Class FontPermission

  • All Implemented Interfaces:
    Serializable, Guard
    public class FontPermission
extends Permission
    This class is for font permissions.

    The name is related to the font APIs and it symbolizes the permission's action.

    The meaning of the possible permissions is defined as follows:

    add
    add permission. Permission is checked when fonts are added to the system during the initialization process.
    Since:
    2.0

    • Constructor Detail

      • FontPermission

        public FontPermission​(String permission)
        Creates a permission with the specified name.
        Parameters:
        permission - the name of the FontPermission.

    • Method Detail

      • equals

        public boolean equals​(@Nullable
                      Object obj)
        Description copied from class: Permission
        Checks two Permission objects for equality.

        Do not use the equals method for making access control decisions; use the implies method.

        Specified by:
        equals in class Permission
        Parameters:
        obj - the object we are testing for equality with this object.
        Returns:
        true if both Permission objects are equivalent.

      • getActions

        public String getActions()
        Description copied from class: Permission
        Returns the actions as a String. This is abstract so subclasses can defer creating a String representation until one is needed. Subclasses should always return actions in what they consider to be their canonical form. For example, two FilePermission objects created via the following: 
         perm1 = new FilePermission(p1, "read,write");
 perm2 = new FilePermission(p2, "write,read");
        both return "read,write" when the getActions method is invoked.
        Specified by:
        getActions in class Permission
        Returns:
        the actions of this Permission.

      • hashCode

        public int hashCode()
        Description copied from class: Permission
        Returns the hash code value for this Permission object.

        The required hashCode behavior for Permission Objects is the following:

        • Whenever it is invoked on the same Permission object more than once during an execution of a Java application, the hashCode method must consistently return the same integer. This integer need not remain consistent from one execution of an application to another execution of the same application.
        • If two Permission objects are equal according to the equals method, then calling the hashCode method on each of the two Permission objects must produce the same integer result.
        Specified by:
        hashCode in class Permission
        Returns:
        a hash code value for this object.
        See Also:
        Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

      • implies

        public boolean implies​(Permission permission)
        Description copied from class: Permission
        Checks if the specified permission's actions are "implied by" this object's actions.

        This must be implemented by subclasses of Permission, as they are the only ones that can impose semantics on a Permission object.

        Specified by:
        implies in class Permission
        Parameters:
        permission - the permission to check against.
        Returns:
        true if the specified permission is implied by this object, false if not.
