Constructor Details

HelloModelView

public HelloModelView(Function<Object,String> formatter,
 Function<String,String> escaper)

Renderer constructor for manual wiring.

Parameters:

formatter - formatter if null the static formatter will be used.

escaper - escaper if null the static escaper will be used

HelloModelView

public HelloModelView()

Renderer constructor for reflection (use of() instead). For programmatic consider using of() for a shared singleton.

HelloModelView

public HelloModelView(TemplateConfig templateConfig)

Renderer constructor using config.

Parameters:

templateConfig - config that has collaborators

Method Details

execute

public StringBuilder execute(HelloModel model,
 StringBuilder sb)

Description copied from interface: Renderer

A convenience method that does not throw IOException when using StringBuilder.

Specified by:

execute in interface Renderer<HelloModel>

Parameters:

model - a model assumed never to be null.

sb - should never be null.

Returns:

the passed in StringBuilder.

execute

public <A extends Output<E>,
E extends Exception> A execute(HelloModel model,
 A a)
                                                    throws E

Description copied from interface: Template

Renders the passed in model to an appendable like output.

Specified by:

execute in interface Renderer<HelloModel>

Specified by:

execute in interface Template<HelloModel>

Type Parameters:

A - output type

E - error type

Parameters:

model - a model assumed never to be null.

a - the appendable to write to.

Returns:

the output passed in returned for convenience.

Throws:

E - if there is an error writing to the output

execute

protected <A extends Output<E>,
E extends Exception>
void execute(HelloModel model,
 A a,
 Formatter formatter,
 Escaper escaper)
      throws E

Renders the passed in model.

Type Parameters:

A - appendable type.

E - error type.

Parameters:

model - a model assumed never to be null.

a - appendable to write to.

formatter - formats variables before they are passed to the escaper

escaper - used to write escaped variables

Throws:

E - if an error occurs while writing to the appendable

write

public <A extends Output.EncodedOutput<E>,
E extends Exception>
A write(HelloModel model,
 A outputStream)
 throws E

Description copied from interface: Template.EncodedTemplate

Renders the passed in model directly to a binary stream leveraging pre-encoded parts of the template. This may improve performance when rendering UTF-8 to an OutputStream as some of the encoding is done in advance. Because the encoding is done statically you cannot pass the charset in. The chosen charset comes from JStacheConfig.charset().

Specified by:

write in interface Template<HelloModel>

Specified by:

write in interface Template.EncodedTemplate<HelloModel>

Type Parameters:

A - output type

E - error type

Parameters:

model - a model assumed never to be null.

outputStream - to write to.

Returns:

the passed in output for convenience

Throws:

E - if an error occurs while writing to output

supportsType

public boolean supportsType(Class<?> type)

Description copied from interface: TemplateInfo

Checks to see if a template supports the model class.

Specified by:

supportsType in interface TemplateInfo

Parameters:

type - the class of the model.

Returns:

if this renderer supports the class.

templatePath

public String templatePath()

Description copied from interface: TemplateInfo

If the template is a classpath resource file this will return the location that was originally resolved via config resolution.

Specified by:

templatePath in interface TemplateInfo

Returns:

the location of the template or empty if the template is inlined.

See Also:

• TemplateInfo.normalizePath()

templateName

public String templateName()

Description copied from interface: TemplateInfo

The logical name of the template which maybe different than TemplateInfo.templatePath().

Specified by:

templateName in interface TemplateInfo

Returns:

logical name of template. Never null.

templateCharset

public Charset templateCharset()

Description copied from interface: TemplateInfo

The template Charset which is the original format of the template file and should ideally be used when encoding an HTTP response or similar. Furthermore ideally the template charset matches the chosen TemplateInfo.templateContentType() JStacheContentType.charsets() otherwise the escaper may not appropriately escape.

IF the template is inline or charset was not set this will usually be StandardCharsets.UTF_8.

Specified by:

templateCharset in interface TemplateInfo

Returns:

the template Charset.

See Also:

• JStacheContentType.charsets()
• JStacheConfig.charset()

templateMediaType

public String templateMediaType()

Description copied from interface: TemplateInfo

The template media-type from the JStacheContentType.

Specified by:

templateMediaType in interface TemplateInfo

Returns:

media type maybe an empty string.

templateString

public String templateString()

Description copied from interface: TemplateInfo

The raw contents of the template. Useful if the template is inline. To determine if the template is actually inline use TemplateInfo.templateSource().

Specified by:

templateString in interface TemplateInfo

Returns:

the raw contents of the template never null.

See Also:

• TemplateInfo.TemplateSource

templateContentType

public Class<?> templateContentType()

Description copied from interface: TemplateInfo

The template content type is the class annotated with JStacheContentType which also describes the escaper to be used.

Specified by:

templateContentType in interface TemplateInfo

Returns:

the template content type.

templateEscaper

public Escaper templateEscaper()

Description copied from interface: TemplateInfo

The escaper to be used on the template. See Escaper.of(Function).

Specified by:

templateEscaper in interface TemplateInfo

Returns:

the escaper.

See Also:

• Escaper

templateFormatter

public Formatter templateFormatter()

Description copied from interface: TemplateInfo

The base formatter to be used on the template. See Formatter.of(Function).

Specified by:

templateFormatter in interface TemplateInfo

Returns:

the formatter.

See Also:

• Formatter

templateAppender

public Appender templateAppender()

Appender.

Returns:

appender for writing unescaped variables.
