Class StaticMethodReflection

java.lang.Object
  r01f.reflection.fluent.StaticMethodReflection

public final class StaticMethodReflection
extends java.lang.Object

Static methoc reflection. Usage example:

   // Equivalent to call 'Jedi.setCommonPower("Jump")'
   Reflection.staticMethod("setCommonPower").withParameterTypes(String.class).in(Jedi.class).invoke("Jump");
 
   // Equivalent to call 'Jedi.addPadawan()'
   Reflection.staticMethod("addPadawan").in(Jedi.class).invoke();
 
   // Equivalent to call 'Jedi.commonPowerCount()'
   String name = Reflection.staticMethod("commonPowerCount").withReturnType(String.class).in(Jedi.class).invoke();
 
   // Equivalent to call 'Jedi.getCommonPowers()'
   List powers = Reflection.staticMethod("getCommonPowers").withReturnType(new TypeRef>() {}).in(Jedi.class).invoke}();

Method Detail

startStaticMethodAccess

static StaticMethodReflection startStaticMethodAccess(java.lang.String methodName)

Creates a new StaticMethodReflection: the starting point of the fluent interface for accessing static methods using Java Reflection.

Parameters:

methodName - the name of the method to access using Java Reflection.

Returns:

the created StaticMethodName.

Throws:

java.lang.NullPointerException - if the given name is null.

java.lang.IllegalArgumentException - if the given name is empty.

withReturnType

public <T> StaticMethodReturnTypes.StaticMethodReturnType<T> withReturnType(java.lang.Class<T> type)

Specifies the return type of the static method to invoke. This method call is optional if the return type of the method to invoke is void.

Type Parameters:

T - the generic type of the method's return type.

Parameters:

type - the return type of the method to invoke.

Returns:

the created return type holder.

Throws:

java.lang.NullPointerException - if the given type is null.

withReturnType

public <T> StaticMethodReturnTypes.StaticMethodReturnTypeGenerics<T> withReturnType(TypeRef<T> type)

Specifies the return type reference of the static method to invoke. This method call is optional if the return type of the method to invoke is void.

Type Parameters:

T - the generic type of the method's return type.

Parameters:

type - the return type reference of the method to invoke.

Returns:

the created return type holder.

Throws:

java.lang.NullPointerException - if the given type reference is null.

withParameterTypes

public StaticMethodParameterTypes<java.lang.Void> withParameterTypes(java.lang.Class<?>... parameterTypes)

Specifies the parameter types of the static method to invoke. This method call is optional if the method to invoke does not take arguments.

Parameters:

parameterTypes - the parameter types of the method to invoke.

Returns:

the created parameter types holder.

Throws:

java.lang.NullPointerException - if the array of parameter types is null.

public MethodInvoker<java.lang.Void> in(java.lang.Class<?> target)

Creates a new invoker for a static method that takes no parameters and return value void.

Parameters:

target - the object containing the method to invoke.

Returns:

the created method invoker.

Throws:

java.lang.NullPointerException - if the given target is null.
