IImsConfigpublic interface IImsConfig implements android.os.IInterface| Provides APIs to get/set the IMS service capability/parameters.
The parameters can be configured by operator and/or user.
We define 4 storage locations for the IMS config items:
1) Default config:For factory out device or device after factory data reset,
the default config is used to build the initial state of the master config value.
2) Provisioned value: as the parameters provisioned by operator need to be preserved
across FDR(factory data reset)/BOTA(over the air software upgrade), the operator
provisioned items should be stored in memory location preserved across FDR/BOTA.
3) Master value: as the provisioned value can override the user setting,
and the master config are used by IMS stack. They should be stored in the
storage based on IMS vendor implementations.
4) User setting: For items can be changed by both user/operator, the user
setting should take effect in some cases. So the user setting should be stored in
database like setting.db.
Priority consideration if both operator/user can config the same item:
1) For feature config items, the master value is obtained from the provisioned value
masks with the user setting. Specifically the provisioned values overrides
the user setting if feature is provisioned off. Otherwise, user setting takes
effect.
2) For non-feature config item: to be implemented based on cases.
Special cases considered as below:
1) Factory out device, the master configuration is built from default config.
2) For Factory data reset/SW upgrade device, the master config is built by
taking provisioned value overriding default config.

| Methods Summary |
|---|
| public void | getFeatureValue(int feature, int network, com.android.ims.ImsConfigListener listener)Gets the value of the specified IMS feature item for specified network type.
This operation gets the feature config value from the master storage (i.e. final
value). Asynchronous non-blocking call.
| | public java.lang.String | getProvisionedStringValue(int item)Gets the value for ims service/capabilities parameters from the provisioned
value storage. Synchronous blocking call.
| | public int | getProvisionedValue(int item)Gets the value for ims service/capabilities parameters from the provisioned
value storage. Synchronous blocking call.
| | public boolean | getVolteProvisioned()Gets the value for IMS volte provisioned.
This should be the same as the operator provisioned value if applies.
| | public void | setFeatureValue(int feature, int network, int value, com.android.ims.ImsConfigListener listener)Sets the value for IMS feature item for specified network type.
This operation stores the user setting in setting db from which master db
is dervied.
| | public int | setProvisionedStringValue(int item, java.lang.String value)Sets the value for IMS service/capabilities parameters by the operator device
management entity. It sets the config item value in the provisioned storage
from which the master value is derived. Synchronous blocking call.
| | public int | setProvisionedValue(int item, int value)Sets the value for IMS service/capabilities parameters by the operator device
management entity. It sets the config item value in the provisioned storage
from which the master value is derived. Synchronous blocking call.
