Interface ExecutableBinder<S>

Type Parameters:

S - The source type

All Known Implementing Classes:

DefaultExecutableBinder

public interface ExecutableBinder<S>

An ExecutableBinder is capable of taking a target Executable and fulfilling the argument requirements using the provided binding source and ArgumentBinderRegistry

The returned BoundExecutable will have all of the required arguments bound and can then be called simply by calling invoke.

If an argument could not be bound then an exception will be

Method Summary

Modifier and Type	Method and Description
<T,R> BoundExecutable<T,R>	bind(Executable<T,R> target, ArgumentBinderRegistry<S> registry, S source) Binds a given Executable using the given registry and source object.
<T,R> BoundExecutable<T,R>	tryBind(Executable<T,R> target, ArgumentBinderRegistry<S> registry, S source) Binds a given Executable using the given registry and source object.

Method Detail

bind

<T,R> BoundExecutable<T,R> bind(Executable<T,R> target,
                                ArgumentBinderRegistry<S> registry,
                                S source)
                         throws UnsatisfiedArgumentException

Binds a given Executable using the given registry and source object.

Type Parameters:

T - The executable target type

R - The executable return type

Parameters:

target - The target executable

registry - The registry to use

source - The binding source

Returns:

The bound executable

Throws:

UnsatisfiedArgumentException - When the executable could not be satisfied

tryBind

<T,R> BoundExecutable<T,R> tryBind(Executable<T,R> target,
                                   ArgumentBinderRegistry<S> registry,
                                   S source)

Binds a given Executable using the given registry and source object. Unlike bind(Executable, ArgumentBinderRegistry, Object) this method will not throw an UnsatisfiedArgumentException if an argument cannot be bound. Instead the BoundExecutable.getUnboundArguments() property will be populated with any arguments that could not be bound

Type Parameters:

T - The executable target type

R - The executable return type

Parameters:

target - The target executable

registry - The registry to use

source - The binding source

Returns:

The bound executable
