Binder (invokebinder 1.2 API)

java.lang.Object
- com.headius.invokebinder.Binder

```
public class Binder
extends Object
```
The Binder class provides a DSL for building a chain of MethodHandles using various of the adaptations provided by java.lang.invoke.MethodHandles. The transformations are pushed into a stack, allowing the DSL to operate forward from an incoming signature rather than backward from a target handle. This is often conceptually easier to understand, and certainly easier to read. The transformations are also applied simultaneously to the starting java.lang.invoke.MethodType, allowing Binder to check at each step whether the adaptation is valid. Here's a typical use, starting with a signature that takes two Strings and returns a String, dropping and inserting arguments, casting to a target signature, and finally calling a target handle with that signature.
```
 MethodHandle mh = Binder
     .from(String.class, String.class, String.class) // String w(String, String)
     .drop(1, String.class) // String x(String)
     .insert(0, 'hello') // String y(String, String)
     .cast(String.class, CharSequence.class, Object.class) // String z(CharSequence, Object)String
     .invoke(someTargetHandle);
 
```

  - constant
```
public java.lang.invoke.MethodHandle constant(Object value)

```
    Apply the chain of transforms and bind them to a static field retrieval specified using the end signature plus the given class and name. The field must match the end signature's return value and the end signature must take no arguments. If the final handle's type does not exactly match the initial type for this Binder, an additional cast will be attempted.
    
    Parameters:
    lookup - the MethodHandles.Lookup to use to look up the field
    target - the class in which the field is defined
    name - the field's name
    
    Returns:
    the full handle chain, bound to the given field access
    
    Throws:
    
    NoSuchFieldException
    
    IllegalAccessException
  - getStaticQuiet
```
public java.lang.invoke.MethodHandle getStaticQuiet(java.lang.invoke.MethodHandles.Lookup lookup,
                                           Class target,
                                           String name)
```
    Apply the chain of transforms and bind them to a static field retrieval specified using the end signature plus the given class and name. The field must match the end signature's return value and the end signature must take no arguments. If the final handle's type does not exactly match the initial type for this Binder, an additional cast will be attempted. This version is "quiet" in that it throws an unchecked InvalidTransformException if the target method does not exist or is inaccessible.
    
    Parameters:
    lookup - the MethodHandles.Lookup to use to look up the field
    target - the class in which the field is defined
    name - the field's name
    
    Returns:
    the full handle chain, bound to the given field access
  - setField

                                              IllegalAccessException
```
    Apply the chain of transforms and bind them to an object field assignment specified using the end signature plus the given class and name. The end signature must take the target class or a subclass and the field's type as its arguments, and its return type must be compatible with void. If the final handle's type does not exactly match the initial type for this Binder, an additional cast will be attempted.
    
    Parameters:
    lookup - the MethodHandles.Lookup to use to look up the field
    name - the field's name
    
    Returns:
    the full handle chain, bound to the given field assignment
    
    Throws:
    
    NoSuchFieldException
    
    IllegalAccessException

  - arraySet
```
public java.lang.invoke.MethodHandle arraySet()
```
    Apply the chain of transforms and bind them to an array element set. The signature at the endpoint must return void and receive the array type, int index, and array element type.
    
    Returns:
    the full handle chain, bound to an array element set.
  - arrayGet
```
public java.lang.invoke.MethodHandle arrayGet()
```
    Apply the chain of transforms and bind them to an array element get. The signature at the endpoint must return the array element type and receive the array type and int index.
    
    Returns:
    the full handle chain, bound to an array element get.
  - branch
```
public java.lang.invoke.MethodHandle branch(java.lang.invoke.MethodHandle test,
                                   java.lang.invoke.MethodHandle truePath,
                                   java.lang.invoke.MethodHandle falsePath)
```
    Apply the chain of transforms and bind them to a boolean branch as from java.lang.invoke.MethodHandles.guardWithTest. As with GWT, the current endpoint signature must match the given target and fallback signatures.
    
    Parameters:
    test - the test handle
    truePath - the target handle
    falsePath - the fallback handle
    
    Returns:
    the full handle chain bound to a branch
  - invoker
```
public java.lang.invoke.MethodHandle invoker()
