internalCompileValue

protected abstract void internalCompileValue(ICompilationContext ctxt,
                                             IProperty2 compiledProperty)

                                             UtilsException

Final compilation steps should be implemented here.

Throws:

MRuleValidationException

UtilsException

internalGet

protected Object internalGet(IExecutionContext ctxt)
                      throws MAccessorException

Description copied from class: AbstractReadAccessor

Specific addon implementation must be here.

Specified by:

internalGet in class AbstractReadAccessor

Throws:

MAccessorException

internalGet

protected abstract Boolean internalGet(IExecutionContext ctxt,
                                       IProperty2 compiledProperty)
                                throws MAccessorException,
                                       UtilsException

The final implementation should check the property here.

Throws:

MAccessorException

UtilsException

getType

public Class<?> getType(IContext ctxt)
                 throws MAccessorException

Description copied from interface: IAccessor

Returns the value's class, evaluated :

• at compilation time for standard compilation
• at runtime for light compilation

or null if the type can't be resolved.

Throws:

MAccessorException

getGenericCollectionType

public Class<?> getGenericCollectionType(IContext ctxt)
                                  throws MAccessorException

Description copied from interface: IAccessor

Returns the Generic type, if value is a collection or an array, evaluated :

• at compilation time for standard compilation
• at runtime for light compilation and execution phase

or null if the type can't be resolved or value is not a collection.

Throws:

MAccessorException

isShouldIterate

public boolean isShouldIterate()

Description copied from interface: IReadAccessor

If this iterator is dedicated to iterate over values, then it should be precised. In this case, the "get" method should return an Iterator, of instances of "getType".
Non-read only accessors should not be iterable. BUT it's not mandatory. In this particular case, the "set" method should be described precisely ...
Please not that returned Iterators should not support the "remove" method.
They also should use MRuleInternalRuntimeException if Exception must be thrown.
This method is not dependent on the compilation process. it can be called before and will return the correct result.
