PropertyUtil (Sitevision API)

```
@Requireable(value="PropertyUtil")
public interface PropertyUtil
```
Utility interface for getting Node property values.
An instance of the Sitevision class implementing this interface can be obtained via Utils.getPropertyUtil(). See Utils for how to obtain an instance of the Utils interface.

The advantage of using these methods instead of explicitly use the "get property" methods as defined in JCR is that none of the methods defined here throw Exceptions. (Exception handling can of course be handled properly if you implements your own JSR 286 portlet in Java, but when rendering in Velocity you can't catch Exceptions.)
---------------------------------------------------------
Example 1: You use Velocity and strongly suspect that a Node have a boolean property called "isInUse"
---------------------------------------------------------
1. The JCR way:

a) This can return true, false or throw an Exception:
```
   #if ($aNode.getProperty('isInUse').boolean)
     ...
   #end
```
b) Even if you ensure there actually are a property called "isInUse" it can still throw an Exception if the property isn't a boolean:
```
   #if ($aNode.hasProperty('isInUse') && $aNode.getProperty('isInUse').boolean)
     ...
   #end
```
c) Your best possible effort to avoid Exceptions is to ensure that there are a property and that it actually is of boolean type before you check its value:
(Note! Property types are defined in javax.jcr.PropertyType and the BOOLEAN type is represented by the int value 6):
```
   #if ($aNode.hasProperty('isInUse') && $aNode.getProperty('isInUse').type == 6 && $aNode.getProperty('isInUse').boolean)
     ...
   #end
```
The drawback with this alternative is that you miss boolean properties that isn't registered as the BOOLEAN type (e.g. a String property with the value "true" or "false")

2. The PropertyUtil way:

This always returns true or false:
```
   #set ($propertyUtil = $sitevisionUtils.propertyUtil)
   ...
   #if ($propertyUtil.getBoolean($aNode, 'isInUse')
     ...
   #end
```
---------------------------------------------------------
Example 2: You use Velocity and want to do an integer addition of a fixed int value and a int property "myNumber".
(Note! An addition in Velocity must be executed in a #set statement)
---------------------------------------------------------
1. The JCR way:

This can't be achieved in Velocity! You can only fetch the value as a long ($aNode.getProperty('myNumber').long) but Velocity needs an int or an Integer to perform addition.

2. The PropertyUtil way:

This will work in Velocity (i.e. use PropertyUtil to get the int):
```
   #set ($propertyUtil = $sitevisionUtils.propertyUtil)
   ...
   #set ($result = $propertyUtil.getInt($aNode, 'myNumber') + 45)
```
---------------------------------------------------------
Example 3: You use Velocity and want to get two int property values from a node and one of the property names contains illegal characters.
(Note! Illegal characters in node names and property names must always be escaped)
---------------------------------------------------------
Since the property name "anIllegal[./]name" contains illegal characters it must be escaped. To do this you typically use the escapeJcrName(String) method in EndecUtil. Note that the property name "aLegalName" is not escaped since it doesn't contain any illegal characters. For best performance - never escape a name if you are certain that it doesn't contain any illegal characters.
```
   #set ($propertyUtil = $sitevisionUtils.propertyUtil)
   #set ($endecUtil = $sitevisionUtils.endecUtil)
   ...
   #set ($escapedName = $endecUtil.escapeJcrName('anIllegal[./]name'))
   #set ($firstValue = $propertyUtil.getInt($aNode, $escapedName)

   #set ($secondValue = $propertyUtil.getInt($aNode, 'aLegalName')
 
```

```
String getNestedString(Node aNode,
 String aNodePropertyName,
 String aPropertyName)
```
 Gets a String property from a "nested" Node's property. (i.e. the base Node has a property that is a Node, and that "inner/nested" Node has a String property).
 Note! This method does not escape names (i.e. aNodePropertyName and aPropertyName). Illegal characters in node names and property names must always be escaped, typically via EndecUtil.escapeJcrName(String). For best performance - never escape a name if you are certain that it doesn't contain any illegal characters. Sitevision model properties never contain illegal characters. Though, depending on configuration "dynamic" ones (e.g. metadata properties) might contain illegal characters.
 
