DynamicContent

• java.lang.Object
  • Content

Fields Summary
private static final int	MAX_INSTANCES maximum number of instances of content to keep for each template
protected static final String	ALL_PERMISSIONS_JNLP_SETTING JNLP element to request full permissions - used if the app client jar is signed
protected static final String	NO_PERMISSIONS_JNLP_SETTING JNLP element to request no permissions - used if the app client jar is not signed - no perms is the JNLP default
private String	template the template which will be used at runtime to create the actual response to the HTTP request
protected String	mimeType the MIME type of the data represented by this DynamicContent instance
private LinkedList	instances content instances resulting from previous HTTP GET requests
private boolean	requiresElevatedPermissions records whether this content should request elevated permissions

Constructors Summary
public DynamicContent(ContentOrigin origin, String contentKey, String path, String template, String mimeType) Returns a new instance of DynamicContent. param origin the ContentOrigin for the new content instance param contentKey the content key used to store and retrieve the content param path the path relative to the subcategory in which this document is addressable param mimeType the MIME type of data represented by the content generated by this object. return new DynamicContent object this(origin, contentKey, path, template, mimeType, false /* requiresElevatedPermissions */);
public DynamicContent(ContentOrigin origin, String contentKey, String path, String template, String mimeType, boolean requiresElevatedPermissions) Returns a new instance of DynamicContent. param origin the ContentOrigin for the new content instance param contentKey the content key used to store and retrieve the content param path the path relative to the subcategory in which this document is addressable param mimeType the MIME type of data represented by the content generated by this object. return new DynamicContent object super(origin, contentKey, path); this.template = template; this.mimeType = mimeType; this.requiresElevatedPermissions = requiresElevatedPermissions;

Methods Summary
private void	addInstance(com.sun.enterprise.appclient.jws.DynamicContent$Instance newInstance) Adds a new content instance to this dynamic content. If adding the instance makes the cache too long, discards the oldest instance. param newInstance the new instance to be added to the cache synchronized (instances) { instances.addFirst(newInstance); if (instances.size() > MAX_INSTANCES) { instances.removeLast(); } }
protected void	clearInstances() Clears the cached instances. instances.clear();
public com.sun.enterprise.appclient.jws.DynamicContent$Instance	findInstance(java.util.Properties tokenValues, boolean createIfAbsent) Returns the DynamicContent.Instance for this template corresponding to the specified substitution token values. param tokenValues the name/value pairs to be substituted in the template param createIfAbsent selects whether a new DynamicContent.Instance should be created for the resulting text if the content text resulting from the substitution is not already cached by this DynamicContent. return the instance corresponding to the content generated by the tokenValues; null if no such instance already exists for this DynamicContent and createIfAbsent was false. Instance result = null; String textWithPlaceholdersReplaced = Util.replaceTokens(template, tokenValues); /* *Look for an instance with its text matching the just-computed replacement text. */ synchronized (instances) { for (Instance i : instances) { if (i.textEquals(textWithPlaceholdersReplaced)) { result = i; break; } } if (result == null && createIfAbsent) { result = new Instance(textWithPlaceholdersReplaced); addInstance(result); } } return result;
public java.lang.String	getJNLPSecuritySetting() Returns the appropriate JNLP security setting for this content, based on whether it requires elevated permissions or not. return the JNLP element string or an empty string if no privs are needed return requiresElevatedPermissions ? ALL_PERMISSIONS_JNLP_SETTING : NO_PERMISSIONS_JNLP_SETTING;
public java.lang.String	getMimeType() Returns the MIME type associated with this content. return the MIME type for this content return mimeType;
public boolean	requiresElevatedPermissions() Returns whether this dynamic content requires elevated permissions. return true if the related static content does require elevated permissions return requiresElevatedPermissions;
public java.lang.String	toString() Returns a string representation of the DynamicContent. return super.toString() + ", template=" + template + ", MIME type=" + mimeType;// + ", most recent change in generated content=" + timestamp;
