Constructor Details

MappedResourceCollection

public MappedResourceCollection()

Method Details

add

public void add(ResourceCollection c)
         throws BuildException

Adds the required nested ResourceCollection.

Parameters:

c - the ResourceCollection to add.

Throws:

BuildException - on error.

createMapper

public Mapper createMapper()
                    throws BuildException

Define the mapper to map source to destination files.

Returns:

a mapper to be configured.

Throws:

BuildException - if more than one mapper is defined.

add

public void add(FileNameMapper fileNameMapper)

Add a nested filenamemapper.

Parameters:

fileNameMapper - the mapper to add.

Since:

Ant 1.6.3

setEnableMultipleMappings

public void setEnableMultipleMappings(boolean enableMultipleMappings)

Set method of handling mappers that return multiple mappings for a given source path.

Parameters:

enableMultipleMappings - If true the type will use all the mappings for a given source path, if false, only the first mapped name is processed. By default, this setting is false to provide backward compatibility with earlier releases.

Since:

Ant 1.8.1

setCache

public void setCache(boolean cache)

Set whether to cache collections.

Parameters:

cache - boolean

Since:

Ant 1.8.1

isFilesystemOnly

public boolean isFilesystemOnly()

Indicate whether this ResourceCollection is composed entirely of Resources accessible via local filesystem conventions. If true, all resources returned from this collection should respond with a FileProvider when asked via Resource.as(Class).

Specified by:

isFilesystemOnly in interface ResourceCollection

Returns:

whether this is a filesystem-only resource collection.

size

public int size()

Learn the number of contained Resources.

Specified by:

size in interface ResourceCollection

Returns:

number of elements as int.

iterator

public Iterator<Resource> iterator()

Specified by:

iterator in interface Iterable<Resource>

setRefid

public void setRefid(Reference r)

Overrides the base version.

Overrides:

setRefid in class DataType

Parameters:

r - the Reference to set.

clone

public Object clone()

Implement clone. The nested resource collection and mapper are copied.

Overrides:

clone in class DataType

Returns:

a cloned instance.

dieOnCircularReference

protected void dieOnCircularReference(Stack<Object> stk,
 Project p)
                               throws BuildException

Overrides the version of DataType to recurse on all DataType child elements that may have been added.

Overrides:

dieOnCircularReference in 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.

toString

public String toString()

Format this resource collection as a String.

Overrides:

toString in class DataType

Returns:

a descriptive String.
