Method Detail

values

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

Returns:

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

valueOf

public static QualifyingStrategy valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

qualifies

abstract java.lang.annotation.Annotation qualifies(com.google.inject.Key<?> requirement,
                                                   com.google.inject.Binding<?> binding)

Attempts to qualify the given Binding against the requirement Key.

Parameters:

requirement - The requirement key

binding - The binding to qualify

Returns:

Qualifier annotation when the binding qualifies; otherwise null

selectFor

static final QualifyingStrategy selectFor(com.google.inject.Key<?> key)

Selects the appropriate qualifying strategy for the given requirement Key.

Parameters:

key - The requirement key

Returns:

Qualifying strategy

qualify

static final java.lang.annotation.Annotation qualify(com.google.inject.Key<?> key)

Computes a canonical Qualifier annotation for the given binding Key.

Parameters:

key - The key to qualify

Returns:

Qualifier for the key
