                                         ZenPropertyManager

    ZenPropertyManager adds keyedselection type to PropertyManager.
    A keyedselection displayes a different name in the popup then
    the actual value the popup will have.

    It also has management for zenProperties which are properties that can be
    inherited long the acquision chain.  All properties are for a branch are
    defined on a "root node" specified by the function which must be returned
    by the function getZenRootNode that should be over ridden in a sub class.
    Prperties can then be added further "down" the aq_chain by calling
    setZenProperty on any contained node.

    ZenProperties all have the same prefix which is defined by iszprop
    this can be overridden in a subclass.

    ZenPropertyManager overrides getProperty and getPropertyType from
    PropertyManager to support acquisition. If you want to query an object
    about a property, but do not want it to search the acquistion chain then
    use the super classes method or aq_base.  Example:

        # acquires property from dmd.Devices
        dmd.Devices.Server.getProperty('zCollectorPlugins')

        # does not acquire property from dmd.Devices
        PropertyManager.getProperty(dmd.Devices.Server, 'zCollectorPlugins')

        # also does not acquire property from dmd.Devices
        aq_base(dmd.Devices.Server).getProperty('zSnmpCommunity')

    The properties are stored as attributes which is convenient, but can be
    confusing.  Attribute access always uses acquistion.  Setting an
    attribute, will not add it to the list of properties, so subsquent calls
    to hasProperty or getProperty won't return it.

    Property Transformers are stored at dmd.propertyTransformers and transform
    the property based on type during calls to the _setProperty,
    _updateProperty, and getProperty methods. Adding a property using
    _setProperty applies the appropriate transformer and adds its value as an
    attribute, but when you access it as an attribute the property transformer
    is again applied, but this time using its transformForGet method.

Method Details | [hide private]

### _setPropValue(self, id, value) | source code
override from PerpertyManager to handle checks and ip creation Overrides: OFS.PropertyManager.PropertyManager._setPropValue

### _setProperty(self, id, value, type='string', label=None, visible=True, setter=None) | source code
for selection and multiple selection properties the value argument indicates the select variable of the property Overrides: OFS.PropertyManager.PropertyManager._setProperty

### _updateProperty(self, id, value) | source code
This method sets a property on a zope object. It overrides the method in PropertyManager. If Zope is upgraded you will need to check that this method has not changed! It is overridden so that we can catch the ValueError returned from the field2* converters in the class Converters.py Overrides: OFS.PropertyManager.PropertyManager._updateProperty

### manage_editProperties(self, REQUEST) | source code
Edit object properties via the web. The purpose of this method is to change all property values, even those not listed in REQUEST; otherwise checkboxes that get turned off will be ignored. Use manage_changeProperties() instead for most situations. Overrides: OFS.PropertyManager.PropertyManager.manage_editProperties

### zenPropertyIds(self, all=True, pfilt=iszprop) | source code
Return list of device tree property names. If all use list from property root node.

### _findParentWithProperty(self, id) | source code
Returns self or the first acquisition parent that has a property with the id. Returns None if no parent had the id.

### hasProperty(self, id, useAcquisition=False) | source code
Override method in PropertyManager to support acquisition. Overrides: OFS.PropertyManager.PropertyManager.hasProperty

### getProperty(self, id, d=None) | source code
Get property value and apply transformer. Overrides method in Zope's PropertyManager class. Acquire values from aquisiton parents if needed. Overrides: OFS.PropertyManager.PropertyManager.getProperty

### getPropertyType(self, id) | source code
Overrides methods from PropertyManager to support acquistion. Overrides: OFS.PropertyManager.PropertyManager.getPropertyType

### getZ(self, id) | source code
Return the value of a zProperty on this object. This method is used to lookup zProperties for a user with a role that doesn't have direct access to an attribute further up the acquisition path. If the requested property is a password, then None is returned. Parameters: `id` (string) - id of zProperty Returns: Value of zProperty Permission: ZEN_ZPROPERTIES_VIEW

    161
    >>> dmd.Devices.getZ('zWinPassword')
