Enum Constant Details

UNKNOWN

public static final EProcessorArchitecture UNKNOWN

Unknown architecture - could not be determined.

ARCH_32

public static final EProcessorArchitecture ARCH_32

32 bit architecture.

ARCH_64

public static final EProcessorArchitecture ARCH_64

64 bit architecture.

Method Details

values

public static EProcessorArchitecture[] values()

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

Returns:

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

valueOf

public static EProcessorArchitecture 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

getBits

public int getBits()

Returns:

The number of bits of this architecture. May be CGlobal.ILLEGAL_UINT for the unknown architecture.

getBytes

public int getBytes()

Returns:

The number of bytes of this architecture (=bits/8). May be CGlobal.ILLEGAL_UINT for the unknown architecture.

getCurrentArchitectureBits

@CheckForSigned
public static int getCurrentArchitectureBits()

Returns:

The number of bits in the current architecture or CGlobal.ILLEGAL_UINT if this is undetermined.

forBits

@Nonnull
public static EProcessorArchitecture forBits(int nBits)

Get the processor architecture based on the passed number of bits.

Parameters:

nBits - The number of bits to get the processor architecture from.

Returns:

UNKNOWN if no processor architecture could be determined.

getCurrentArchitecture

@Nonnull
public static EProcessorArchitecture getCurrentArchitecture()

Returns:

The current processor architecture if running inside a Sun JVM. If no processor architecture could be determined, UNKNOWN is returned and never null.
