Method Detail

values

public static ORMPlatform[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ORMPlatform c : ORMPlatform.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ORMPlatform valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getDelegates

public List<String> getDelegates()

EntitManager delegates class names

Returns:

Delegates class names

detectFromClasspath

public static ORMPlatform detectFromClasspath()
                                       throws IllegalStateException

Try to detect ORM platform to use form classpath

Returns:

Detected ORMPlatform, or null if not found

Throws:

IllegalStateException - If more than one ORM provide is found in classpath

resolve

public static ORMPlatform resolve(javax.persistence.EntityManager em)

Determines the ORMPlatform from the given EntityManager

Parameters:

em - EntityManager (must be not null)

Returns:

Resolved ORMPlatform. If none of know platforms match, null is returned
