SizeLimitedOutputStream

public class SizeLimitedOutputStream
extends Object

java.lang.Object
↳	com.android.tradefed.util.SizeLimitedOutputStream

A thread safe file backed ERROR(/OutputStream) that limits the maximum amount of data that can be written.

This is implemented by keeping a circular list of Files of fixed size. Once a File has reached a certain size, the class jumps to use the next File in the list. If the next File is non empty, it is deleted, and a new file created.

Summary

Public constructors
`SizeLimitedOutputStream(long maxDataSize, int numFiles, String tempFilePrefix, String tempFileSuffix)` Creates a `SizeLimitedOutputStream`.
`SizeLimitedOutputStream(long maxDataSize, String tempFilePrefix, String tempFileSuffix)` Creates a `SizeLimitedOutputStream` with default number of backing files.

Public methods
`void`	`close()` Closes the write stream
`void`	`delete()` Delete all accumulated data.
`void`	`flush()`
`InputStream`	`getData()` Gets the collected output as a `ERROR(/InputStream)`.
`void`	`write(byte[] b, int off, int len)`
`void`	`write(int data)`

Public constructors

SizeLimitedOutputStream

public SizeLimitedOutputStream (long maxDataSize, 
                int numFiles, 
                String tempFilePrefix, 
                String tempFileSuffix)

Creates a SizeLimitedOutputStream.

Parameters
`maxDataSize`	`long`: the approximate max size in bytes to keep in the output stream
`numFiles`	`int`: the max number of backing files to use to store data. Higher values will mean max data kept will be close to maxDataSize, but with a possible performance penalty.
`tempFilePrefix`	`String`: prefix to use for temporary files
`tempFileSuffix`	`String`: suffix to use for temporary files

SizeLimitedOutputStream

public SizeLimitedOutputStream (long maxDataSize, 
                String tempFilePrefix, 
                String tempFileSuffix)

Creates a SizeLimitedOutputStream with default number of backing files.

Parameters
`maxDataSize`	`long`: the approximate max size to keep in the output stream
`tempFilePrefix`	`String`: prefix to use for temporary files
`tempFileSuffix`	`String`: suffix to use for temporary files

Public methods

close

public void close ()

Closes the write stream

delete

public void delete ()

Delete all accumulated data.

flush

public void flush ()

getData

write

public void write (byte[] b, 
                int off,

`off`	`int`
`len`	`int`

write

public void write (int data)

Parameters
`data`	`int`
