Class MetadataSources

  • All Implemented Interfaces:
    Serializable
    public class MetadataSources
extends Object
implements Serializable
    Entry point for working with sources of O/R mapping metadata, either in the form of annotated classes, or as XML mapping documents.

    Note that XML mappings may be expressed using the JPA orm.xml format, or in Hibernate's legacy .hbm.xml format.

    An instance of MetadataSources may be obtained simply by instantiation, using new MetadataSources(). The client must register sources and then call buildMetadata(), or use getMetadataBuilder() to customize how the sources are processed (by registering naming strategies, etc).

    As an alternative to working directly with MetadataSources, and Metadata, a program may use Configuration.

        Read mappings from a particular XML file.

      • addCacheableFile

        public MetadataSources addCacheableFile​(File file)
        Add a cached mapping file. A cached file is a serialized representation of the DOM structure of a particular mapping. It is saved from a previous call as a file with the name {xmlFile}.bin where {xmlFile} is the name of the original mapping file.

        If a cached {xmlFile}.bin exists and is newer than {xmlFile}, the {xmlFile}.bin file will be read directly. Otherwise {xmlFile} is read and then serialized to {xmlFile}.bin for use the next time.

        Parameters:
        file - The cacheable mapping file to be added, {xmlFile} in above discussion.
        Returns:
        this (for method chaining purposes)

      • addCacheableFile

        public MetadataSources addCacheableFile​(File file,
                                        File cacheDirectory)
        Add a cached mapping file. A cached file is a serialized representation of the DOM structure of a particular mapping. It is saved from a previous call as a file with the name {xmlFile}.bin where {xmlFile} is the name of the original mapping file.

        If a cached {xmlFile}.bin exists and is newer than {xmlFile}, the {xmlFile}.bin file will be read directly. Otherwise {xmlFile} is read and then serialized to {xmlFile}.bin for use the next time.

        Parameters:
        file - The cacheable mapping file to be added, {xmlFile} in above discussion.
        Returns:
        this (for method chaining purposes)
