        }
    } else {
        this.getProperties().putAll(source.getAllProperties());
    }
    return this;

Example 2 with IPropertyValueProxy

use of org.eclipse.elk.graph.properties.IPropertyValueProxy in project elk by eclipse.

the class EMapPropertyHolderImpl method getProperty.

/**
 * <!-- begin-user-doc -->
 * <!-- end-user-doc -->
 * @generated NOT
 */
@SuppressWarnings("unchecked")
public <T> T getProperty(IProperty<T> property) {
    Object value = getProperties().get(property);
    if (value instanceof IPropertyValueProxy) {

            return (T) value;
        }
    } else if (value != null) {
        return (T) value;
    }
    // the reason for the side effect below is that if a default value has been returned
    // and the object is altered by the user, the user expects the altered object to be
    // the value of the property in case he asks for the property again
    T defaultValue = property.getDefault();
    if (defaultValue instanceof Cloneable) {
        // We are now dealing with a clone of the default value which me may safely store away
        // for further modification
        setProperty(property, defaultValue);
    }
    return defaultValue;
}

Example 3 with IPropertyValueProxy

use of org.eclipse.elk.graph.properties.IPropertyValueProxy in project elk by eclipse.

the class EMapPropertyHolderImpl method getAllProperties.

/**

 */
public Map<IProperty<?>, Object> getAllProperties() {
    EMap<IProperty<?>, Object> props = getProperties();

            IPropertyValueProxy proxy = (IPropertyValueProxy) entry.getValue();
            // Try to resolve the proxy's value, maybe the layout option was
            // registered by now. If not, we preserve the proxy.
            Object value = proxy.resolveValue(entry.getKey());
            if (value != null) {
                entry.setValue(value);
            }
