Method Detail

compileValue

public void compileValue(ICompilationContext ctxt,
                         Class<?> expectedType)
                  throws MRuleValidationException

Description copied from class: AbstractReadAccessor

Implementation to handle case when expected result is a single value.

Specified by:

compileValue in class AbstractReadAccessor

Throws:

MRuleValidationException

compileCollection

public <G,C extends Collection<G>> void compileCollection(ICompilationContext ctxt,
                                                          Class<C> expectedType,
                                                          Class<G> expectedGenericType)
                                                   throws MRuleValidationException

Unsupported.

Specified by:

compileCollection in class AbstractReadAccessor

Throws:

MRuleValidationException

getEstimatedReadCost

public CostInfo getEstimatedReadCost(ICompilationContext ctxt)
                              throws MRuleValidationException

Description copied from interface: IReadAccessor

Estimates the reading complexity, to allow callers to optimize calls. Calls to this method should be done on a compiled accessor, so that all information is available to compute complexity.
Calls to non-compiled instance may return non-accurate results.

Parameters:

ctxt - Compilation context.

Throws:

MRuleValidationException - if validation problem detected.

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

getType

public Class<?> getType(IContext ctxt)

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.

getGenericCollectionType

public Class<?> getGenericCollectionType(IContext ctxt)

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.

getImplementationId

public String getImplementationId()

Description copied from interface: IAddon

Unique addon implementation ID. In case of conflict, an Class Initialization error will be raised.

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.

toString

public void toString(OuterWithLevel outer)
              throws IOException

Description copied from interface: Outable

Method used to send String representation of the current object to the OuterWithLevel.

Throws:

IOException

isCacheUsed

public boolean isCacheUsed()

Description copied from class: AbstractAddon

Returns false by default.

Specified by:

isCacheUsed in interface IAddon

Overrides:

isCacheUsed in class AbstractAddon

clone

public MConditionsCountAccessor clone()

Description copied from interface: IAddon

Clones the Addon.
The general contract is that the clone of a compiled Addon is still compiled.

Specified by:

clone in interface IAccessor

Specified by:

clone in interface IReadAccessor

Specified by:

clone in interface IAddon

Specified by:

clone in interface IMRulesObject

Overrides:

clone in class AbstractReadAccessor

equals

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

getConditions

public List<ICondition> getConditions()

setConditions

public void setConditions(List<ICondition> conditions)

isConsiderValidated

public boolean isConsiderValidated()

setConsiderValidated

public void setConsiderValidated(boolean considerValidated)
