java.lang.Object | +--xjava.security.IJCE_SecuritySupport
This class is used to make any security checks needed by IJCE (for example when adding and removing security providers). It is needed to work around some nasty compatibility problems that would otherwise arise from supporting Java 1.0.2, Java 1.1 and Netscape simultaneously.

(package private) static void |
checkPrivilegeEnabled(java.lang.String targetname,
int depth)
On VMs that support Netscape's PrivilegeManager extensions, this checks that the security privilege with name targetname has been enabled. |
(package private) static void |
checkPrivilegeEnabled(Target target,
int depth)
On VMs that support Netscape's PrivilegeManager extensions, this checks that the privilege given by target has been enabled. |
(package private) static void |
checkPrivilegeEnabled(Target target,
java.lang.Object arg,
int depth)
On VMs that support Netscape's PrivilegeManager extensions, this checks that the privilege given by target, with parameter arg has been enabled. |
(package private) static void |
checkSystemCaller(int depth)
If a SecurityManager is installed, this method checks that there is no class loaded by a ClassLoader in the previous depth stack frames. |
(package private) static Target |
findTarget(java.lang.String name)
Returns a Target that can be passed to PrivilegeManager.enablePrivilege(...) , in order to request
permission for an action that requires the user's trust. |
(package private) static Target |
findTarget(java.lang.String name,
java.lang.Object arg)
Reserved for future use, in case parameterized targets are needed. |

static void checkPrivilegeEnabled(java.lang.String targetname, int depth)
IJCE_SecuritySupport.checkSystemCaller(depth)
.
For example,
IJCE_SecuritySupport.checkPrivilegeEnabled("AddSecurityProvider", 1)
On Netscape this will check that the "AddSecurityProvider" privilege has been enabled. On other VMs it will check that either no security manager is installed, or the immediate caller is a system class.
static void checkPrivilegeEnabled(Target target, int depth)
IJCE_SecuritySupport.checkSystemCaller(depth)
.
For example,
IJCE_SecuritySupport.checkPrivilegeEnabled(target, 1)
On Netscape this will check that the target privilege has been enabled. On other VMs it will check that either no security manager is installed, or the immediate caller is a system class.
static void checkPrivilegeEnabled(Target target, java.lang.Object arg, int depth)
IJCE_SecuritySupport.checkSystemCaller(depth)
.checkPrivilegeEnabled(netscape.security.Target, int)
static void checkSystemCaller(int depth)
For example,
IJCE_SecuritySupport.checkSystemCaller(1)
will check that either no security manager is installed, or the immediate caller is a system class.
