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

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)

Specified by:

hasAnnotation in interface IMapping

Parameters:

annotationType - The class of the annotation

Returns:

true if the annotation is defined on this type; false otherwise

isCollection

public boolean isCollection()
