Example 6 with ClassData

use of com.google.template.soy.jbcsrc.internal.ClassData in project closure-templates by google.

the class TemplateCompiler method compile.

/**
 * Returns the list of classes needed to implement this template.
 *
 * <p>For each template, we generate:
 *
 * <ul>
 *   <li>A {@link com.google.template.soy.jbcsrc.shared.CompiledTemplate.Factory}
 *   <li>A {@link CompiledTemplate}
 *   <li>A DetachableSoyValueProvider subclass for each {@link LetValueNode} and {@link
 *       CallParamValueNode}
 *   <li>A DetachableContentProvider subclass for each {@link LetContentNode} and {@link
 *       CallParamContentNode}
 *       <p>Note: This will <em>not</em> generate classes for other templates, only the template
 *       configured in the constructor. But it will generate classes that <em>reference</em> the
 *       classes that are generated for other templates. It is the callers responsibility to
 *       ensure that all referenced templates are generated and available in the classloader that
 *       ultimately loads the returned classes.
