Constructor Detail
ByteArrayProp
protected ByteArrayProp()
Creates a byte array property with the specified name with a null value.
ByteArrayProp
public ByteArrayProp(Atom propertyAtom)
Creates a byte array property with the specified name with a null value.- Parameters:
propertyAtom
- the property atom.
ByteArrayProp
public ByteArrayProp(Atom propertyAtom, byte[] newValue)
Creates a byte property with the specified name with and value.- Parameters:
propertyAtom
- the property atom.newValue
- the new Font value for the property.
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<byte[]>
- Specified by:
getValueClasses
in classGProp<byte[]>
- 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 ByteArrayProp clone()
Clones the byte array property.
setPropValue
public boolean setPropValue(byte[] newValue)
Sets a new value for this property. If any listener is present and the value has changed compare to the last value, the listener is informed.- Parameters:
newValue
- the new value.- Returns:
- boolean true for value has changed, false for same value as current value.
getByteArray
public byte[] getByteArray()
Gets the byte array value. (For JavaScript this would not be relevant, but rather to return either a String in one method and an Array in another).- Returns:
- the byte array or null if no value is set.
validatePropType
public void validatePropType(java.lang.Object newValue) throws PropTypeException
Validates that the value to set is of Font 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:
validatePropType
in interfaceIGProp<byte[]>
- Specified by:
validatePropType
in classGProp<byte[]>
- Parameters:
newValue
- The new value to set.- Throws:
PropTypeException
- when the new value isn't of the correct class.
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<byte[]>
- 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.
appendPropValue
protected void appendPropValue(PropMgr propertyManager, SendTransaction trans, java.lang.Object value)
Appends the byte array property value. If uninitialized,false
is appended.- Specified by:
appendPropValue
in classGProp<byte[]>
- 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) throws PropException
Initializes the property value from a transaction.- Specified by:
initializeValue
in classGProp<byte[]>
- Parameters:
propertyManager
- the property manager.trans
- the transaction to initialize the property with.- Returns:
- true if the value has changed, false otherwise.
- Throws:
PropException
fromElementString
public java.lang.Object fromElementString(java.lang.String str) throws PropException
Called from theinitializeProperty(Element element)
method once the element String is retrieved from the "value" attribute.The string is the hexadecimal code for the byte array. White spaces are allowed, but not within pairs of hexadecimal values.
- Specified by:
fromElementString
in interfaceIGProp<byte[]>
- Overrides:
fromElementString
in classGProp<byte[]>
- Parameters:
str
- the String value of the object from the value attribute.- Returns:
- the returned byte array.
- Throws:
PropException
- When the
toElementString
public java.lang.String toElementString(java.lang.Object value)
Called from theinitializeElement(Element element)
method. Override this method to provide the appropriateObject
toString
conversion.The return string is the hexadecimal code for the byte array. White spaces ([CR]+LF) are allowed and are placed at every 80th character, but not within pairs of hexadecimal values.
- Specified by:
toElementString
in interfaceIGProp<byte[]>
- Overrides:
toElementString
in classGProp<byte[]>
- Parameters:
value
- the value in the object to convert to a string.- Returns:
- the string corresponding to the object value.
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<byte[]>
- Parameters:
value
- The property value.index
- The index in the Class array returned bygetValueClasses()
.- Returns:
- 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:
toNativeValue0
in classGProp<byte[]>
- Parameters:
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.
- Throws:
java.lang.Exception
- For conversion exceptions.
