UnixResources (spf4j 8.5.26-SNAPSHOT API)

java.lang.Object
- java.lang.Enum<UnixResources>
- - org.spf4j.unix.UnixResources

All Implemented Interfaces:

Serializable, Comparable<UnixResources>
```
public enum UnixResources
extends Enum<UnixResources>
```
Possible values of the first parameter to getrlimit()/setrlimit() A combination of com.sun.jna.platform.unix.Resource and MACOSX resource.h this class requires jna-platforn which is a optional dependency.

  - RLIMIT_CPU
```
public static final UnixResources RLIMIT_CPU
```
    0 Per-process CPU limit, in seconds.
  - RLIMIT_FSIZE
```
public static final UnixResources RLIMIT_FSIZE
```
    1 Largest file that can be created, in bytes.
  - RLIMIT_DATA
```
public static final UnixResources RLIMIT_DATA
```
    2 Maximum size of data segment, in bytes.
  - RLIMIT_STACK
```
public static final UnixResources RLIMIT_STACK
```
    3 Maximum size of stack segment, in bytes.
  - RLIMIT_CORE
```
public static final UnixResources RLIMIT_CORE
```
    4 Largest core file that can be created, in bytes.
  - RLIMIT_RSS
```
public static final UnixResources RLIMIT_RSS
```
    5 Largest resident set size, in bytes. This affects swapping; processes that are exceeding their resident set size will be more likely to have physical memory taken from them.
  - RLIMIT_NPROC
```
public static final UnixResources RLIMIT_NPROC
```
    6 Number of processes.
  - RLIMIT_NOFILE
```
public static final UnixResources RLIMIT_NOFILE
```
    7 Number of open files.
  - RLIMIT_MEMLOCK
```

```
    8 Locked-in-memory address space.
  - RLIMIT_AS
```
public static final UnixResources RLIMIT_AS
```
    9 Address space limit.
  - RLIMIT_LOCKS

```
    10 Maximum number of file locks.
  - RLIMIT_SIGPENDING
```
public static final UnixResources RLIMIT_SIGPENDING
```
    11 Maximum number of pending signals.
  - RLIMIT_MSGQUEUE
```
public static final UnixResources RLIMIT_MSGQUEUE
```
    12 Maximum bytes in POSIX message queues.
  - RLIMIT_NICE
```
public static final UnixResources RLIMIT_NICE
```
    13 Maximum nice priority allowed to raise to. Nice levels 19 .. -20 correspond to 0 .. 39 values of this resource limit.
  - RLIMIT_RTPRIO
```
public static final UnixResources RLIMIT_RTPRIO
```
    14
  - RLIMIT_RTTIME
```
public static final UnixResources RLIMIT_RTTIME
```
    15 Maximum CPU time in microseconds that a process scheduled under a real-time scheduling policy may consume without making a blocking system call before being forcibly de-scheduled.
  - RLIMIT_NLIMITS
```
public static final UnixResources RLIMIT_NLIMITS
```
    16 Number of rlimit values
- Method Detail
  - values
```
public static UnixResources[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
```
for (UnixResources c : UnixResources.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static UnixResources valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - getMacId
```
public int getMacId()
```
  - getGnuId
```
public int getGnuId()
```
  - getSoftLimit
```
public long getSoftLimit()
                  throws UnixException
```
    Throws:
    
    UnixException
  - setSoftLimit
```
public void setSoftLimit(long limit)
                  throws UnixException
```
    Throws:
    
    UnixException
  - setLimits
```
public void setLimits(long softLimit,
                      long hardlimit)
               throws UnixException
```
    Throws:
    
    UnixException
  - getHardLimit
```
public long getHardLimit()
                  throws UnixException
```
    Throws:
