Class Overview

Retrieve overall information about the space on a filesystem. This is a wrapper for Unix statvfs().

Summary

Public Constructors
StatFs(String path)
Construct a new StatFs for looking at the stats of the filesystem at path.
Public Methods
int getAvailableBlocks()
long getAvailableBlocksLong()
The number of blocks that are free on the file system and available to applications.
long getAvailableBytes()
The number of bytes that are free on the file system and available to applications.
int getBlockCount()
long getBlockCountLong()
The total number of blocks on the file system.
int getBlockSize()
long getBlockSizeLong()
The size, in bytes, of a block on the file system.
int getFreeBlocks()
long getFreeBlocksLong()
The total number of blocks that are free on the file system, including reserved blocks (that are not available to normal applications).
long getFreeBytes()
The number of bytes that are free on the file system, including reserved blocks (that are not available to normal applications).
long getTotalBytes()
The total number of bytes supported by the file system.
void restat(String path)
Perform a restat of the file system referenced by this object.

Public Constructors

public StatFs (String path)

Added in API level 1

Construct a new StatFs for looking at the stats of the filesystem at path. Upon construction, the stat of the file system will be performed, and the values retrieved available from the methods on this class.

Parameters
path path in the desired file system to stat.

Public Methods

public int getAvailableBlocks ()

Added in API level 1

This method was deprecated in API level 18.
Use getAvailableBlocksLong() instead.

public long getAvailableBlocksLong ()

Added in API level 18

The number of blocks that are free on the file system and available to applications. This corresponds to the Unix statvfs.f_bavail field.

public long getAvailableBytes ()

Added in API level 18

The number of bytes that are free on the file system and available to applications.

public int getBlockCount ()

Added in API level 1

This method was deprecated in API level 18.
Use getBlockCountLong() instead.

public long getBlockCountLong ()

Added in API level 18

The total number of blocks on the file system. This corresponds to the Unix statvfs.f_blocks field.

public int getBlockSize ()

Added in API level 1

This method was deprecated in API level 18.
Use getBlockSizeLong() instead.

public long getBlockSizeLong ()

Added in API level 18

The size, in bytes, of a block on the file system. This corresponds to the Unix statvfs.f_bsize field.

public int getFreeBlocks ()

Added in API level 1

This method was deprecated in API level 18.
Use getFreeBlocksLong() instead.

public long getFreeBlocksLong ()

Added in API level 18

The total number of blocks that are free on the file system, including reserved blocks (that are not available to normal applications). This corresponds to the Unix statvfs.f_bfree field. Most applications will want to use getAvailableBlocks() instead.

public long getFreeBytes ()

Added in API level 18

The number of bytes that are free on the file system, including reserved blocks (that are not available to normal applications). Most applications will want to use getAvailableBytes() instead.

public long getTotalBytes ()

Added in API level 18

The total number of bytes supported by the file system.

public void restat (String path)

Added in API level 1

Perform a restat of the file system referenced by this object. This is the same as re-constructing the object with the same file system path, and the new stat values are available upon return.
