StatFs

java.lang.Object

public class StatFs extends Object

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

Fields Summary
private int
mNativeContext
Constructors Summary
public StatFs(String path)
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.
param
path A path in the desired file system to state.
native_setup(path);
Methods Summary
protected void finalize()
native_finalize();
public native int getAvailableBlocks()
The number of blocks that are free on the file system and available to applications. This corresponds to the Unix statfs.f_bavail field.
public native int getBlockCount()
The total number of blocks on the file system. This corresponds to the Unix statfs.f_blocks field.
public native int getBlockSize()
The size, in bytes, of a block on the file system. This corresponds to the Unix statfs.f_bsize field.
public native int getFreeBlocks()
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 statfs.f_bfree field. Most applications will want to use {@link #getAvailableBlocks()} instead.
private native void native_finalize()
private native void native_restat(java.lang.String path)
private native void native_setup(java.lang.String path)
public void restat(java.lang.String path)
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.
native_restat(path);
