Enum OSXJNAAffinity

java.lang.Object

java.lang.Enum<OSXJNAAffinity>

net.openhft.affinity.impl.OSXJNAAffinity

All Implemented Interfaces:

Serializable, Comparable<OSXJNAAffinity>, IAffinity

public enum OSXJNAAffinity
extends Enum<OSXJNAAffinity>
implements IAffinity

This is essentially the same as the NullAffinity implementation but with concrete support for getThreadId().

Method Detail

values

public static OSXJNAAffinity[] 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 (OSXJNAAffinity c : OSXJNAAffinity.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static OSXJNAAffinity 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

getAffinity

public BitSet getAffinity()

Specified by:

getAffinity in interface IAffinity

Returns:

returns affinity mask for current thread, or null if unknown

setAffinity

public void setAffinity(BitSet affinity)

Specified by:

setAffinity in interface IAffinity

Parameters:

affinity - sets affinity mask of current thread to specified value

getCpu

public int getCpu()

Specified by:

getCpu in interface IAffinity

Returns:

the current cpu id, or -1 if unknown.

getProcessId

public int getProcessId()

Specified by:

getProcessId in interface IAffinity

Returns:

the process id of the current process.

getThreadId

public int getThreadId()

Specified by:

getThreadId in interface IAffinity

Returns:

the thread id of the current thread or -1 is not available.
