scalation
package scalation
The scalation
package specifies system-wide constants for directory paths.
Sub-packages may wish to define 'BASE-DIR = DATA_DIR + ⁄ + <package>' in their
own 'package.scala' files. For maintainability, directory paths should only
be specified in 'package.scala' files.

val
BASE: String
Base directory for ScalaTion (pick one, comment out the rest) Under module differentiated, each module (scalation_mathstat, scalation_modeling and scalation_models) will have its own base directory, rather than sharing a common base directory.
-
val
DATA_DIR: String
File system path for input/output data directory Use 'SCALATION_HOME' environment variable or else BASE directory "."
-
val
LOG_DIR: String
File system path for log (log/file output) directory Use 'SCALATION_HOME' environment variable or else BASE directory "."
-
val
MEM_MAPPED_DIR: String
File system path for memory mapped files directory Use 'SCALATION_HOME' environment variable or else BASE directory "."
-
val
SEP: String
The file path separation character: '/' for Linux/Mac, '\' for Windows Use either 'SEP' or '⁄' for portability, i.e., do not use '/' or '\'.
-
val
SRC_DIR: String
File system path for src (source code) directory Use 'SCALATION_HOME' environment variable or else BASE directory "."
- val SRC_SCALA_DIR: String
-
val
STORE_DIR: String
File system path for database storage directory Use 'SCALATION_HOME' environment variable or else BASE directory "."
-
def
removeLast(s: String): String
Remove the last path element from the file/directory pathname.
Remove the last path element from the file/directory pathname.
- s
the string to be so truncated

def
setParallelism[A](n: Int)(block: ⇒ A): A
Set the default parallelism level (number of threads to use) for an arbitrary block of code: 'parallel (n) { block }' when running parallel tasks.
Set the default parallelism level (number of threads to use) for an arbitrary block of code: 'parallel (n) { block }' when running parallel tasks. Then restore the old parallelism level.
