Class VelocityMethods

java.lang.Object

io.toro.martini.VelocityMethods

public final class VelocityMethods
extends Object

A utility class for Velocity-related operations.

Apache Velocity is a Java-based template engine that provides a template language to reference objects defined in Java code. The one-liners in this class make it easy to parse Velocity templates.

Method Detail

parse

public static String parse(@GloopParameter(allowNull=false)
                           String template,
                           @GloopParameter(allowNull=false)
                           Map<String,Object> params)

Parses a Velocity template.

Example usage:

 def context = [ "firstname": "James", "lastname": "Greg" ]
 def template = 'Hello, $firstname $lastname.'
 def parsedTemplate = template.parse( context );
 assert parsedTemplate.equals( 'Hello, James Greg.' )
 

A variable called esb is added to the context as well, which can be used to call one-liners from GroovyMethods.

Parameters:

template - the template to parse

params - the context, which contains values which will be mapped to variables used in the template

Returns:

evaluated Velocity template

Since:

1.0

parse

public static String parse(String template)

Parses a Velocity template.

Example usage:

 def template = 'Hello, world.'
 def parsedTemplate = template.parse();
 assert parsedTemplate.equals( 'Hello, world.' )
 

Parameters:

template - the template to parse

Returns:

evaluated Velocity template

Since:

1.0

parse

public static String parse(Map params,
                           groovy.lang.Closure<Object> template)

Parses a Velocity template.

Example usage:

 def context = [ "firstname": "James", "lastname": "Greg" ]
 def template = { 'Hello, $firstname $lastname.' }
 def parsedTemplate = context.parse( template );
 assert parsedTemplate.equals( 'Hello, James Greg.' )
 

A variable called esb is added to the context as well, which can be used to call one-liners from GroovyMethods.

Parameters:

params - the context, which contains values which will be mapped to variables used in the template

template - a closure returning the template to parse

Returns:

evaluated Velocity template

Since:

1.0

parse

public static String parse(String template,
                           groovy.lang.Closure<Map> params)

Parses a Velocity template.

Example usage:

 def context = [ "firstname": "James", "lastname": "Greg" ]
 def template = 'Hello, $firstname $lastname.'
 def parsedTemplate = context.parse( template );
 assert parsedTemplate.equals( 'Hello, James Greg.' )
 

A variable called esb is added to the context as well, which can be used to call one-liners from GroovyMethods.

Parameters:

template - the template to parse

params - the context, which contains values which will be mapped to variables used in the template

Returns:

evaluated Velocity template

Since:

1.0

parse

public static String parse(@GloopParameter(allowNull=false)
                           String template,
                           GloopExecutionContext context)

Parses a Velocity template, using all the variables available in the current Gloop context.

Parameters:

template - the template to parse

context - the Gloop execution context (automatically mapped by Gloop), from which the template context will be derived; the context contains values which will be mapped to variables used in the template

Returns:

evaluated Velocity template

Since:

1.0

parse

public static String parse(@GloopParameter(allowNull=false)
                           String template,
                           GloopModel context,
                           GloopExecutionContext gloopExecutionContext)

Parses a Velocity template, using all the variables available in the current Gloop context, and provided context.

Parameters:

template - the template to parse

context - the context, which contains values which will be mapped to variables used in the template

gloopExecutionContext - the Gloop execution context (automatically mapped by Gloop), from which the template context will be derived; the context contains values which will be mapped to variables used in the template

Returns:

evaluated Velocity template

Since:
