@DefaultKey(value="config")
public class SkinConfigTool
extends org.apache.velocity.tools.generic.SafeConfig

An Apache Velocity tool that simplifies retrieval of custom configuration values for a Maven Site.

The tool is configured to access Maven site configuration of a skin inside <custom> element of site descriptor. It supports global properties (defined at skin level) and per-page properties (defined in <page><mypage> element). The per-page properties override the global ones.

A sample configuration would be like that:

 <custom>
   <reflowSkin>
     <prop1>value1</prop1>
     <prop2>
       <prop21>value2</prop21>
     </prop2>
     <pages>
       <mypage project="myproject">
         <prop1>override value1</prop1>
       </mypage>
     </pages>
   </reflowSkin>
 </custom>
 
 

To get the value of prop1, one would simply use $config.prop1. This would return "override value1". Then $config.prop2 would return "value2" - the global value.

The tool allows querying the value easily, falling back from page to global configuration to null, if none is available. It also provides convenience accessors for common values.

Method Detail

configure

protected void configure(org.apache.velocity.tools.generic.ValueParser values)

Overrides:

configure in class org.apache.velocity.tools.generic.SafeConfig

See Also:

SafeConfig.configure(ValueParser)

setKey

protected void setKey(String key)

Sets the key under which this tool has been configured.

Since:

1.0

getKey

public String getKey()

Should return the key under which this tool has been configured. The default is `config`.

Since:

1.0

get

public org.codehaus.plexus.util.xml.Xpp3Dom get(String property)

Default accessor for config properties. Instead of using $config.get("myproperty"), one can utilise Velocity fallback onto the default getter and use $config.myproperty.

Parameters:

property - the property of interest

Returns:

configuration node if found in the following sequence:

1. In page configuration
2. In global configuration
3. null otherwise

Since:

1.0

value

public String value(String property)

Retrieves the text value of the given property, e.g. as in <myprop>value</myprop>.

Parameters:

property - the property of interest

Returns:

the configuration value if found in page or globally, null otherwise.

Since:

1.0

See Also:

get(String)

is

public boolean is(String property)

A convenience method to check if the value of the property is "true".

Parameters:

property - the property of interest

Returns:

true if the configuration value is set either in page or globally, and is equal to "true".

Since:

1.0

See Also:

get(String)

not

public boolean not(String property)

A convenience method to check if the value of the property is "false". Useful for properties that are enabled by default - checks if the property is set to "false" explicitly.

Parameters:

property - the property of interest

Returns:

true if the configuration value is set either in page or globally, and is equal to "false". Note that this will return false if property is not set at all.

isValue

public boolean isValue(String property,
              String value)

A convenience method to check if the property is set to a specific value.

Parameters:

property - the property of interest

value - the property value to check

Returns:

true if the configuration value is set either in page or globally, and is equal to value.
