Method Details

values

public static EJVMVendor[] 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 EJVMVendor 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

determineIfItIsCurrentJVMVendor

protected abstract boolean determineIfItIsCurrentJVMVendor()

isJVMVendor

public final boolean isJVMVendor()

isSun

public final boolean isSun()

Returns:

true if this is a Sun JVM (usually for Java ≤ 1.6).

isOracle

public final boolean isOracle()

Returns:

true if this is an Oracle JVM (for Java ≥ 1.7).

getCurrentVendor

@Nonnull
public static EJVMVendor getCurrentVendor()

Returns:

The current JVM vendor. If the vendor could not be determined, UNKNOWN is returned and never null.
