Method Detail

filterTypeInOutputs

public static <T> Iterator<T> filterTypeInOutputs(List<ProcessorDefinition> outputs,
                                                  Class<T> type)

Looks for the given type in the list of outputs and recurring all the children as well.

Parameters:

outputs - list of outputs, can be null or empty.

type - the type to look for

Returns:

the found definitions, or null if not found

findFirstTypeInOutputs

public static <T> T findFirstTypeInOutputs(List<ProcessorDefinition> outputs,
                                           Class<T> type)

Looks for the given type in the list of outputs and recurring all the children as well. Will stop at first found and return it.

Parameters:

outputs - list of outputs, can be null or empty.

type - the type to look for

Returns:

the first found type, or null if not found

isFirstChildOfType

public static boolean isFirstChildOfType(Class<?> parentType,
                                         ProcessorDefinition<?> node)

Is the given child the first in the outputs from the parent?

Parameters:

parentType - the type the parent must be

node - the node

Returns:

true if first child, false otherwise

isParentOfType

public static boolean isParentOfType(Class<?> parentType,
                                     ProcessorDefinition<?> node,
                                     boolean recursive)

Is the given node parent(s) of the given type

Parameters:

parentType - the parent type

node - the current node

recursive - whether or not to check grand parent(s) as well

Returns:

true if parent(s) is of given type, false otherwise

getRoute

public static RouteDefinition getRoute(ProcessorDefinition<?> node)

Gets the route definition the given node belongs to.

Parameters:

node - the node

Returns:

the route, or null if not possible to find

hasOutputs

public static boolean hasOutputs(List<ProcessorDefinition> outputs,
                                 boolean excludeAbstract)

Is there any outputs in the given list.

Is used for check if the route output has any real outputs (non abstracts)

Parameters:

outputs - the outputs

excludeAbstract - whether or not to exclude abstract outputs (e.g. skip onException etc.)

Returns:

true if has outputs, otherwise false is returned
