Get the list of Files under the path. When the number of files is reached, the file list is send as non last message. When it is finished, the caller is responsable to send the last file list.

Parameters:
session 
lma is only use as a source to create a copy
path 
Returns:
the string containing triplet of index lid sid did of all files under the path

static String openlsd.network.server.legacy.LSDPathConstants.getListOfFilesInC ( IoSession  session,

) [static, private]

Get the list of Files under the path. When the number of files is reached, the file list is send as non last message. When it is finished, the caller is responsable to send the last file list.

Based on C program. Maybe slower than full JAVA.

Parameters:
session 
lma is only use as a source to create a copy
path 
Returns:
the string containing triplet of index lid sid did of all files under the path

static String openlsd.network.server.legacy.LSDPathConstants.getListOfFilesinJava ( IoSession  session,
LSDMsgAnswear  lma,
String  path 
) [static, private]

Get the list of Files under the path. When the number of files is reached, the file list is send as non last message. When it is finished, the caller is responsable to send the last file list.

Parameters:
session 
lma is only use as a source to create a copy
path 
Returns:
the string containing triplet of index lid sid did of all files under the path

static LSDStringList openlsd.network.server.legacy.LSDPathConstants.listRecursiveFileDir ( IoSession  session,
LSDMsgAnswear  lma,

LSDStringList  stringList 
) [static, protected]

Get recursively th list of files in the StringBuilder from the dir. When the maximum number of files is reached (LSDConstants.MAXIMUM_FILELIST), the file list is send as non last message. When it is finished, the caller is responsable to send the last file list. Used a recursive version.

Parameters:
session 
lma is only use as a source to create a copy
dir 
stringList 
Returns:
the LSDStringList which contains the StringBuilder with the list of file (sid did) and the number of files

static String openlsd.network.server.legacy.LSDPathConstants.getListOfFilesMD5 ( IoSession  session,
LSDMsgAnswear  lma,
String  path 
) [static]

Get the list of Files under the path. When the number of files is reached, the file list is send as non last message. When it is finished, the caller is responsable to send the last file list.

Parameters:
session 
lma is only use as a source to create a copy
path 
Returns:
the string containing triplet of index lid sid did of all files under the path and the associated MD5.

static LSDStringList openlsd.network.server.legacy.LSDPathConstants.listRecursiveFileDirMD5 ( IoSession  session,
LSDMsgAnswear  lma,
File  dirsource,
LSDStringList  stringList 
) [static, private]

Get the list of files in the StringBuilder from the dir and recursively. When the maximum number of files is reached (LSDConstants.MAXIMUM_FILELIST), the file list is send as non last message. When it is finished, the caller is responsable to send the last file list. This version does used a recursive algorithm.

Parameters:

lma is only use as a source to create a copy
dirsource 
stringList 
Returns:
the LSDStringList which contains the StringBuilder with the list of file (sid did md5) and the number of files
