public void accept(IManagedTypeVisitor visitor)

Implements org.eclipse.persistence.jpa.jpql.tools.spi.IManagedType.accept.

Doc from org.eclipse.persistence.jpa.jpql.tools.spi.IManagedType.accept.

Visits this managed type with the given visitor.

Parameters
visitor:IManagedTypeVisitor

The visitor to visit this managed type object

compareToback to summary
public int compareTo(IManagedType managedType)

Implements java.lang.Comparable.compareTo.

Doc from java.lang.Comparable.compareTo.

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

The implementor must ensure signum(x.compareTo(y)) == -signum(y.compareTo(x)) for all x and y. (This implies that x.compareTo(y) must throw an exception if and only if y.compareTo(x) throws an exception.)

The implementor must also ensure that the relation is transitive: (x.compareTo(y) > 0 && y.compareTo(z) > 0) implies x.compareTo(z) > 0.

Finally, the implementor must ensure that x.compareTo(y)==0 implies that signum(x.compareTo(z)) == signum(y.compareTo(z)), for all z.

Parameters
managedType:IManagedType

the object to be compared.

Returns:int

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Returns the IMapping with the given name.

Parameters
