ContractStaticImports

Object
- com.u7.jthereum.ContractStaticImports

```
public class ContractStaticImports
extends Object
```
This class encapsulates the values and methods that may be accessed from within the context of a contract method executing on the blockchain.
It is suggested that you use a static import to include these values and methods in the context of your contract code:
import static com.u7.ContractStaticImports.*;
Note that these members and methods are not intended to be accessed within the context of running Java code on the JVM at this time. They are simply placeholders that are used to help express your desired contract behavior in Java code.
A future release may implement JVM based simulation of Blockchain Side execution, however this feature is not available yet.
To put it another way, *only* access these from inside code that is intended for execution on the blockchain.

```
public static void require(boolean condition,
                           String message)
```
    Similar to Java 'assert'. If the required condition is false then execution of the transaction will terminate and any changes to the blockchain will be reverted.
    
    Parameters:
    
    condition - the condition that hopefully will be true
    
    message - a message that describes what went wrong if condition is false. Curently there is no way to retrieve this message value.
  - revert
```
public static void revert()
                   throws Error
```
    Similar to Java 'assert false'. The transaction will terminate and any changes to the blockchain will be reverted.
    
    Throws:
    
    Error - this method is tagged as throwing an Error to represent the fact that the flow of control will terminate after this method is invoked.

  - selfdestruct
```
public static void selfdestruct(Address recipient)

```
public static <T> T toContract(Class<T> contractClass,
                               Address a)
```
    Helper method to convert an address into a reference to the appropriate contract class that is deployed at that address. Note that no type checking is performed. It is the duty of the programmer to ensure that the address provided implements methods that are compatible with the provided Java contract class. The returned reference may be used within contract code to in turn call another contract.
    
    Type Parameters:
    
    T - The type of the contract class
    
    Parameters:
    
    contractClass - the class type to cast the address into
    
    a - the address of the deployed contract
    
    Returns:
    
    a reference to a contract of the specified type
