Method Detail

create

protected UCPServiceConfiguration create(Properties properties,
                                         System system,
                                         Properties coordinates)

Deprecated.

Overrides the UCPServiceConfigurationProvider.create(Properties, io.helidon.service.configuration.api.System, Properties) method to return a new UCPServiceConfigurationLocalhost instance when invoked.

This method never returns null.

Overrides of this method must not return null.

This method returns a new UCPServiceConfigurationLocalhost instance with each invocation.

Overrides of this method must return a new UCPServiceConfiguration implementation of some kind.

Overrides:

create in class UCPServiceConfigurationProvider

Parameters:

properties - a Properties instance that will be used as the basis of the UCPServiceConfigurationLocalhost implementation that will be returned; must not be null

system - a System determined to be in effect; may, strictly speaking, be null but ordinarily is non-null and enabled

coordinates - a Properties instance representing the meta-properties in effect; may be null

Returns:

a new UCPServiceConfigurationLocalhost instance; never null

Throws:

NullPointerException - if properties is null

appliesTo

protected boolean appliesTo(Properties properties,
                            System system,
                            Properties coordinates)

Deprecated.

Overrides the UCPServiceConfigurationProvider.appliesTo(Properties, io.helidon.service.configuration.api.System, Properties) method to return true if the supplied System is enabled and an instance of LocalhostSystem and if the UCPServiceConfigurationProvider.appliesTo(Properties, io.helidon.service.configuration.api.System, Properties) method returns true.

Overrides:

appliesTo in class UCPServiceConfigurationProvider

Parameters:

properties - a Properties instance that will be used as the basis of the UCPServiceConfigurationLocalhost implementation that will be returned by the create(Properties, io.helidon.service.configuration.api.System, Properties) method; must not be null

system - a System determined to be in effect; may, strictly speaking, be null but ordinarily is non-null and enabled

coordinates - a Properties instance representing the meta-properties in effect; may be null

Returns:

true if this UCPServiceConfigurationLocalhostProvider applies to the configuration space implied by the supplied parameters; false otherwise

installDataSourceProperties

protected void installDataSourceProperties(Properties target,
                                           System system,
                                           Properties coordinates,
                                           String dataSourceName)

Deprecated.

Overrides the UCPServiceConfigurationProvider.installDataSourceProperties(Properties, io.helidon.service.configuration.api.System, Properties, String) method to automatically create in-memory H2 databases as needed.

Specifically, this method:

1. Calls the UCPServiceConfigurationProvider.installDataSourceProperties(Properties, io.helidon.service.configuration.api.System, Properties, String) method with the supplied parameters.
2. Checks to see if a property named javax.sql.DataSource.dataSourceName .explicitlyConfigured has a String value equal to anything other than true, including null.
3. If so, then it sets certain properties on target as follows:
   1. javax.sql.DataSource. dataSourceName.dataSourceClassName = org.h2.jdbcx.JdbcDataSource
   2. javax.sql.DataSource. dataSourceName.dataSource.description = A local, transient, in-memory H2 database
   3. javax.sql.DataSource. dataSourceName.dataSource.user = sa
   4. javax.sql.DataSource. dataSourceName.dataSource.password =
   5. javax.sql.DataSource. dataSourceName.dataSourceUrl = jdbc:h2:mem:dataSourceName

Overrides:

installDataSourceProperties in class UCPServiceConfigurationProvider

Parameters:

target - a Properties instance that will be used as the basis of the UCPServiceConfigurationLocalhost implementation that will be returned by the create(Properties, io.helidon.service.configuration.api.System, Properties) method and into which properties may be installed; must not be null

system - a System determined to be in effect; may, strictly speaking, be null but ordinarily is non-null and enabled

coordinates - a Properties instance representing the meta-properties in effect; may be null

dataSourceName - the data source name in question; may be null

Throws:

NullPointerException - if target is null
