Class Template

java.lang.Object

com.samskivert.mustache.Template

public class Template
extends Object

Represents a compiled template. Templates are executed with a context to generate output. The context can be any tree of objects. Variables are resolved against the context. Given a name foo, the following mechanisms are supported for resolving its value (and are sought in this order):

• If the variable has the special name this the context object itself will be returned. This is useful when iterating over lists.
• If the object is a Map, Map.get(java.lang.Object) will be called with the string foo as the key.
• A method named foo in the supplied object (with non-void return value).
• A method named getFoo in the supplied object (with non-void return value).
• A field named foo in the supplied object.

The field type, method return type, or map value type should correspond to the desired behavior if the resolved name corresponds to a section. Boolean is used for showing or hiding sections without binding a sub-context. Arrays, Iterator and Iterable implementations are used for sections that repeat, with the context bound to the elements of the array, iterator or iterable. Lambdas are current unsupported, though they would be easy enough to add if desire exists. See the Mustache documentation for more details on section behavior.

Field Detail

NO_FETCHER_FOUND

public static final Object NO_FETCHER_FOUND

A sentinel object that can be returned by a Mustache.Collector to indicate that a variable does not exist in a particular context.

Method Detail

execute

public String execute(Object context)
               throws MustacheException

Executes this template with the given context, returning the results as a string.

Throws:

MustacheException - if an error occurs while executing or writing the template.

execute

public void execute(Object context,
                    Writer out)
             throws MustacheException

Executes this template with the given context, writing the results to the supplied writer.

Throws:

MustacheException - if an error occurs while executing or writing the template.

execute

public void execute(Object context,
                    Object parentContext,
                    Writer out)
             throws MustacheException

Executes this template with the supplied context and parent context, writing the results to the supplied writer. The parent context will be searched for variables that cannot be found in the main context, in the same way the main context becomes a parent context when entering a block.

Throws:

MustacheException - if an error occurs while executing or writing the template.
