SUMMARY: INNER | FIELD | CONSTR | METHOD | DETAIL: FIELD | CONSTR | METHOD |
Extends PRNGState to provide methods for obtaining and setting state details for PRNG's that can represent thier state as a sequence of ints.
The main purpose for this is to allow the state to be "passed between" objects using CORBA without defining a new IDL interface to get access to the actual state details.
This interface should not be used to change the state of a
PRNG! To enforce this restriction, the
setPRNGIntState requires a hash
parameter that should be used to verify that the state has not been
modified.
Method Summary | |
int[] |
getIntegerState()
Return an array of ints that fully captures the state of the PRNG represented by this PRNGState. |
int[] |
getIntegerStateHash()
Return the hash value for the state of the PRNG represented by this PRNGState. |
void |
setIntegerState(int[] intState,
int[] hash)
Set the internal state using an array of ints provided by another PRNGIntegerState . |

Method Detail |
public int[] getIntegerState()
public int[] getIntegerStateHash()
This hash value must be included as a parameter when the
setPRNGIntegerState
function is called, allowing it to
verify that the state has been correctly transmitted and is
has not been modified.
public void setIntegerState(int[] intState, int[] hash)
PRNGIntegerState
.
The hash
parameter allows the method to check that
the state provided has been correctly transmitted and has not
been modified.
