Method Details- 
setCachepublic void setCache(boolean b) Set whether to cache collections.- Parameters:
- b- boolean cache flag.
 
- 
isCachepublic boolean isCache()Learn whether to cache collections. Default istrue.- Returns:
- boolean cache flag.
 
- 
addAdd a ResourceCollection to the container.- Parameters:
- c- the ResourceCollection to add.
- Throws:
- BuildException- on error.
 
- 
iterator
- 
createIteratorDo create an iterator on the resource collection. The creation of the iterator is allowed to not be thread safe whereas the iterator itself should. The returned iterator will be wrapped into the FailFast one.- Returns:
- the iterator on the resource collection
 
- 
sizepublic int size()Fulfill the ResourceCollection contract.- Specified by:
- sizein interface- ResourceCollection
- Returns:
- number of elements as int.
 
- 
getSizeprotected abstract int getSize()Do compute the size of the resource collection. The implementation of this function is allowed to be not thread safe.- Returns:
- size of resource collection.
 
- 
isFilesystemOnlypublic boolean isFilesystemOnly()Fulfill the ResourceCollection contract.- Specified by:
- isFilesystemOnlyin interface- ResourceCollection
- Returns:
- whether this is a filesystem-only resource collection.
 
- 
dieOnCircularReferenceOverrides the version of DataType to recurse on all DataType child elements that may have been added.- Overrides:
- dieOnCircularReferencein class- DataType
- Parameters:
- stk- the stack of data types to use (recursively).
- p- the project to use to dereference the references.
- Throws:
- BuildException- on error.
 
- 
getResourceCollectionGet the nested ResourceCollection.- Returns:
- a ResourceCollection.
- Throws:
- BuildException- if no nested ResourceCollection has been provided.
