Method Detail

getPermissions

public PermissionCollection getPermissions(CodeSource codesource)

Evaluates the global policy and returns a PermissionCollection object specifying the set of permissions allowed for code from the specified code source.

Overrides:

getPermissions in class Policy

Parameters:

codesource - the CodeSource associated with the caller. This encapsulates the original location of the code (where the code came from) and the public key(s) of its signer.

Returns:

the set of permissions allowed for code from codesource according to the policy.The returned set of permissions must be a new mutable instance and it must support heterogeneous Permission types.

getPermissions

public PermissionCollection getPermissions(ProtectionDomain domain)

Evaluates the global policy and returns a PermissionCollection object specifying the set of permissions allowed given the characteristics of the protection domain.

Overrides:

getPermissions in class Policy

Parameters:

domain - the ProtectionDomain associated with the caller.

Returns:

the set of permissions allowed for the domain according to the policy.The returned set of permissions must be a new mutable instance and it must support heterogeneous Permission types.

Since:

1.4

ProtectionDomain, SecureClassLoader

implies

public boolean implies(ProtectionDomain domain,
                       Permission permission)

Evaluates the global policy for the permissions granted to the ProtectionDomain and tests whether the permission is granted.

Overrides:

implies in class Policy

Parameters:

domain - the ProtectionDomain to test

permission - the Permission object to be tested for implication.

Returns:

true if "permission" is a proper subset of a permission granted to this ProtectionDomain.

Since:

1.4

See Also:

ProtectionDomain

refresh

public void refresh()

Refreshes/reloads the policy configuration. The behavior of this method depends on the implementation. For example, calling refresh on a file-based policy will cause the file to be re-read.

Overrides:

refresh in class Policy
