How to Retrieve a List of Attributes Defined for a Specific StringTemplate?

How can I obtain a list of attributes defined for a specific StringTemplate in my application?

StringTemplate, a powerful template engine, allows developers to define templates with specific attributes. Retrieving these attributes is essential for understanding and utilizing templates effectively.

StringTemplate template = new StringTemplate("Hello, $name$!");
template.setAttribute("name", "John");
List<String> attributes = template.getAttributes();
System.out.println(attributes); // Output: [name]

Causes

• Incorrect template instance retrieval.
• Misconfiguration in the StringTemplate setup.
• Using outdated or incompatible library versions.

Solutions

• Use the getAttributes() method from the StringTemplate instance to retrieve attribute names.
• Ensure that the template is correctly initialized before attempting to access its attributes.
• Check if you are using the latest version of StringTemplate for compatibility.

Mistake: Attempting to retrieve attributes from a non-initialized template.

Solution: Always ensure your StringTemplate instance is initialized and attributes are set before retrieval.

Mistake: Using a method not suited for StringTemplate to fetch attributes.

Solution: Utilize the correct StringTemplate methods like getAttributes() to obtain attribute lists.
