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, java.util.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 java.lang.Class<?>[] getValueClasses()
Gets the list of possible native Java classes that can be used to set a value usingsetPropertyValue
, in order of importance. Note that loss of precision in data if e.g. an Float property accepts a Double. However, thesetPropertyValue
throwsIllegalArgumentException
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 interfaceIGProp<java.util.List<GError>>
- Specified by:
getValueClasses
in classGProp<java.util.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 java.lang.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.
validatePropType
public void validatePropType(java.lang.Object newValue) throws PropTypeException
Validates that the value to set is ofList<?>
instance. Later, when setting the property, the methodmodifyPropertyValue
will be called, and this one will require the typeList<GError>
in order not to throwPropertyException
.- Specified by:
validatePropType
in interfaceIGProp<java.util.List<GError>>
- Specified by:
validatePropType
in classGProp<java.util.List<GError>>
- Parameters:
newValue
- The new value to set.- Throws:
PropTypeException
- ifnewValue
is not ofList<?>
instance.
modifyPropValue
protected int modifyPropValue(java.lang.Object oldValue, java.lang.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 classGProp<java.util.List<GError>>
- Parameters:
oldValue
- The old value.newValue
- The new value.propMgr
- The property manager for remote change, null for local.- Returns:
- 0 for same value as current value, 2 to indicate the current value has been modified with new contents.
- Throws:
PropException
- when the new value doesn't validate correctly.
appendPropValue
protected void appendPropValue(PropMgr propertyManager, SendTransaction trans, java.lang.Object value)
Appends the error array to an outgoing transaction.- Specified by:
appendPropValue
in classGProp<java.util.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, ReadTransaction trans)
Initializes the property value from a transaction.- Specified by:
initializeValue
in classGProp<java.util.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(org.w3c.dom.Element element) throws PropException
Called to initialize the property from anElement
. The property should initialize itself from attributes and nodes with appropriate information.- Overrides:
initializeProp
in classGProp<java.util.List<GError>>
- Parameters:
element
- TheElement
.- 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(org.w3c.dom.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 classGProp<java.util.List<GError>>
- Parameters:
element
- TheElement
.
addError
public void addError(GError e) throws PropTypeException
Adds a error to the array.- Parameters:
e
- the error to add.- Throws:
PropTypeException
- If the property is read-only.
addErrors
public void addErrors(java.util.List<GError> newList) throws PropTypeException
Adds all errors from a list.- Parameters:
newList
- the list of new errors to add.- Throws:
PropTypeException
- If the property is read-only.
addErrors
public void addErrors(GError[] errors) throws PropTypeException
Adds all errors from an array.- Parameters:
errors
- the array of new errors to add.- Throws:
PropTypeException
- If the property is read-only.
hasError
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
public boolean removeError(GError error)
Removes a particular error.- Returns:
- true for success, false if error is not found.
size
public int size()
Gets the error count in the array.- Returns:
- int, the error count.
clear
public boolean clear() throws PropTypeException
Removes all errors from the array.- 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:

- the error that was removed.
- Throws:
PropTypeException
- If the property is read-only.
getError
public GError getError(int index)
Gets an error from a specific index in the array.- Parameters:
index
- the index of the error.- Returns:
- the requested error at the specified index.
getArrayList
public java.util.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 thesetChanged
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 synchronizedList<GError>
.
getPropValue0
protected java.lang.Object getPropValue0(java.lang.Object value, int index) throws java.lang.Exception
Gets the property value in another class form than the "native" one. This method tries conversion of a "native" property value into another class type. This method is used when filling in a POJO variable (Plain Old Java Object Field) from a "native" property value.- Specified by:
getPropValue0
in classGProp<java.util.List<GError>>
- Parameters:
value
- The property value.index
- The index in the Class array returned bygetValueClasses()

- The property value in the requested class, after conversion.
- Throws:
java.lang.Exception
- Other exceptions that could occur.
toNativeValue0
protected java.lang.Object toNativeValue0(java.lang.Object value, int index) throws java.lang.Exception
Tries conversion of possibly accepted properties values using thesetPropertyValue
method into the most preferred property value type. If the input value already is of the preferred type, the same object is returned.- Specified by:

value
- The input value to convert to native value.index
- The index in the array returned bygetValueClasses()
, or -1 if not found.- Returns:
- The converted input value in the preferred property value object type.
