Constructor Detail
MultiProp
protected MultiProp()
Creates a color property with no name and with a null value.
MultiProp
public MultiProp(Atom propertyAtom)
Creates a color property with the specified name with a null value.- Parameters:
propertyAtom- the property atom.
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, thesetPropertyValuethrowsIllegalArgumentExceptionif the range in invalid, e.g. conversion of a Integer to a Byte, and the value is not -127 to 128.- Specified by:
getValueClassesin interfaceIGProp<VALUE>- Specified by:
getValueClassesin classGProp<java.lang.Object[]>- Returns:
- The array of Java classes that can be accepted in the
setPropertyValuemethod. The first type is the "native" or most preferred type. The array is at least one item in length and never null.
setup
protected final void setup(int count, java.lang.Class<?> valueClass)Sets up the property.- Parameters:
count- The count of values.valueClass- The class for the values.
modifyPropValue
protected int modifyPropValue(java.lang.Object oldValue, java.lang.Object newValue, PropMgr propMgr) throws PropExceptionCalled 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:
modifyPropValuein classGProp<java.lang.Object[]>- 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, -1 for not processed. 2 can also be returned to indicate the current value has been modified with new contents. This is e.g. the case for the StringMapProp.
- Throws:
PropException- when the new value doesn't validate correctly.
equalValues
protected java.lang.Object equalValues(GProp<?> compareTo, java.lang.Object[] thisValue, java.lang.Object[] compareValue, int how)
Checks for property value equality. The object is of the correct type for the respective property type. The Atoms and other properties such as Private/Extends has already been checked for equality or correctness.- Overrides:
equalValuesin classGProp<java.lang.Object[]>- Parameters:
compareTo- The comparing-to property that contains the value.thisValue- This property value (for synchronization reasons).compareValue- Another property value.how- Flags EQC_* values for equal checking.- Returns:
- The property not being equal, null for equal (both values null).
getValueCount
public int getValueCount()
Gets the value count.
validatePropType
public void validatePropType(java.lang.Object newValue) throws PropTypeExceptionValidates that the value to set is of GColor instance.Note: When this method is called, synchronization is done at the property itself, so no synchronization on the tree should be done.
- Specified by:
validatePropTypein interfaceIGProp<VALUE>- Specified by:

index- The index.- Returns:
- The property value, null if none has been set anywhere.
getRealPropValue
public VALUE getRealPropValue(int realIndex)
Gets the "real" indexed property value (default index=0, other indexes+1).- Parameters:
realIndex- The "real" index.- Returns:
- The property value or null for none.
setPropValueDefault

Sets the default value.- Parameters:
value- The new default value.- Returns:
- change-flag.

setPropValues
public boolean setPropValues(VALUE singleValue) throws PropException
Sets all property values at once to a single value. The default value is also set with this call.- Parameters:
singleValue- The single value to set for all values, including the default value.- Returns:
- The change-flag.
- Throws:
PropException- If value is not of correct type.
setPropValues
public boolean setPropValues(java.lang.Object[] values) throws PropExceptionSets all property values at once along with a default value.- Parameters:
values- The new values.- Returns:
- The change-flag.
