InMemoryFile

java.lang.Object
- org.ojalgo.netio.InMemoryFile

```
public class InMemoryFile
extends java.lang.Object
```
An in-memory "file" that can be used with some ToFileWriter and/or FromFileReaderr implementations instead of a File.
To dynamically create file contents that only exist in memory (for download): Feed an instance of InMemoryFile rather than File to a ToFileWriter that support doing so (like the TextLineWriter), and keep a reference to the InMemoryFile instance. When done writing you get the (file) contents from that instance.
To parse some data you have in memory: Create an instance of InMemoryFile using one of the constructors that take byte[] or String as input, and feed that to a FromFileReader that support doing so (like the TextLineReader).
Note that you can obtain both OutputStream and InputStream instances from an InMemoryFile – you can write to AND (later) read from the same instance.
This class is essentially a byte[] wrapper making use of ByteArrayInputStream and ByteArrayOutputStream.

Constructor Detail

InMemoryFile
```
public InMemoryFile()

InMemoryFile

public InMemoryFile(byte[] contents)

InMemoryFile

public InMemoryFile(java.lang.String contents)

Method Detail
- getContentsAsByteArray
```
public byte[] getContentsAsByteArray()
```
- getContentsAsString
```
public java.lang.String getContentsAsString()
```
- getName
```
public java.util.Optional<java.lang.String> getName()
```
  File Name
- getType
```
public java.util.Optional<java.lang.String> getType()
```
  Media (content) Type
- name
```
public InMemoryFile name(java.lang.String name)
```
- newInputStream
```
public java.io.InputStream newInputStream()
```
  Creates a new InputStream with each invocation (but keeps a reference to it for later internal use). The actual "input" is taken from the contents provided to the constructor or what was later written to an OutputStream obtained via newOutputStream().
- newOutputStream
```
public java.io.OutputStream newOutputStream()
```
  Creates a new OutputStream with each invocation (but keeps a reference to it for later internal use). Calling this method also clears any/all cached previous contents – you're expected to create new content with this.
- setName
```
public void setName(java.lang.String name)
```
- setType
```
public void setType(java.lang.String type)
```
- type
```
public InMemoryFile type(java.lang.String type)
```
