org.apache.cocoon.components.modules.input
Class ProjectPathModule

java.lang.Object
  org.apache.avalon.framework.logger.AbstractLogEnabled
      org.apache.cocoon.components.modules.input.AbstractInputModule
          org.apache.cocoon.components.modules.input.ProjectPathModule

All Implemented Interfaces:

Disposable, Component, Configurable, LogEnabled, ThreadSafe, InputModule

public class ProjectPathModule
extends AbstractInputModule
implements ThreadSafe

ProjectPathModule provides relative and absolute paths with regards to the root of a project.

Config:

    <component-instance logger="core.modules.input"
           name="myproject"
           class="org.apache.cocoon.components.modules.input.ProjectPathModule">
          <uri-prefix>my/project/</uri-prefix>
    </component-instance>
 

Usage:

    <map:transform src="skins/{forrest:skin}/xslt/fo/document2html.xsl">
       <map:parameter name="base" value="{myproject:relative}"/>
    </map:transform>

And then prepend this to all image paths:

  ...
  <xsl:param name="base"/>
  ...
  <xsl:template match="img">
      <img src="{concat($base, @src)}" ...
      ...
  </xsl:template>
  

Then if you are in my/project/some/folder/page.html, the image will have a relative path bact to the root of the project.

   <img src="../../imagename.png"/>
 

Using 'myproject:path' would have given you: /some/folder/page.html
Using 'myproject:folder' would have given you: /some/folder/

Method Detail

configure

public void configure(Configuration conf)
               throws ConfigurationException

Description copied from class: AbstractInputModule

Configures the database access helper. Takes all elements nested in component declaration and stores them as key-value pairs in settings. Nested configuration option are not catered for. This way global configuration options can be used. For nested configurations override this function.

Specified by:

configure in interface Configurable

Overrides:

configure in class AbstractInputModule

Throws:

ConfigurationException

See Also:

Configurable.configure(org.apache.avalon.framework.configuration.Configuration)

getAttribute

public Object getAttribute(String name,
                           Configuration modeConf,
                           Map objectModel)
                    throws ConfigurationException

Description copied from interface: InputModule

Standard access to an attribute's value. If more than one value exists, the first is returned. If the value does not exist, null is returned. To get all values, use InputModule.getAttributeValues(String, Configuration, Map) or InputModule.getAttributeNames(Configuration, Map) and InputModule.getAttribute(String, Configuration, Map) to get them one by one.

Specified by:

getAttribute in interface InputModule

Overrides:

getAttribute in class AbstractInputModule

Parameters:

name - a String that specifies what the caller thinks would identify an attribute. This is mainly a fallback if no modeConf is present.

modeConf - column's mode configuration from resource description. This argument is optional.

Throws:

ConfigurationException

See Also:

InputModule.getAttribute(java.lang.String, org.apache.avalon.framework.configuration.Configuration, java.util.Map)

getAttributeNames

public Iterator getAttributeNames(Configuration modeConf,
                                  Map objectModel)
                           throws ConfigurationException

Description copied from interface: InputModule

Returns an Iterator of String objects containing the names of the attributes available. If no attributes are available, the method returns an empty Iterator.

Specified by:

getAttributeNames in interface InputModule

Overrides:

getAttributeNames in class AbstractInputModule

Parameters:

modeConf - column's mode configuration from resource description. This argument is optional.

Throws:

ConfigurationException

See Also:

InputModule.getAttributeNames(org.apache.avalon.framework.configuration.Configuration, java.util.Map)

getAttributeValues

public Object[] getAttributeValues(String name,
                                   Configuration modeConf,
                                   Map objectModel)
                            throws ConfigurationException

Description copied from interface: InputModule

Returns an array of String objects containing all of the values the given attribute has, or null if the attribute does not exist. As an alternative, InputModule.getAttributeNames(Configuration, Map) together with InputModule.getAttribute(String, Configuration, Map) can be used to get the values one by one.

Specified by:

getAttributeValues in interface InputModule

Overrides:

getAttributeValues in class AbstractInputModule

Parameters:

name - a String that specifies what the caller thinks would identify an attributes. This is mainly a fallback if no modeConf is present.

modeConf - column's mode configuration from resource description. This argument is optional.

Throws:

ConfigurationException