 Parameters:
 
 aNode - the base Node that has a property that is a Node
 
 aNodePropertyName - the name of the "inner/nested" Node that is a property on aNode
 
 aPropertyName - the name of the property for the "inner/nested" Node
 
 Returns:
 
 the value for aPropertyName as String. If no property exists, null is returned.

 Note! This method does not escape names (i.e. aNodePropertyName and aPropertyName). Illegal characters in node names and property names must always be escaped, typically via EndecUtil.escapeJcrName(String). For best performance - never escape a name if you are certain that it doesn't contain any illegal characters. Sitevision model properties never contain illegal characters. Though, depending on configuration "dynamic" ones (e.g. metadata properties) might contain illegal characters.
 
 Parameters:
 
 aNode - the base Node that has a property that is a Node
 
 aNodePropertyName - the name of the "inner/nested" Node that is a property on aNode
 
 aPropertyName - the name of the Binary property for the "inner/nested" Node
 
 Returns:
 
 the value for aPropertyName as Binary. If no property exists or it isn't a Binary, null is returned.

```
 Gets a List of XML escaped property values from a Node.
 This is a convenience method for getting a list of property values that also should be XML escaped. Strings that should be included in the html output should typically always be XML escaped to be valid XHTML and avoid XSS problems.
 
 This Velocity code:
```
 #set ($endecUtil = ...)
 #set ($propertyUtil = ...)
 ...
 #set ($valueList = $propertyUtil.getStrings($myNode, 'aProperty'))
 <ul>
 #foreach ($value in $valueList)
 <li>
 $endecUtil.escapeXML($value)
 </li>
 #end
 </ul>
 
```
 would typically be replaced with this:
```
 #set ($propertyUtil = ...)
 ...
 #set ($escapedValueList = $propertyUtil.getStringsEscaped($myNode, 'aProperty'))
 <ul>
 #foreach ($escapedValue in $escapedValueList)
 <li>
 $escapedValue
 </li>
 #end
 </ul>
 
```
 Note! This method does not escape the property name (i.e. aPropertyName). Illegal characters in node names and property names must always be escaped, typically via EndecUtil.escapeJcrName(String). For best performance - never escape a name if you are certain that it doesn't contain any illegal characters. Sitevision model properties never contain illegal characters. Though, depending on configuration "dynamic" ones (e.g. metadata properties) might contain illegal characters.
 Parameters:
 
 aNode - the Node that has a property
 
 aPropertyName - the name of the property
 
 Returns:
 
 the string value(s) for aPropertyName, XML escaped and embedded in a List. If no property exists, null is returned.

 aPropertyName - the name of the property
 
 aDefaultValue - fallback list if no value exists. Note! The actual fallback list is never returned but it's values might be used.

 the string value(s) for aPropertyName, XML escaped and embedded in a List. If no property exists, aDefaultValue is returned.

 Parameters:
 
 aNode - the base Node that has a property that is a Node

 aPropertyName - the name of the property for the "inner/nested" Node
 
 Returns:
 
 the string value(s) for aPropertyName as a List. If no property exists, null is returned.

 - hasProperty
```
boolean hasProperty(Node aNode,
 String aPropertyName)
```
 Whether a Node has a property or not.
 This is a lenient method for checking if a property exists on a Node without having to catch a potential exception from JCR. This method is typically more efficient than its JCR counterpart Node.hasProperty(String) method.
 
 Note! This method does not escape the property name (i.e. aPropertyName). Illegal characters in node names and property names must always be escaped, typically via EndecUtil.escapeJcrName(String). For best performance - never escape a name if you are certain that it doesn't contain any illegal characters. Sitevision model properties never contain illegal characters. Though, depending on configuration "dynamic" ones (e.g. metadata properties) might contain illegal characters.
 
 Parameters:
 
 aNode - the Node to check for the property
 
 aPropertyName - name of the property to check for
 
 Returns:
 
 true if aNode has a property with the name aPropertyName, false otherwise. Returns false if aNode is null or if aPropertyName is null or whitespace-only.
