ErrorsProp

java.lang.Object
- com.iizix.prop.GProp<List<GError>>
- - com.iizix.prop.ErrorsProp

All Implemented Interfaces:

EventListener, IGProp<List<GError>>, Cloneable
```
public class ErrorsProp
extends GProp<List<GError>>
```
The errors property is used in the designer and files to store error and its values for a container. The container is e.g. a UI panel.
This property is private and is therefore not transmitted over transactions to a remote party.

- Constructor Detail
  - ErrorsProp
```
protected ErrorsProp()
```
    Creates an error array with no name and an empty synchronized ArrayList<GError> array.
  - ErrorsProp
```
public ErrorsProp(Atom propertyAtom)
```
    Creates an error array property with the specified name with an empty synchronized ArrayList<GError> array.
    
    Parameters:
    
    propertyAtom - the property atom.
  - ErrorsProp
```
public ErrorsProp(Atom propertyAtom,
                  List<GError> newValue)
           throws PropTypeException
```
    Creates an error array property with the specified name with an empty synchronized ArrayList<GError> array initialized with the specified errors.
    
    Parameters:
    
    propertyAtom - the property atom.
    
    newValue - the new error array value for the property.
    
    Throws:
    
    PropTypeException - If the property is read-only.
- Method Detail
  - getValueClasses
```
public Class<?>[] getValueClasses()
```
    Gets the list of possible native Java classes that can be used to set a value using setPropertyValue, in order of importance. Note that loss of precision in data if e.g. an Float property accepts a Double. However, the setPropertyValue throws IllegalArgumentException if the range in invalid, e.g. conversion of a Integer to a Byte, and the value is not -127 to 128.
    
    Specified by:
    
    getValueClasses in interface IGProp<List<GError>>
    
    Specified by:
    
    getValueClasses in class GProp<List<GError>>
    
    Returns:
    
    The array of Java classes that can be accepted in the setPropertyValue method. The first type is the "native" or most preferred type. The array is at least one item in length and never null.
  - clone
```
public ErrorsProp clone()
                 throws CloneNotSupportedException
```
    Creates a clone out of this property. The cloning is overridden by the subclasses in order to handle cloning of its class variables appropriately.
    Cloning is used for "virtualization" of a property tree in the server. Client property classes will therefore throw CloneNotSupportedException.
    Once a tree has been cloned, the change-flag is reset, and the create-flag is set. All listeners are also removed! The new cloned property is an orphan, i.e. has no parent set.
    Note that the cloning process is done WITHOUT thread synchronization for performance reasons, thus no modifications should be done to the tree!
    The ErrorProperty clones the ArrayList used for the items.
    
    Overrides:
    
    clone in class GProp<List<GError>>
    
    Throws:
    
    CloneNotSupportedException - If a subclass doesn't allow cloning, e.g. the client properties.
  - validatePropType
```
public void validatePropType(Object newValue)
                      throws PropTypeException
```
    Validates that the value to set is of List<?> instance. Later, when setting the property, the method modifyPropertyValue will be called, and this one will require the type List<GError> in order not to throw PropertyException.
    
    Specified by:
    
    validatePropType in interface IGProp<List<GError>>
    
    Specified by:
    
    validatePropType in class GProp<List<GError>>
    
    Parameters:
    
    newValue - The new value to set.
    
    Throws:
    
    PropTypeException - if newValue is not of List<?> instance.
  - modifyPropValue
```
protected int modifyPropValue(Object oldValue,
                              Object newValue,
                              PropMgr propMgr)
                       throws PropException
```
    Called when setting a new value for this property. This method is normally not overridden by subclasses, but e.g. for properties containing arrays, this may be handled here, in order not modify the "oldValue" (such as an array, but rather to change it with the data from the "newValue").
    
    Overrides:
    
    modifyPropValue in class GProp<List<GError>>
    
    Parameters:
    
    oldValue - The old value.
    
    newValue - The new value.
    
    propMgr - The property manager for remote change, null for local.
    
    Returns:
    
    1 for value has changed, 0 for same value as current value.
    
    Throws:
    
    PropException - when the new value doesn't validate correctly.
  - appendPropValue
```
protected void appendPropValue(PropMgr propertyManager,
                               Transaction trans,
                               Object value)
```
    Appends the error array to an outgoing transaction.
    
    Specified by:
    
    appendPropValue in class GProp<List<GError>>
    
    Parameters:
    
    propertyManager - the property manager instance.
    
    trans - transaction to append the properties to.
    
    value - the value to append to the transaction, a reference to the current property value.
  - initializeValue
```
public boolean initializeValue(PropMgr propertyManager,
                               Transaction trans)
```
    Initializes the property value from a transaction.
    
    Specified by:
    
    initializeValue in class GProp<List<GError>>
    
    Parameters:
    
    propertyManager - the property manager.
    
    trans - the transaction to initialize the property with.
    
    Returns:
    
    true if the value has changed, false otherwise.
  - initializeProp
```
public void initializeProp(Element element)
                    throws PropException
```
    Called to initialize the property from an Element. The property should initialize itself from attributes and nodes with appropriate information.
    
    Overrides:
    
    initializeProp in class GProp<List<GError>>
    
    Parameters:
    
    element - The Element.
    
    Throws:
    
    PropException - when the initialization fails.
  - sortList
```
public void sortList()
              throws PropTypeException
```
    Sorts the list according to the default JVM locale.
    
    Throws:
    
    PropTypeException - If the property is read-only.
  - initializeElement
```
public void initializeElement(Element element)
```
    Called when the XML file for the property tree is serialized from properties. The property should fill attributes and nodes with appropriate information.
    After the element, elements "error" builds up all entries containing the errors.
    
    Overrides:
    
    initializeElement in class GProp<List<GError>>
    
    Parameters:

public boolean hasError(GError error)
```
    Checks if an error already exists.
    
    Parameters:
    
    error - The error.
    
    Returns:
    
    true if the error is present, false otherwise.
  - removeError

    Returns:
    
    boolean, true if the was changed, false for no change.
    
    Throws:
    
    PropTypeException - If the property is read-only.
  - removeError
```
public GError removeError(int index)
                   throws PropTypeException
```
    Removes an error in the at a specific index.
    
    Parameters:
    
    index - the index in the array to remove.
    
    Returns:
    
    the error that was removed.
    
    Throws:
    
    PropTypeException - If the property is read-only.
  - getError
```
public GError getError(int index)

    the requested error at the specified index.
  - getArrayList
```
public List<GError> getArrayList()
```
    Gets the synchronized List<GError> of all errors. Be careful with manipulating the errors, because no changed-events are fired! They must explicitly be set using the setChanged method. Accessing the list directly is enabled for performance reasons only.
    
    Returns:
    
    The synchronized List<GError> if the property is not read-only, otherwise an unmodifiable synchronized List<GError>.
  - getPropValue0
```

                         throws Exception
```
    Tries conversion of possibly accepted properties values using the setPropertyValue method into the most preferred property value type. If the input value already is of the preferred type, the same object is returned.

    toNativeValue0 in class GProp<List<GError>>
    
    Parameters:
    
    value - The input value to convert to native value.

    Returns:
    
    The converted input value in the preferred property value object type.
    
    Throws:
    
    Exception - For conversion exceptions.
