# 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. Multivalued 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";
    };

- ## Constructor Details

  - ### 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 Details

  - ### 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`
