Examples of SchemaDescriptor

com.cloudera.recordbreaker.analyzer.SchemaDescriptor
SchemaDescriptor is a container for schema-specific information. It can be implemented in several different ways, depending on whether the underlying file is a CSV, XML, a known Avro file, a synthetic Avro file, etc. @author "Michael Cafarella" @version 1.0 @since 1.0
org.apache.derby.iapi.sql.dictionary.SchemaDescriptor
This class represents a schema descriptor @version 0.1
org.codehaus.loom.components.util.info.SchemaDescriptor
A descriptor describing the schema to validate the components {@link org.apache.avalon.framework.parameters.Parameters} or {@link org.apache.avalon.framework.configuration.Configuration} object. If acomponent is neither {@link org.apache.avalon.framework.parameters.Parameterizable}nor {@link org.apache.avalon.framework.configuration.Configurable} then thisdescriptor will hold empty values for location, category and type.
Associated with each Schema is a set of arbitrary Attributes that can be used to store extra information about Schema requirements.
