brooklyn.entity.proxy.nginx
[Java] Class UrlMappingImpl

java.lang.Object
  brooklyn.entity.basic.AbstractEntity
      brooklyn.entity.basic.AbstractGroupImpl
          brooklyn.entity.proxy.nginx.UrlMappingImpl
All Implemented Interfaces:
UrlMapping
public class UrlMappingImpl
extends AbstractGroupImpl

This is a group whose members will be made available to a load-balancer / URL forwarding service (such as nginx). Configuration requires a domain and some mechanism for finding members. The easiest way to find members is using a target whose children will be tracked, but alternative membership policies can also be used.

Method Detail

addRewrite

@Override
public UrlMapping addRewrite(java.lang.String from, java.lang.String to)
adds a rewrite rule, must be called at config time. see UrlRewriteRule for more info.

addRewrite

@Override
public UrlMapping addRewrite(UrlRewriteRule rule)
adds a rewrite rule, must be called at config time. see UrlRewriteRule for more info.

discard

return false;
public void discard()

getAddressOfEntity

protected java.lang.String getAddressOfEntity(Entity s)
defines how address string, ie hostname:port, is constructed from a given entity. returns null if not possible.

the default is to look at HOSTNAME and HTTPS_PORT or HTTP_PORT attribute sensors (depending on SSL_CONFIG being set with targetIsSsl).

this method is suitable (intended) for overriding if needed.

getDomain

@Override
public java.lang.String getDomain()

getPath

@Override
public java.lang.String getPath()

getSubscriptionHandle

protected SubscriptionHandle getSubscriptionHandle()

getTarget

@Override
public Entity getTarget()

getUniqueLabel

@Override
public java.lang.String getUniqueLabel()

onManagementStarting

@Override
public void onManagementStarting()

recompute

boolean changed = (event.getValue()) ? addMember(event.getSource()) : removeMember(event.getSource());
public void recompute()

recomputeAddresses

protected void recomputeAddresses()

setTarget

@Override
public void setTarget(Entity target)
