java.lang.Object
- io.vavr.control.Try.Failure<T>

Type Parameters:

T - the type of the value that would have been contained if successful

All Implemented Interfaces:

Try<T>, Value<T>, java.io.Serializable, java.lang.Iterable<T>

Enclosing interface:

Try<T>
```
public static final class Try.Failure<T>
extends java.lang.Object
implements Try<T>, java.io.Serializable
```
Represents a failed Try containing a Throwable as the cause.
Instances of this class indicate that the computation threw an exception and do not contain a successful value.
```
 Try<Integer> failure = new Try.Failure<>(new RuntimeException("error"));
 failure.isFailure();  // true
 failure.getCause();   // RuntimeException: error
 
```

private Failure(java.lang.Throwable cause)
```
    Constructs a Failure.
    
    Parameters:
    
    cause - A cause of type Throwable, may not be null.
    
    Throws:
    
    java.lang.NullPointerException - if cause is null. Additionally, if the given cause is fatal (i.e. non-recoverable), it is thrown sneakily without being declared in the method signature.

  - get
```
public T get()
```
    Description copied from interface: Try
    
    Returns the value of this Try if it is a Try.Success, or throws the underlying exception if it is a Try.Failure.
    Important: If this Try is a Try.Failure, the exception thrown is exactly the Try.getCause() of this Failure. The underlying cause is thrown sneakily (without being declared in the method signature).
    
    Specified by:
    
    get in interface Try<T>
    
    Specified by:
    
    get in interface Value<T>

    the value contained in this Success
  - getCause
```
public java.lang.Throwable getCause()
```
    Description copied from interface: Try
    
    Returns the cause of failure if this Try is a Try.Failure.
    
    Specified by:
    
    getCause in interface Try<T>
    
    Returns:
    
    the throwable cause of this Try.Failure
  - isEmpty
```
public boolean isEmpty()
```
    Description copied from interface: Try
    
    Checks whether this Try contains no value, i.e., it is a Try.Failure.

  - isFailure
```
public boolean isFailure()
```
    Description copied from interface: Try
    
    Checks whether this Try is a Try.Failure.
    
    Specified by:
    
    isFailure in interface Try<T>
    
    Returns:
    
    true if this is a Try.Failure, false if this is a Try.Success
