Enum Constant Detail

PARENT_FIRST

public static final ClassLoaderLookupStrategy PARENT_FIRST

Class will be looked up from the parent classloader first. If the class is found, then it will be returned. Otherwise lookup process will continue on the child classloader. If the class is found, then it will be returned, otherwise a ClassNotFoundException will be thrown.

PARENT_ONLY

public static final ClassLoaderLookupStrategy PARENT_ONLY

Class will be looked up from the parent classloader only. If the class is found, then it will be returned, otherwise a ClassNotFoundException will be thrown.

CHILD_FIRST

public static final ClassLoaderLookupStrategy CHILD_FIRST

Class will be looked up from the child classloader first. If the class is found, then it will be returned. Otherwise lookup process will continue on the parent classloader. If the class is found, then it will be returned, otherwise a ClassNotFoundException will be thrown.

CHILD_ONLY

public static final ClassLoaderLookupStrategy CHILD_ONLY

Class will be looked up from the child classloader only. If the class is found, then it will be returned, otherwise a ClassNotFoundException will be thrown.

Method Detail

values

public static ClassLoaderLookupStrategy[] 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 (ClassLoaderLookupStrategy c : ClassLoaderLookupStrategy.values())
    System.out.println(c);

Returns:

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

valueOf

public static ClassLoaderLookupStrategy 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
