Package ghidra.formats.gfilesystem

Class FSRLRoot

java.lang.Object

ghidra.formats.gfilesystem.FSRL

ghidra.formats.gfilesystem.FSRLRoot

public class FSRLRoot
extends FSRL

A type of FSRL that is specific to the filesystem's identity. A FSRL's parent is always a FSRLRoot.

A FSRLRoot's parent is always a FSRL (ie. the container the filesystem data is in), or null.

Examples of relationship between FSRL and FSRLRoots:

• FSRLRoot [ file:// ]
  "file://"
• FSRLRoot [ file:// ] <---- FSRL [ /filename.txt ]
  "file:///filename.txt"
• FSRLRoot [ file:// ] <---- FSRL [ /filename.txt ] <--- FSRLRoot [ subfs:// ]
  "file:///filename.txt|subfs://"

Method Summary

Modifier and Type	Method	Description
protected void	appendToStringBuilder(StringBuilder sb, boolean recurse, boolean includeParams, boolean includeFSRoot)
FSRL	getContainer()	Returns the parent containerfile FSRL, or null if this FSRLRoot specifies a root-level filesystem.
FSRLRoot	getFS()	Returns the FSRLRoot object that represents the entire filesystem for this FSRL.
String	getName()	Always returns null for a FSRLRoot.
String	getPath()	Always returns null for a FSRLRoot.
String	getProtocol()	Returns the "protocol" portion of this FSRLRoot, for example, in a FSRLRoot of "file://", this method would return "file".
boolean	hasContainer()	Returns true if there is a parent containerfile, or false if this FSRLRoot specifies a root-level filesystem.
int	hashCode()
static FSRLRoot	makeRoot(String protocol)	Creates a FSRLRoot without a parent container, using the supplied protocol string as its type.
static FSRLRoot	nestedFS(FSRL containerFile, FSRLRoot copyFSRL)	Create a copy of copyFSRL, but using a different containerFile parent.
static FSRLRoot	nestedFS(FSRL containerFile, String fstype)	Creates a FSRLRoot as a child of a container FSRL, using the supplied protocol string as its type.
FSRL	withPathMD5(String newPath, String newMD5)	Creates a new FSRL as a child of this FSRLRoot, using the supplied path and MD5 values.

Method Details

makeRoot

public static FSRLRoot makeRoot(String protocol)

Creates a FSRLRoot without a parent container, using the supplied protocol string as its type.

Parameters:

protocol - string protocol name

Returns:

new FSRLRoot instance.

nestedFS

public static FSRLRoot nestedFS(FSRL containerFile,
 String fstype)

Creates a FSRLRoot as a child of a container FSRL, using the supplied protocol string as its type.

Parameters:

containerFile - FSRL of the container that contains this nested filesystem.

fstype - the filesystem type.

Returns:

new FSRLRoot instance with a parent pointing to the specified containerFile.

nestedFS

public static FSRLRoot nestedFS(FSRL containerFile,
 FSRLRoot copyFSRL)

Create a copy of copyFSRL, but using a different containerFile parent.

(ie. re-parents copyFSRL so its parent is containerFile)

Parameters:

containerFile - FSRL of new parent

copyFSRL - FSRLRoot that will be copied and re-parented.

Returns:

new FSRLRoot

getFS

public FSRLRoot getFS()

Description copied from class: FSRL

Returns the FSRLRoot object that represents the entire filesystem for this FSRL.

Never returns NULL, and calling getFS() on a FSRLRoot object returns itself.

Overrides:

getFS in class FSRL

Returns:

FSRLRoot instance that is the parent of this FSRL, never null.

getProtocol

public String getProtocol()

Returns the "protocol" portion of this FSRLRoot, for example, in a FSRLRoot of "file://", this method would return "file".

Returns:

string protocol / filesystem type.

getContainer

public FSRL getContainer()

Returns the parent containerfile FSRL, or null if this FSRLRoot specifies a root-level filesystem.

Returns:

FSRL of the container object that this filesystem is nested under.

hasContainer

public boolean hasContainer()

Returns true if there is a parent containerfile, or false if this FSRLRoot specifies a root-level filesystem.

Returns:

boolean true if this FSRLRoot has a parent container, or false if not.

getPath

public String getPath()

Always returns null for a FSRLRoot.

Overrides:

getPath in class FSRL

Returns:

null because this is a FSRLRoot instance which never has paths.

getName

public String getName()

Always returns null for a FSRLRoot.

Overrides:

getName in class FSRL

Returns:

null because this is a FSRLRoot instance which never has a path and therefore doesn't have a name part of a path.

withPathMD5

public FSRL withPathMD5(String newPath,
 String newMD5)

Creates a new FSRL as a child of this FSRLRoot, using the supplied path and MD5 values.

Parameters:

newPath - string path and filename of the object inside this filesystem, should not be null.

newMD5 - string md5 of the object inside this filesystem, null ok.

Returns:

new FSRL instance which is a child of this FSRLRoot.

appendToStringBuilder

protected void appendToStringBuilder(StringBuilder sb,
 boolean recurse,
 boolean includeParams,
 boolean includeFSRoot)

Overrides:

appendToStringBuilder in class FSRL

hashCode

public int hashCode()

Overrides:

hashCode in class FSRL
