Class ManualDependency

java.lang.Object
  jfun.yan.ManualDependency

All Implemented Interfaces:

java.io.Serializable, Dependency

public class ManualDependency
extends java.lang.Object
implements Dependency

ManualDependency disables auto-wiring by refusing to resolve any component part. When ManualDependency is used, all properties and parameters need to be explicitly specified using Component.withArgument(), Component.withArguments(), Component.withProperty() and Component.withProperties().

Method Detail

getArgument

public java.lang.Object getArgument(Signature src,
                                    int i,
                                    java.lang.Class type)

Description copied from interface: Dependency

Get an instance of an argument.

Specified by:

getArgument in interface Dependency

Parameters:

src - the signature of the function requesting this argument.

i - the ordinal position of the argument. Starting from 0.

type - the parameter type.

Returns:

the argument instance.

getProperty

public java.lang.Object getProperty(java.lang.Class component_type,
                                    java.lang.Object local_key,
                                    java.lang.Class type)

Description copied from interface: Dependency

Get an instance of a property.

Specified by:

getProperty in interface Dependency

Parameters:

component_type - the type of the component requesting the property.

local_key - the key of the property.

type - the property type.

Returns:

the property instance.

verifyArgument

public java.lang.Class verifyArgument(Signature src,
                                      int i,
                                      java.lang.Class type)

Description copied from interface: Dependency

Verifies that the argument instance can be resolved. The actual argument type is returned if verification succeeds.

Specified by:

verifyArgument in interface Dependency

Parameters:

src - the signature of the function requesting this argument.

i - the ordinal position of the argument. Starting from 0.

type - the parameter type.

Returns:

the actual type of the argument.
