Method Details
-
setRestrict
public void setRestrict(boolean restrict) Set the restrict attribute.- Parameters:
restrict
- the value to set.
-
isRestrict
public boolean isRestrict()Get the restrict attribute.- Returns:
- the restrict attribute.
-
setName
Set the definition's name.- Parameters:
name
- the name of the definition.
-
getName
-
setClass
Set the class of the definition. As a side-effect may set the classloader and classname.- Parameters:
clazz
- the class of this definition.
-
setClassName
Set the classname of the definition.- Parameters:
className
- the classname of this definition.
-
getClassName
Get the classname of the definition.- Returns:
- the name of the class of this definition.
-
setAdapterClass
Set the adapter class for this definition. This class is used to adapt the definitions class if required.- Parameters:
adapterClass
- the adapterClass.
-
setAdaptToClass
Set the assignable class for this definition.- Parameters:
adaptToClass
- the assignable class.
-
setClassLoader
Set the classloader to use to create an instance of the definition.- Parameters:
classLoader
- the ClassLoader.
-
getClassLoader
Get the classloader for this definition.- Returns:
- the classloader for this definition.
-
getExposedClass
Get the exposed class for this definition. This will be a proxy class (adapted class) if there is an adapter class and the definition class is not assignable from the assignable class.- Parameters:
project
- the current project.- Returns:
- the exposed class - may return null if unable to load the class
-
getTypeClass
-
innerGetTypeClass
Try and load a class, with no attempt to catch any fault.- Returns:
- the class that implements this component
- Throws:
ClassNotFoundException
- if the class cannot be found.NoClassDefFoundError
- if the there is an error finding the class.
-
create
-
checkClass
Checks if the attributes are correct.- if the class can be created.
- if an adapter class can be created
- if the type is assignable from adapter
- if the type can be used with the adapter class
- Parameters:
project
- the current project.
-
innerCreateAndSet
public <T> T innerCreateAndSet(Class<T> newclass, Project project) throws NoSuchMethodException, InstantiationException, IllegalAccessException, InvocationTargetException Inner implementation of thecreateAndSet(Project, Class)
logic, with no exception catching.- Type Parameters:
T
- return type of the method- Parameters:
newclass
- class to createproject
- the project to use- Returns:
- a newly constructed and bound instance.
- Throws:
NoSuchMethodException
- no good constructor.InstantiationException
- cannot initialize the object.IllegalAccessException
- cannot access the object.InvocationTargetException
- error in invocation.
-
sameDefinition
Equality method for this definition (assumes the names are the same).- Parameters:
other
- another definition.project
- the project the definition.- Returns:
- true if the definitions are the same.
-
similarDefinition
Similar definition; used to compare two definitions defined twice with the same name and the same types. The classloader may be different but have the same path so #sameDefinition cannot be used.- Parameters:
other
- the definition to compare to.project
- the current project.- Returns:
- true if the definitions are the same.
