getSecurityPolicyID

public java.lang.Integer getSecurityPolicyID(java.lang.String policyName)
                                      throws java.io.IOException

This method fetches the security policy ID for the given security policy name from the locally-cached securityPolicyNameToIdMap_. If not found in the map, it fetchees it from the JNI MapClient cache. If no valid policy ID is returned by this method, it is safe to assume that the policy has not been created in the policy domain.

Parameters:

policyName - Security Policy name tag for which ID is required

Returns:

Security Policy ID

Throws:

java.io.IOException

getSecurityPolicyName

public java.lang.String getSecurityPolicyName(java.lang.Integer policyID)
                                       throws java.io.IOException

This method fetches the security policy name for the given security policy ID from the locally-cached securityPolicyIdToNameMap_. If not found in the map, it fetchees it from the JNI MapClient cache. If no valid policy name is returned by this method, it is safe to assume that the policy has not been created in the policy domain.

Parameters:

policyID - Security Policy ID tag for which nmae is required

Returns:

Security Policy Name

Throws:

java.io.IOException
