Methods Summary
public int	getAvailableExtensionCount() Gets the number of available extensions return The number of available extensions return (availableExtensions != null) ? availableExtensions.size() : 0;
private java.util.ArrayList	getAvailableExtensions(java.util.jar.Manifest manifest) Return the set of Extension objects representing optional packages that are bundled with the application associated with the specified Manifest. param manifest Manifest to be parsed return List of available extensions, or null if the web application does not bundle any extensions Attributes attributes = manifest.getMainAttributes(); String name = attributes.getValue("Extension-Name"); if (name == null) return null; ArrayList extensionList = new ArrayList(); Extension extension = new Extension(); extension.setExtensionName(name); extension.setImplementationURL( attributes.getValue("Implementation-URL")); extension.setImplementationVendor( attributes.getValue("Implementation-Vendor")); extension.setImplementationVendorId( attributes.getValue("Implementation-Vendor-Id")); extension.setImplementationVersion( attributes.getValue("Implementation-Version")); extension.setSpecificationVersion( attributes.getValue("Specification-Version")); extensionList.add(extension); return extensionList;
public java.util.ArrayList	getAvailableExtensions() Gets the list of available extensions return List of available extensions return availableExtensions;
public int	getRequiredExtensionCount() Gets the number of required extensions return The number of required extensions return (requiredExtensions != null) ? requiredExtensions.size() : 0;
private java.util.ArrayList	getRequiredExtensions(java.util.jar.Manifest manifest) Return the set of Extension objects representing optional packages that are required by the application associated with the specified Manifest. param manifest Manifest to be parsed return List of required extensions, or null if the application does not require any extensions Attributes attributes = manifest.getMainAttributes(); String names = attributes.getValue("Extension-List"); if (names == null) return null; ArrayList extensionList = new ArrayList(); names += " "; while (true) { int space = names.indexOf(' "); if (space < 0) break; String name = names.substring(0, space).trim(); names = names.substring(space + 1); String value = attributes.getValue(name + "-Extension-Name"); if (value == null) continue; Extension extension = new Extension(); extension.setExtensionName(value); extension.setImplementationURL (attributes.getValue(name + "-Implementation-URL")); extension.setImplementationVendorId (attributes.getValue(name + "-Implementation-Vendor-Id")); String version = attributes.getValue(name + "-Implementation-Version"); extension.setImplementationVersion(version); extension.setSpecificationVersion (attributes.getValue(name + "-Specification-Version")); extensionList.add(extension); } return extensionList;
public java.util.ArrayList	getRequiredExtensions() Gets the list of required extensions return List of required extensions return requiredExtensions;
public java.lang.String	getResourceName() Gets the name of the resource return The name of the resource return resourceName;
