Enum ProcessorArchitecture

java.lang.Object

java.lang.Enum<ProcessorArchitecture>

org.apache.flink.util.ProcessorArchitecture

All Implemented Interfaces:

Serializable, Comparable<ProcessorArchitecture>

public enum ProcessorArchitecture
extends Enum<ProcessorArchitecture>

The processor architecture of the this system.

Note that the memory address size might be different than the actual hardware architecture, due to the installed OS (32bit OS) or when installing a 32 bit JRE in a 64 bit OS.

Enum Constant Detail

X86

public static final ProcessorArchitecture X86

The Intel x86 processor architecture.

AMD64

public static final ProcessorArchitecture AMD64

The AMD 64 bit processor architecture.

ARMv7

public static final ProcessorArchitecture ARMv7

The ARM 32 bit processor architecture.

AARCH64

public static final ProcessorArchitecture AARCH64

The 64 bit ARM processor architecture.

PPC64_LE

public static final ProcessorArchitecture PPC64_LE

The little-endian mode of the 64 bit Power-PC architecture.

UNKNOWN

public static final ProcessorArchitecture UNKNOWN

Unknown architecture, could not be determined. This one conservatively assumes 32 bit, because 64 bit platforms typically support 32 bit memory spaces.

Method Detail

values

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

Returns:

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

valueOf

public static ProcessorArchitecture 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

getAddressSize

public ProcessorArchitecture.MemoryAddressSize getAddressSize()

Gets the address size of the memory (32 bit, 64 bit).

getArchitectureName

public String getArchitectureName()

Gets the primary name of the processor architecture. The primary name would for example be "x86" or "amd64".

getAlternativeNames

public List<String> getAlternativeNames()

Gets the alternative names for the processor architecture. Alternative names are for example "i586" for "x86", or "x86_64" for "amd64".

getProcessorArchitecture

public static ProcessorArchitecture getProcessorArchitecture()

Gets the ProcessorArchitecture of the system running this process.

getMemoryAddressSize

public static ProcessorArchitecture.MemoryAddressSize getMemoryAddressSize()

Gets the MemorySize of the ProcessorArchitecture of this process.

Note that the memory address size might be different than the actual hardware architecture, due to the installed OS (32bit OS) or when installing a 32 bit JRE in a 64 bit OS.
