Method Detail

values

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

Returns:

valueOf

public static StandardSystemProperty 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

key

public String key()

Returns the key used to lookup this system property.

value

public String value()

Returns the current value for this system property by delegating to System.getProperty(String).

toString

public String toString()

Returns a string representation of this system property.

Overrides:

toString in class Enum<StandardSystemProperty>

Returns:

the name of this enum constant
