    • Method Detail

      • compareTo

        public int compareTo​(IMapping mapping)
        Specified by:
        compareTo in interface java.lang.Comparable<IMapping>

      • getMappingType

        public int getMappingType()
        Returns the type of this mapping.
        Specified by:
        getMappingType in interface IMapping
        Returns:
        One of the supported mapping type, which is one of the constants defined in IMappingType when the provider only supports generic JPA

      • getName

        public java.lang.String getName()
        Returns the name of the persistence property represented by this mapping.
        Specified by:
        getName in interface IMapping
        Returns:
        The name of this mapping

      • getParent

        public IManagedType getParent()
        Returns the parent managed type owning this mapping.
        Specified by:
        getParent in interface IMapping
        Returns:
        The parent of this mapping

      • getType

        public IType getType()
        Returns the type of this mapping. If this mapping is a relationship mapping, the parameter type of the collection is returned.

        @OneToMany
        private Collection<Employee> employees;

        "Employee" is the type. To retrieve Collection, IMapping.getTypeDeclaration() needs to be used, its type will be Collection and it's generic type will be Employee.

        Specified by:
        getType in interface IMapping
        Returns:
        The external form representing the type of this mapping

      • getTypeDeclaration

        public ITypeDeclaration getTypeDeclaration()
        Returns the declaration of the Java class, which gives the information about type parameters, dimensionality, etc.

        @OneToMany
        private Collection<Employee> employees;

        "Collection<Employee>" is the type declaration.

        Specified by:
        getTypeDeclaration in interface IMapping
        Returns:
        The external form of the class' type declaration

      • hasAnnotation

        public boolean hasAnnotation​(java.lang.Class<? extends java.lang.annotation.Annotation> annotationType)
