Method Details

values

public static CSPDirective[] values()

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

Returns:

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

valueOf

public static CSPDirective valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null

getValue

public String getValue()

checkValueForDirective

public void checkValueForDirective(CSPRenderable value,
 List<CSPRenderable> existingDirectiveValues)

Check if value can be added to the list of other values. By default, it checks for conflicts with wildcards and none and it checks if values are valid uris.

Parameters:

value - The value to add.

existingDirectiveValues - The other values.

Throws:

IllegalArgumentException - if the given value is invalid.

fromValue

public static CSPDirective fromValue(String value)

Returns:

The CSPDirective constant whose value-parameter equals the input-parameter or null if none can be found.
