Examples with InternalConfiguration org.apache.ignite.configuration.annotation.InternalConfiguration used on opensource projects

Example 1 with InternalConfiguration

use of org.apache.ignite.configuration.annotation.InternalConfiguration in project ignite-3 by apache.

the class ConfigurationAsmGenerator method compileRootSchema.

/**
 * Generates, defines, loads and initializes all dynamic classes required for the given configuration schema.
 *
 * @param rootSchemaClass             Class of the root configuration schema.
 * @param internalSchemaExtensions    Internal extensions ({@link InternalConfiguration}) of configuration schemas ({@link
 *                                    ConfigurationRoot} and {@link Config}). Mapping: original schema -> extensions.
 * @param polymorphicSchemaExtensions Polymorphic extensions ({@link PolymorphicConfigInstance}) of configuration schemas ({@link
 *                                    PolymorphicConfig}). Mapping: original schema -> extensions.
