FilePermission
public FilePermission(String pathExpression,
String actionsString) Create a new FilePermission.
pathExpression - an expression specifying the paths this
permission represents.actionsString - a comma-separated list of the actions this
permission represents. The actions must be "read", "write",
"execute" and/or "delete".
equals
public boolean equals(Object o)
Check two FilePermissions for semantic equality.
Two FilePermissions are exactly equivalent if they have identical path
expressions and have exactly the same access permissions.
- equals in interface Permission
o - the Object to compare to.
- whether the Objects are semantically equivalent.
getActions
public String getActions()
Get the actions this FilePermission supports.
- getActions in interface Permission
- the String representing the actions this FilePermission supports.
hashCode
public int hashCode()
Get the hash code for this Object.
FilePermission's hash code is calculated as the exclusive or of the
target
String's hash code and the action String's hash code.
- hashCode in interface Permission
- the hash code for this Object.
implies
public boolean implies(Permission p)
Check to see if this permission implies another.
Permission A implies permission B if these things are all true:
- A and B are both FilePermissions.
- All possible files in B are included in A
(possibly more are in A).
- All actions B supports, A also supports.
- implies in interface Permission
p - the Permission to compare against.
- whether this Permission implies p
