## org.eclipse.pde.ui.templates
Class OptionTemplateSection

    java.lang.Object
      org.eclipse.pde.ui.templates.AbstractTemplateSection
          org.eclipse.pde.ui.templates.BaseOptionTemplateSection
              org.eclipse.pde.ui.templates.OptionTemplateSection

All Implemented Interfaces:
  ITemplateSection, IVariableProvider

public abstract class OptionTemplateSection
extends BaseOptionTemplateSection

This class adds some conventions to the class it is based on. For example, it expects to find the template content in the following location:

         [install location]/[templateDirectory]/[sectionId]

where `templateDirectory` is expected to be 'templates_3.0' (to distinguish from template designed for earlier Eclipse versions), and `sectionId` is the unique identifier as reported by the template section.

It also assumes that all wizard pages associated with this template will be based on `OptionWizardTemplatePage`.

Since:
  2.0
See Also:
  `OptionWizardTemplatePage`

Constructor Detail

### OptionTemplateSection

    public OptionTemplateSection()

  The default constructor.

Method Detail

### getSectionId

    public abstract String getSectionId()

  Returns the unique name of this section. This name will be used to construct name and description lookup keys, as well as the template file location in the contributing plug-in.

  Returns:
    the unique section Id
  See Also:
    `getLabel()`, `getDescription()`, `getTemplateLocation()`

### getTemplateDirectory

    protected String getTemplateDirectory()

  Returns the directory where all the templates are located in the contributing plug-in.

  Returns:
    "templates_[schemaVersion]" for code since Eclipse 3.0, or "templates" for pre-3.0 code.

### getInstallURL

    protected abstract URL getInstallURL()

  Returns the install URL of the plug-in that contributes this template.

  Returns:
    the install URL of the contributing plug-in

### getTemplateLocation

    public URL getTemplateLocation()

  Implements the abstract method by looking for templates using the following path:

  [install location]/[templateDirectory]/[sectionId]

  Specified by:
    `getTemplateLocation` in interface `ITemplateSection`
  Overrides:
    `getTemplateLocation` in class `AbstractTemplateSection`
  Returns:
    the URL of the location where files to be emitted by this template are located.
  See Also:
    `ITemplateSection.getTemplateLocation()`

### getPage

    public WizardPage getPage(int pageIndex)

  Returns the wizard page at the specified index. Pages must be created prior to calling this method.

  Returns:
    the wizard page at the specified index or `null` if invalid index.
  See Also:
    `createPage(int)`

### createPage

    public WizardPage createPage(int pageIndex)

  Creates the wizard page for the specified page index. This method cannot be called before setPageCount(int). The page will be created with all the options registered for that page index. Therefore, make all the calls to addOption() before calling this method.

  Parameters:
    `pageIndex` - a zero-based index of the page relative to this template. For example, if a template need to have two pages, you have to call this method twice (once with index 0 and again with index 1).
  See Also:
    `setPageCount(int)`, `BaseOptionTemplateSection.addOption(java.lang.String, java.lang.String, boolean, int)`

### createPage

    public WizardPage createPage(int pageIndex,
                                 String helpContextId)

  Creates the wizard page for the specified page index. This method cannot be called before setPageCount(int). The page will be created with all the options registered for that page index. Therefore, make all the calls to addOption() before calling this method.

  Parameters:
    `pageIndex` - a zero-based index of the page relative to this template. For example, if a template need to have two pages, you have to call this method twice (once with index 0 and again with index 1).
    `helpContextId` - the Id of the help context defined in the contributing plug-in that will be used to locate content of the info-pop displayed when F1 is pressed.
  See Also:
    `setPageCount(int)`, `BaseOptionTemplateSection.addOption(java.lang.String, java.lang.String, boolean, int)`

### getPageCount

    public int getPageCount()

  Returns a number of pages that this template contributes to the wizard.

  Returns:
    the number of pages
  See Also:
    `setPageCount(int)`

### setPageCount

    public void setPageCount(int count)

  Sets the number of pages this template will manage. This method must be called prior to adding pages and options in order to initialize the template. Once the method has been called, you can call methods that accept page index in the range [0..count-1].

  Parameters:
    `count` - number of pages that this template will contribute to the template wizard

### getOptions

    public TemplateOption[] getOptions(int pageIndex)

  Returns options that belong to the page with the given index.

  Returns:
    the translated label of this template

### getDescription

    public String getDescription()

  Returns the description of this template to be used in the UI. The description is obtained by creating a lookup key using the following rule: "template.[section-id].desc". This key is used to locate the label in the plugin.properties file of the plug-in that contributed this template.
