Modifier and Type	Method and Description
SourceSnippet	createConstructorInjection(MethodLiteral<?,Constructor<?>> constructor, NameGenerator nameGenerator, List<InjectorMethod> methodsOutput) Creates a constructor injecting method and returns a string that invokes the new method.
SourceSnippet	createMethodCallWithInjection(MethodLiteral<?,?> method, String invokeeName, NameGenerator nameGenerator, List<InjectorMethod> methodsOutput) Creates a method that calls the passed method, injecting its parameters using getters, and returns a string that invokes the new method.
SourceSnippet	createMethodCallWithInjection(MethodLiteral<?,?> method, String invokeeName, String[] parameterNames, NameGenerator nameGenerator, List<InjectorMethod> methodsOutput) Creates a method that calls the passed method, injecting its parameters using getters as necessary, and returns a string that invokes the new method.

createConstructorInjection

public SourceSnippet createConstructorInjection(MethodLiteral<?,Constructor<?>> constructor,
                                                NameGenerator nameGenerator,
                                                List<InjectorMethod> methodsOutput)
                                         throws NoSourceNameException

Creates a constructor injecting method and returns a string that invokes the new method. The new method returns the constructed object.

Parameters:

constructor - constructor to call

nameGenerator - NameGenerator to be used for ensuring method name uniqueness

methodsOutput - a list where all new methods created by this call are added

Returns:

source snippet calling the generated method

Throws:

NoSourceNameException

createMethodCallWithInjection

public SourceSnippet createMethodCallWithInjection(MethodLiteral<?,?> method,
                                                   String invokeeName,
                                                   NameGenerator nameGenerator,
                                                   List<InjectorMethod> methodsOutput)
                                            throws NoSourceNameException

Creates a method that calls the passed method, injecting its parameters using getters, and returns a string that invokes the new method. The new method returns the passed method's return value, if any. If a method without parameters is provided, that method will be called and no parameters will be passed.

Parameters:

method - method to call (can be constructor)

invokeeName - expression that evaluates to the object on which the method is to be called. If null the method will be called in the current scope.

nameGenerator - NameGenerator to be used for ensuring method name uniqueness

methodsOutput - a list where all new methods created by this call are added

Returns:

source snippet calling the generated method

Throws:

NoSourceNameException

createMethodCallWithInjection

public SourceSnippet createMethodCallWithInjection(MethodLiteral<?,?> method,
                                                   String invokeeName,
                                                   String[] parameterNames,
                                                   NameGenerator nameGenerator,
                                                   List<InjectorMethod> methodsOutput)
                                            throws NoSourceNameException

Creates a method that calls the passed method, injecting its parameters using getters as necessary, and returns a string that invokes the new method. The new method returns the passed method's return value, if any. If a method without parameters is provided, that method will be called and no parameters will be passed. If the passed method declared any checked exceptions, the generated method will catch and rethrow those as CreationException.

Parameters:

method - method to call (can be constructor)

invokeeName - expression that evaluates to the object on which the method is to be called. If null the method will be called in the current scope.

parameterNames - array with parameter names that can replace getter methods (usually used to fetch injected values) in the returned string. The array length must match the number of method parameters. A null value denotes that the getter method should be used.

nameGenerator - NameGenerator to use for ensuring method name uniqueness

methodsOutput - a list where all new methods created by this call are added

Returns:

string calling the generated method

Throws:

NoSourceNameException
