Field Detail

m_Value

protected Object m_Value

value of the property

m_PropertyClass

protected OwPropertyClass m_PropertyClass

class description of the property

Constructor Detail

OwStandardProperty

public OwStandardProperty(Object value_p,
                          OwPropertyClass propertyClass_p)

construct Property Object and set members

Method Detail

clone

public Object clone()

create a copy of the object

Specified by:

clone in interface OwProperty

Overrides:

clone in class Object

Returns:

OwProperty copy of this object

compareTo

public int compareTo(Object obj_p)

implementation of java.lang.Comparable interface Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object. In the foregoing description, the notation sgn(expression) designates the mathematical signum function, which is defined to return one of -1, 0, or 1 according to whether the value of expression is negative, zero or positive. The implementor must ensure sgn(x.compareTo(y)) == -sgn(y.compareTo(x)) for all x and y. (This implies that x.compareTo(y) must throw an exception iff y.compareTo(x) throws an exception.) The implementor must also ensure that the relation is transitive: (x.compareTo(y)>0 && y.compareTo(z)>0) implies x.compareTo(z)>0. Finally, the implementer must ensure that x.compareTo(y)==0 implies that sgn(x.compareTo(z)) == sgn(y.compareTo(z)), for all z. It is strongly recommended, but not strictly required that (x.compareTo(y)==0) == (x.equals(y)). Generally speaking, any class that implements the Comparable interface and violates this condition should clearly indicate this fact. The recommended language is "Note: this class has a natural ordering that is inconsistent with equals."

Specified by:

compareTo in interface Comparable

Parameters:

obj_p - the Object to be compared.

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

getPropertyClass

public OwPropertyClass getPropertyClass()
                                 throws Exception

get the class description of the property

Specified by:

getPropertyClass in interface OwProperty

Throws:

Exception

getFieldDefinition

public OwFieldDefinition getFieldDefinition()
                                     throws Exception

get the corresponding field definition of the field

Specified by:

getFieldDefinition in interface OwField

Returns:

OwFieldDefinition

Throws:

Exception

getValue

public Object getValue()
                throws Exception

get the value of the property. Can also be a list of values (see OwPropertyClass.isArray)

Specified by:

getValue in interface OwField

Returns:

Object value of property if property is scalar, or a java.io.List of objects if Property is an array

Throws:

Exception

setValue

public void setValue(Object oValue_p)
              throws Exception

set the value of the property. Can also be a list of values (see OwPropertyClass.isArray)

Specified by:

setValue in interface OwField

Parameters:

oValue_p - value of property if property is scalar, or a java.io.List of objects if Property is an array

Throws:

Exception

isReadOnly

public boolean isReadOnly(int iContext_p)
                   throws Exception

check if property is read only on the instance level NOTE: isReadOnly is also defined in OwPropertyClass on the class level. I.e. A Property might be defined as readable on the class level, but still be write protected on a specific instance.

Specified by:

isReadOnly in interface OwProperty

Parameters:

iContext_p - Context in which the property is read-only as defined by CONTEXT_...

Returns:

true if property is read only

Throws:

Exception

isHidden

public boolean isHidden(int iContext_p)
                 throws Exception

check if property is visible to the user

Specified by:

isHidden in interface OwProperty

Parameters:

iContext_p - Context in which the property is read-only as defined by CONTEXT_...

Returns:

true if property is visible to the user

Throws:

Exception

getNativeObject

public Object getNativeObject()
                       throws Exception

get the native object from the ECM system WARNING: The returned object is Opaque. Using the native object makes the client dependent on the ECM System

Specified by:

getNativeObject in interface OwProperty

Returns:

no native object available

Throws:

Exception

toString

public String toString()

Overrides:

toString in class Object
