Agora daremos sequencia no tutorial, lembrando que no passo 1 criamos a classe MyFormatFeatureResponseDelegate.java.<\/p>\n

PASSO 2:<\/strong> Criando a classe MyFormatFeatureResponseDelegateFactory.java<\/p>\n

No pacote org.vfny.geoserver.wfs.responses, crie sua classe MyFormatFeatureResponseDelegateProducer.java, ela deve implementar a interface FeatureResponseDelegateProducerSpi:<\/p>\n

[source language=”:Java”]
\npublic interface FeatureResponseDelegateProducerSpi
\n extends Factory
\n{
\n String getName();<\/p>\n

Set getSupportedFormats();<\/p>\n

boolean isAvailable();<\/p>\n

boolean canProduce(String format);<\/p>\n

FeatureResponseDelegate
\n createFeatureDelegateProducer(String format)
\n throws IllegalArgumentException;
\n[\/source]<\/p>\n

Crie tamb\u00e9m um atributo est\u00e1tico do tipo java.util.HashSet. Nele, armazene os tipos poss\u00edveis que esta factory permite. Esta aqui um exemplo do GML2FeatureResponseDelegateFactory:<\/p>\n

[source language=”:Java”]
\nstatic HashSet supportedFormats = new HashSet();<\/p>\n

static{
\n supportedFormats.add("GML2");
\n supportedFormats.add("GML2-GZIP");
\n}
\n[\/source]<\/p>\n

O m\u00e9todo getName(), retorna o nome da inst\u00e2ncia da factory. No ShapefileFeatureResponseDelegateFactory \u00e9 assim por exemplo:<\/p>\n

[source language=”:Java”]
\npublic String getName() {
\n return "Shapefile Output
\n (compressed in a zip file)";
\n}
\n[\/source]<\/p>\n

O m\u00e9todo getSupportedFormats(), retorna todos os tipos de sa\u00eddas suportados. Basta fazer conforme o c\u00f3digo abaixo:<\/p>\n

[source language=”:Java”]
\npublic Set getSupportedFormats()
\n{
\n return supportedFormats;
\n}
\n[\/source]<\/p>\n

O m\u00e9todo isAvailable() determina quando o factory pode criar novas inst\u00e2ncias. Nas classes ShapefileFeatureResponseDelegateFactory e GML2FeatureResponseDelegateFactory o retorno \u00e9 simplesmente verdadeiro(true<\/strong>).<\/p>\n

J\u00e1 o m\u00e9todo canProduce(String format), retorna true se o factory pode criar o formato de sa\u00edda especificado. Ele tem a mesma fun\u00e7\u00e3o do canProduce() da classe MyFormatFeatureResponseDelegate.<\/p>\n

Este m\u00e9todo criar\u00e1 um nvo MyFormatFeatureResponseDelegate. Deve verificar para ver se o formato puder ser criado, e ent\u00e3o criar\u00e1 o objeto. \u00c9 aqui o que o m\u00e9todo GML2FeatureResponseDelegateFactory:<\/p>\n

[source language=”:Java”]
\npublic FeatureResponseDelegate
\n createFeatureDelegateProducer(String format)
\n throws IllegalArgumentException
\n{
\n\tif (canProduce(format))
\n return new GML2FeatureResponseDelegate();
\n\tthrow new IllegalArgumentException("cannot
\n produce "+format);
\n}
\n[\/source]<\/p>\n
