## [Java] Class FactoryBuilderSupport

- groovy.util.FactoryBuilderSupport

- Mix of BuilderSupport and SwingBuilder's factory support. Warning: this implementation is not thread safe and should not be used across threads in a multi-threaded environment. A locking mechanism should be implemented by the subclass if use is expected across multiple threads.

    - #### protected void setNodeAttributes(Object node, Map attributes)

      Maps attributes key/values to properties on node.

      Parameters:
        `node` - the object from the node
        `attributes` - the attributes to be set

    - #### protected void setParent(Object parent, Object child)

      Strategy method to establish parent/child relationships.

      Parameters:
        `parent` - the object from the parent node
        `child` - the object from the child node

    - #### public void setProperty(String property, Object newValue)

      Overloaded to make variables appear as bean properties or via the subscript operator

    - #### public void setPropertyMissingDelegate(Closure delegate)

    - #### protected void setProxyBuilder(FactoryBuilderSupport proxyBuilder)

      Sets the builder to be used as a proxy.

      Parameters:
        `proxyBuilder` - the new proxy

    - #### public void setVariable(String name, Object value)

      Sets the value of the given variable

      Parameters:
        `name` - the name of the variable to set
        `value` - the new value for the given variable

    - #### public Object withBuilder(FactoryBuilderSupport builder, Closure closure)

      Switches the builder's proxyBuilder during the execution of a closure.
      This is useful to temporary change the building context to another builder without the need for a contrived setup. It will also take care of restoring the previous proxyBuilder when the execution finishes, even if an exception was thrown from inside the closure.

      throws:
        RuntimeException - any exception the closure might have thrown during execution.
      Parameters:
        `builder` - the temporary builder to switch to as proxyBuilder.
        `closure` - the closure to be executed under the temporary builder.
      Returns:
        the execution result of the closure.

    - #### public Object withBuilder(FactoryBuilderSupport builder, String name, Closure closure)

      Switches the builder's proxyBuilder during the execution of a closure.
      This is useful to temporary change the building context to another builder without the need for a contrived setup. It will also take care of restoring the previous proxyBuilder when the execution finishes, even if an exception was thrown from inside the closure. Additionally it will use the closure's result as the value for the node identified by 'name'.

      throws:
        RuntimeException - any exception the closure might have thrown during execution.
      Parameters:
        `builder` - the temporary builder to switch to as proxyBuilder.
        `name` - the node to build on the 'parent' builder.
        `closure` - the closure to be executed under the temporary builder.
      Returns:
        a node that responds to value of name with the closure's result as its value.

    - #### public Object withBuilder(Map attributes, FactoryBuilderSupport builder, String name, Closure closure)

      Switches the builder's proxyBuilder during the execution of a closure.
      This is useful to temporary change the building context to another builder without the need for a contrived setup. It will also take care of restoring the previous proxyBuilder when the execution finishes, even if an exception was thrown from inside the closure. Additionally it will use the closure's result as the value for the node identified by 'name' and assign any attributes that might have been set.

      throws:
        RuntimeException - any exception the closure might have thrown during execution.
      Parameters:
        `attributes` - additional properties for the node on the parent builder.
        `builder` - the temporary builder to switch to as proxyBuilder.
        `name` - the node to build on the 'parent' builder.
        `closure` - the closure to be executed under the temporary builder.
      Returns:
        a node that responds to value of name with the closure's result as its value.
