- org.springframework.core.io.AbstractResource
- - org.springframework.core.io.InputStreamResource

All Implemented Interfaces:
InputStreamSource, Resource
```
public class InputStreamResource
extends AbstractResource
```
Resource implementation for a given InputStream.
Should only be used if no other specific Resource implementation is applicable. In particular, prefer ByteArrayResource or any of the file-based Resource implementations where possible.
In contrast to other Resource implementations, this is a descriptor for an already opened resource - therefore returning true from isOpen(). Do not use an InputStreamResource if you need to keep the resource descriptor somewhere, or if you need to read from a stream multiple times.

- Constructor Detail
  - InputStreamResource
```
public InputStreamResource(InputStream inputStream)
```
    Create a new InputStreamResource.
    Parameters:
    inputStream - the InputStream to use
  - InputStreamResource
```
public InputStreamResource(InputStream inputStream,
                           String description)
```
    Create a new InputStreamResource.
    Parameters:
    inputStream - the InputStream to use
    description - where the InputStream comes from
- Method Detail
  - exists
```
public boolean exists()
```
    This implementation always returns true.
    Specified by:
    exists in interface Resource
    Overrides:
    exists in class AbstractResource
  - isOpen
```
public boolean isOpen()
```
    This implementation always returns true.
    Specified by:
    isOpen in interface Resource
    Overrides:
    isOpen in class AbstractResource
  - getInputStream
```
public InputStream getInputStream()
                           throws IOException,
                                  IllegalStateException
```
    This implementation throws IllegalStateException if attempting to read the underlying stream multiple times.
    Returns:
    the input stream for the underlying resource (must not be null)
    Throws:
    FileNotFoundException - if the underlying resource doesn't exist
    IOException - if the content stream could not be opened
    IllegalStateException
  - getDescription
```
public String getDescription()
```
    This implementation returns a description that includes the passed-in description, if any.
    See Also:
    Object.toString()
  - equals
```
public boolean equals(Object obj)
```
    This implementation compares the underlying InputStream.
    Overrides:
    equals in class AbstractResource
    See Also:
    Resource.getDescription()
  - hashCode
```
public int hashCode()
```
    This implementation returns the hash code of the underlying InputStream.
    Overrides:
    hashCode in class AbstractResource
