type> getArguments()

Description copied from interface: FunctionDefinition

The arguments to this function.

Specified by:

getArguments in interface FunctionDefinition

Returns:

The function arguments

getReturnType

public Type getReturnType()

Description copied from interface: FunctionDefinition

The return type of this function definition.

Specified by:

getReturnType in interface FunctionDefinition

Returns:

The function return type

evaluate

public Value evaluate(List<Value> arguments)

Description copied from interface: FunctionDefinition

Evaluate the arguments to a given function to compute a result.

Specified by:

evaluate in interface FunctionDefinition

Returns:

The resulting value

createFunction

public Not createFunction(FunctionNode functionNode)

Description copied from interface: FunctionDefinition

Creates a LibraryFunction implementation from the given FunctionNode.

Specified by:

createFunction in interface FunctionDefinition

Parameters:

functionNode - the function node to deserialize.

Returns:

the created LibraryFunction implementation.
