Direct Known Subclasses:

ERXDirectActionImage

public class ERXDirectActionHyperlink
extends ERXStatelessComponent

This component can be used for two things:

1. Generating direct action urls for use in components that are being e-mailed to people.
2. Support for encoding enterprise objects in the form values of generated urls. At the moment this component still contains some custy code that needs to be cleaned up before it can really be used, like adding the .wo and .api files ;0.

Synopsis:

Constructor Detail

ERXDirectActionHyperlink

public ERXDirectActionHyperlink(com.webobjects.appserver.WOContext aContext)

Public constructor

Parameters:

aContext - a context

Method Detail

entityNameSeparator

public String entityNameSeparator()

Cover method to return the binding: entityNameSeparator The entity name separator is used when constructing URLs with enterprise objects encoded in the url. This value default to the value defined in the system property er.extensions.ERXDirectActionHyperlink.EntityNameSeparator which defaults as well to the character '

_

'.

Returns:

returns the value for binding: entityNameSeparator

relative

public boolean relative()

Cover method to return the boolean value of the binding: relative Defaults to true.

Returns:

returns if the generated url should be relative or not(absolute).

shouldEncryptObjectFormValues

public boolean shouldEncryptObjectFormValues()

Cover method to return the boolean value of the binding: shouldEncryptObjectFormValues Defaults to false.

Returns:

returns if the encoded objects' primary keys should be encrypted or not.

objectsForFormValues

public NSArray objectsForFormValues()

Cover method to return the binding: objectsForFormValues This is an array of objects to be encoded as form values.

Returns:

returns bound array of objects to be encoded

objectForFormValue

public com.webobjects.eocontrol.EOEnterpriseObject objectForFormValue()

Cover method to return the binding: objectsForFormValue This is an enterprise object to be encoded as form values.

Returns:

returns bound enterprise object to be encoded

allObjectsForFormValues

public NSArray allObjectsForFormValues()

Returns all of the objects to be encoded in the form values. Collects those bound to both 'objectsForFormValues' and 'objectForFormValue' into a single array.

Returns:

complete collection of objects to be encoded in form values.

href

public String href()

Generates an href for the given direct action based on all of the bindings. Currently it generates an absolute url starting with the key: ADAPTOR_PREFIX_MARKER. Before this href can be really useful it needs to be cleaned up.

Returns:

href containing all of the specification from the bindings.

applicationHostUrl

public static String applicationHostUrl()

This returns the value stored in the system properties: ERApplicationHostURL if this isn't set then a runtime exception is thrown. This property should be of the form: http://mymachine.com

Returns:

the application host url that should be used when complete urls are generated.

directActionHyperlink

public static String directActionHyperlink(com.webobjects.appserver.WOContext context,
                                           boolean encryptEos,
                                           NSArray eos,
                                           String entityNameSeparator,
                                           NSDictionary encryptedDict,
                                           NSDictionary unencryptedDict,
                                           String appName,
                                           String daName,
                                           boolean relative,
                                           String suffix)

completeURLFromString

public static String completeURLFromString(String s,
                                           com.webobjects.appserver.WOContext c,
                                           String applicationName,
                                           boolean relative,
                                           String suffix)

This method is useful for completing urls that are being generated in components that are going to be e-mailed to users. This method has the ability to substitute different application names which can be helpful if one application is generating the component, but the action of the url points to a different application on the same host.

Parameters:

s - href string to be completed

c - current context

applicationName - to be substituted if ADAPTOR_PREFIX_MARKER is present

relative - flag to indicate if the generated url should be relative or absolute in which case the applicationHostUrl will be used

suffix - string to be substitued if the SUFFIX_MARKER string is present

Returns:

complete url after substitutions have been made
