Example 1 with JsCodeBuilder

use of com.google.template.soy.jssrc.internal.JsCodeBuilder in project closure-templates by google.

the class GenIncrementalDomCodeVisitor method visitPrintNode.

/**
 * Visit an {@link PrintNode}, with special cases for a variable being printed within an attribute
 * declaration or as HTML content.
 *
 * <p>For attributes, if the variable is of kind attributes, it is invoked. Any other kind of
 * variable is an error.
 *
 * <p>For HTML, if the variable is of kind HTML, it is invoked. Any other kind of variable gets
 * wrapped in a call to {@code incrementalDom.text}, resulting in a Text node.

Example 2 with JsCodeBuilder

use of com.google.template.soy.jssrc.internal.JsCodeBuilder in project closure-templates by google.

the class GenIncrementalDomCodeVisitor method visitRawTextNode.

/**
 * Visits a {@link RawTextNode}, which occurs either as a child of any BlockNode or the 'child' of
 * an HTML tag. Note that in the soy tree, tags and their logical HTML children do not have a
 * parent-child relationship, but are rather siblings. For example:
 *
 * <pre>
 * &lt;div&gt;Hello world&lt;/div&gt;
 * </pre>
 *
 * The text "Hello world" translates to
 *
 * <pre>
 * incrementalDom.text('Hello world');
 * </pre>
