Methods

accept (line 34)

Accepts a visitor for this Parameter

The method is normally called by visiting a component adapter, that cascades the visitor also down to all its Parameters.

void accept (Xyster_Container_Visitor $visitor)

isResolvable (line 46)

Check if the Parameter can statisfy the expected type using the container.

boolean isResolvable (Xyster_Container_Interface $container, [Xyster_Container_Adapter $adapter = null], $expectedType, Xyster_Container_NameBinding $expectedNameBinding, boolean $useNames)

Xyster_Container_Interface $container: the container from which dependencies are resolved.
Xyster_Container_Adapter $adapter: the adapter that is asking for the instance
Xyster_Type $expectedType: the required type
Xyster_Container_NameBinding $expectedNameBinding: the expected parameter name
boolean $useNames

resolveInstance (line 59)

Retrieve the object from the Parameter that statisfies the expected type.

return: the instance or
1. null
if no suitable instance can be found.
throws: Xyster_Container_Exception if a referenced component could not be instantiated.

mixed resolveInstance (Xyster_Container_Interface $container, [Xyster_Container_Adapter $adapter = null], $expectedType, Xyster_Container_NameBinding $expectedNameBinding, boolean $useNames)

Xyster_Container_Interface $container: the container from which dependencies are resolved.
Xyster_Container_Adapter $adapter: the Component Adapter that is asking for the instance
Xyster_Type $expectedType: the required type
Xyster_Container_NameBinding $expectedNameBinding: the expected parameter name
boolean $useNames

verify (line 71)

Verify that the Parameter can statisfied the expected type using the container

throws: Xyster_Container_Exception if parameter and its dependencies cannot be resolved

void verify (Xyster_Container_Interface $container, [Xyster_Container_Adapter $adapter = null], $expectedType, Xyster_Container_NameBinding $expectedNameBinding, boolean $useNames)

Xyster_Container_Interface $container: the container from which dependencies are resolved.
Xyster_Container_Adapter $adapter: the Component Adapter that is asking for the verification
Xyster_Type $expectedType: the required type
Xyster_Container_NameBinding $expectedNameBinding: the expected parameter name
boolean $useNames
