## Class DomainLoadStoreParameter

- java.lang.Object
- - java.security.DomainLoadStoreParameter

- All Implemented Interfaces:
    KeyStore.LoadStoreParameter

      public final class DomainLoadStoreParameter
      extends Object
      implements KeyStore.LoadStoreParameter

  Configuration data that specifies the keystores in a keystore domain. A keystore domain is a collection of keystores that are presented as a single logical keystore. The configuration data is used during `KeyStore` `load` and `store` operations.

  The following syntax is supported for configuration data:

           domain <domainName> [<property> ...] {
               keystore <keystoreName> [<property> ...] ;
               ...
           };
           ...

  where `domainName` and `keystoreName` are identifiers and `property` is a key/value pairing. The key and value are separated by an 'equals' symbol and the value is enclosed in double quotes. A property value may be either a printable string or a binary string of colon-separated pairs of hexadecimal digits. Multi-valued properties are represented as a comma-separated list of values, enclosed in square brackets. See `Arrays.toString(java.lang.Object[])`.

  To ensure that keystore entries are uniquely identified, each entry's alias is prefixed by its `keystoreName` followed by the entry name separator and each `keystoreName` must be unique within its domain. Entry name prefixes are omitted when storing a keystore.

  Properties are context-sensitive: properties that apply to all the keystores in a domain are located in the domain clause, and properties that apply only to a specific keystore are located in that keystore's clause. Unless otherwise specified, a property in a keystore clause overrides a property of the same name in the domain clause. All property names are case-insensitive. The following properties are supported:

  `keystoreType="<type>"`
    The keystore type.
  `keystoreURI="<url>"`
    The keystore location.
  `keystoreProviderName="<name>"`
    The name of the keystore's JCE provider.
  `keystorePasswordEnv="<environment-variable>"`
    The environment variable that stores a keystore password. Alternatively, passwords may be supplied to the constructor method in a `Map<String, ProtectionParameter>`.
  `entryNameSeparator="<separator>"`
    The separator between a keystore name prefix and an entry name. When specified, it applies to all the entries in a domain. Its default value is a space.

  For example, configuration data for a simple keystore domain comprising three keystores is shown below:

       domain app1 {
           keystore app1-truststore
               keystoreURI="file:///app1/etc/truststore.jks";

           keystore system-truststore
               keystoreURI="${java.home}/lib/security/cacerts";

           keystore app1-keystore
               keystoreType="PKCS12"
               keystoreURI="file:///app1/etc/keystore.p12";
       };

    Constructors
    Constructor and Description
    `DomainLoadStoreParameter(URI configuration, Map<String,KeyStore.ProtectionParameter> protectionParams)` Constructs a DomainLoadStoreParameter for a keystore domain with the parameters used to protect keystore data.

  - ### Method Summary

    All Methods Instance Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `URI` | `getConfiguration()` Gets the identifier for the domain configuration data.
    `KeyStore.ProtectionParameter` | `getProtectionParameter()` Gets the keystore protection parameters for this domain.
    `Map<String,KeyStore.ProtectionParameter>` | `getProtectionParams()` Gets the keystore protection parameters for keystores in this domain.

- - ### Constructor Detail

    - #### DomainLoadStoreParameter

          public DomainLoadStoreParameter(URI configuration,
                                          Map<String,KeyStore.ProtectionParameter> protectionParams)

      Constructs a DomainLoadStoreParameter for a keystore domain with the parameters used to protect keystore data.
      Parameters:
        `configuration` - identifier for the domain configuration data. The name of the target domain should be specified in the `java.net.URI` fragment component when it is necessary to distinguish between several domain configurations at the same location.
        `protectionParams` - the map from keystore name to the parameter used to protect keystore data. A `java.util.Collections.EMPTY_MAP` should be used when protection parameters are not required or when they have been specified by properties in the domain configuration data. It is cloned to prevent subsequent modification.
      Throws:
        `NullPointerException` - if `configuration` or `protectionParams` is `null`

  - ### Method Detail

    - #### getConfiguration

          public URI getConfiguration()

      Gets the identifier for the domain configuration data.
      Returns:
        the identifier for the configuration data

    - #### getProtectionParams

          public Map<String,KeyStore.ProtectionParameter> getProtectionParams()

      Gets the keystore protection parameters for keystores in this domain.
      Returns:
        an unmodifiable map of keystore names to protection parameters

    - #### getProtectionParameter

          public KeyStore.ProtectionParameter getProtectionParameter()

      Gets the keystore protection parameters for this domain. Keystore domains do not support a protection parameter.
      Specified by:
        `getProtectionParameter` in interface `KeyStore.LoadStoreParameter`
      Returns:
        always returns `null`
