Preconditions (common 3.0.0.Beta2-SNAPSHOT API)

java.lang.Object
- org.cloudburstmc.protocol.common.util.Preconditions

```
public final class Preconditions
extends java.lang.Object
```
Static convenience methods that help a method or constructor check whether it was invoked correctly (that is, whether its preconditions were met).
If the precondition is not met, the Preconditions method throws an unchecked exception of a specified type, which helps the method in which the exception was thrown communicate that its caller has made a mistake. This allows constructs such as
```
 public static double sqrt(double value) {
   if (value < 0) {
     throw new IllegalArgumentException("input is negative: " + value);
   }
   // calculate square root
 }
 
```
to be replaced with the more compact
```
 public static double sqrt(double value) {
   checkArgument(value >= 0, "input is negative: %s", value);
   // calculate square root
 }
 
```
so that a hypothetical bad caller of this method, such as:
```
   void exampleBadCaller() {
     double d = sqrt(-1.0);
 }
 
```
would be flagged as having called sqrt() with an illegal argument.
Performance

Avoid passing message arguments that are expensive to compute; your code will always compute them, even though they usually won't be needed. If you have such arguments, use the conventional if/throw idiom instead.
Depending on your message arguments, memory may be allocated for boxing and varargs array creation. However, the methods of this class have a large number of overloads that prevent such allocations in many common cases.
The message string is not formatted unless the exception will be thrown, so the cost of the string formatting itself should not be a concern.
As with any performance concerns, you should consider profiling your code (in a production environment if possible) before spending a lot of effort on tweaking a particular element.
Other types of preconditions

Not every type of precondition failure is supported by these methods. Continue to throw standard JDK exceptions such as NoSuchElementException or UnsupportedOperationException in the situations they are intended for.
Non-preconditions

It is of course possible to use the methods of this class to check for invalid conditions which are not the caller's fault. Doing so is not recommended because it is misleading to future readers of the code and of stack traces. See Conditional failures explained in the Guava User Guide for more advice.
java.util.Objects.requireNonNull()

Projects which use com.google.common should generally avoid the use of Objects.requireNonNull(Object). Instead, use whichever of checkNotNull(Object) is appropriate to the situation. (The same goes for the message-accepting overloads.)
Only %s is supported

In Preconditions error message template strings, only the "%s" specifier is supported, not the full range of Formatter specifiers.

```
public static void checkArgument(boolean expression)
```
    Ensures the truth of an expression involving one or more parameters to the calling method.
    
    Parameters:
    
    expression - a boolean expression
    
    Throws:
    
    java.lang.IllegalArgumentException - if expression is false
  - checkArgument
```
public static void checkArgument(boolean expression,
                                 @Nullable java.lang.Object errorMessage)
```
    Ensures the truth of an expression involving one or more parameters to the calling method.
    
    Parameters:
    
    expression - a boolean expression
    
    errorMessage - the exception message to use if the check fails; will be converted to a string using String.valueOf(Object)
    
    Throws:
    
    java.lang.IllegalArgumentException - if expression is false
  - checkArgument
```
public static void checkArgument(boolean expression,
                                 @Nullable java.lang.String errorMessageTemplate,
                                 java.lang.Object... errorMessageArgs)
```
    Ensures the truth of an expression involving one or more parameters to the calling method.
    
    Parameters:
    
    expression - a boolean expression
    
    errorMessageTemplate - a template for the exception message should the check fail. The message is formed by replacing each %s placeholder in the template with an argument. These are matched by position - the first %s gets errorMessageArgs[0], etc. Unmatched arguments will be appended to the formatted message in square braces. Unmatched placeholders will be left as-is.
    
    errorMessageArgs - the arguments to be substituted into the message template. Arguments are converted to strings using String.valueOf(Object).
    
    Throws:
    
    java.lang.IllegalArgumentException - if expression is false

    Ensures the truth of an expression involving the state of the calling instance, but not involving any parameters to the calling method.
    
    Parameters:
    
    expression - a boolean expression
    
    Throws:

    Parameters:
    
    expression - a boolean expression
    
    errorMessage - the exception message to use if the check fails; will be converted to a string using String.valueOf(Object)

    Parameters:
    
    expression - a boolean expression
    
    errorMessageTemplate - a template for the exception message should the check fail. The message is formed by replacing each %s placeholder in the template with an argument. These are matched by position - the first %s gets errorMessageArgs[0], etc. Unmatched arguments will be appended to the formatted message in square braces. Unmatched placeholders will be left as-is.
    
    errorMessageArgs - the arguments to be substituted into the message template. Arguments are converted to strings using String.valueOf(Object).
    
    Throws:

```
public static <T> T checkNotNull(T reference)
```
    Ensures that an object reference passed as a parameter to the calling method is not null.
    
    Parameters:
    
    reference - an object reference
    
    Returns:
    
    the non-null reference that was validated
    
    Throws:
    
    java.lang.NullPointerException - if reference is null
  - checkNotNull
```
public static <T> T checkNotNull(T reference,

```
    Ensures that an object reference passed as a parameter to the calling method is not null.
    
    Parameters:
    
    reference - an object reference
    
    errorMessage - the exception message to use if the check fails; will be converted to a string using String.valueOf(Object)
    
    Returns:
    
    the non-null reference that was validated
    
    Throws:
    
    java.lang.NullPointerException - if reference is null

```
    Ensures that an object reference passed as a parameter to the calling method is not null.
    
    Parameters:
    
    reference - an object reference
    
    errorMessageTemplate - a template for the exception message should the check fail. The message is formed by replacing each %s placeholder in the template with an argument. These are matched by position - the first %s gets errorMessageArgs[0], etc. Unmatched arguments will be appended to the formatted message in square braces. Unmatched placeholders will be left as-is.
    
    errorMessageArgs - the arguments to be substituted into the message template. Arguments are converted to strings using String.valueOf(Object).
    
    Returns:
    
    the non-null reference that was validated
    
    Throws:
    
    java.lang.NullPointerException - if reference is null
