Method Detail

implies

public boolean implies(ProtectionDomain pd)

Description copied from class: PermissionGrant

A DynamicPolicy implementation can use a PermissionGrant as a container for Dynamic Grant's. A PermissionGrant is first asked by the Policy if it applies to a Particular ProtectionDomain, if it does, the Policy calls getPermissions.

Specified by:

implies in class PermissionGrant

Parameters:

pd - ProtectionDomain

Returns:

true if implies.

RevocablePolicy

implies

public boolean implies(ClassLoader cl,
                       Principal[] pal)

Description copied from class: PermissionGrant

Checks if this PermissionGrant applies to the passed in ClassLoader and Principal's. Note that if this method returns false, it doesn't necessarily mean that the grant will not apply to the ClassLoader, since it will depend on the contents of the ClassLoader and that is indeterminate. It just indicates that the grant definitely does apply if it returns true. If this method returns false, follow up using the ProtectionDomain for a more specific test, which may return true.

implies in class PermissionGrant

implies

public boolean implies(CodeSource codeSource,
                       Principal[] pal)

Description copied from class: PermissionGrant

Specified by:

implies in class PermissionGrant

Returns:

true if implies.

isVoid

public boolean isVoid()

Description copied from class: PermissionGrant

Returns true if this PermissionGrant defines no Permissions, or if a PermissionGrant was made to a ProtectionDomain that no longer exists.

Specified by:

isVoid in class PermissionGrant

Returns:

true if void.

Returns:

PermissionGrantBuilder
