- Method Detail
  - builder
```
public IFileListBuilder builder()
```
    Description copied from interface: IFileListDescriptor
    
    Creates a new builder for configuring a file list conforming to this descriptor.
    
    Specified by:
    
    builder in interface IFileListDescriptor
    
    Returns:
    
    A new builder for configuring a file list conforming to this descriptor.
  - getAttributes
```
public Map<String,Object> getAttributes()
```
    Description copied from interface: IFileListDescriptor
    
    Gets a map of additional custom attributes associated with this file list. The exact meaning of these attributes is up to the user of the file value descriptor API.
    See StandardValueDescriptorAttributes for some standard attribute keys.
    
    Specified by:
    
    getAttributes in interface IAttributeConfigurable<IFileListDescriptor>
    
    Specified by:
    
    getAttributes in interface IFileListDescriptor
    
    Returns:
    
    A map of additional attributes associated with the file list.
    
    See Also:
    
    StandardValueDescriptorAttributes
  - getContentTypes
```
public Set<String> getContentTypes()
```
    Description copied from interface: IFileListDescriptor
    
    The content types of the files that might be contained in the list of files. Each content type is a MIME type. Use "*/*" when the content type is unknown or any type of file might be contained in the list. Use an asterisk as a wildcard to allow a range of content types, e.g. "image/*". An empty set allows no files.
    null is treated as if the empty set had been returned.
    
    Specified by:
    
    getContentTypes in interface IFileListDescriptor
    
    Returns:
    
    The content types of the files that might be contained in the list of files.
  - getExtensions
```
public Set<String> getExtensions()
```
    Description copied from interface: IFileListDescriptor
    
    The file extensions of the files that can be contained in the list of files. Each extension is a string without a leading dot, e.g. "pdf" or "png". Use the empty string "" to allow files without an extension. Use a set with a single entry "*" when the extension is unknown or any extension is allowed. An empty set allows no files.
    Implementations should normalize extensions to lower case, so that this method always returns lower case extensions.
    null is treated as if the empty set had been returned.
    
    Specified by:
    
    getExtensions in interface IFileListDescriptor
    
    Returns:
    
    The file extensions of the files that can be contained in the list of files.
  - getMaxFileCount
```
public int getMaxFileCount()
```
    Description copied from interface: IFileListDescriptor
    
    The maximum number of files that will be contained in the list of files. MAX_VALUE when there is no limit.
    
    Specified by:
    
    getMaxFileCount in interface IFileListDescriptor
    
    Returns:
    
    The maximum number of files that will be contained in the list of files.
  - getMinFileCount
```
public int getMinFileCount()
```
    Description copied from interface: IFileListDescriptor
    
    The minimum number of files that are contained in the list of files. 0 when the list might be empty, 1 if the list will contain at least one file.
    
    Specified by:
    
    getMinFileCount in interface IFileListDescriptor
    
    Returns:
    
    The minimum number of files that are contained in the list of files.
  - intersect
```
public IFileListDescriptor intersect(IFileListDescriptor other)
```
    Description copied from interface: IFileListDescriptor
    
    Intersects this file list descriptor with another file list descriptor. The intersection of two file list descriptors is a new file list descriptor that only allows files that are allowed by both file list descriptors. When the two file list descriptors are incompatible, returns an empty descriptor.
    This operation is, for the most part, symmetric / commutative. The only exception is the attribute map of the files. When both input descriptors have an attribute with the same key but different values, the value from the right hand side is used.
    
    Specified by:
    
    intersect in interface IFileListDescriptor
    
    Parameters:
    
    other - The other file list descriptor to intersect with.
    
    Returns:
    
    The intersection of this file list descriptor with the other file list descriptor.
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object

public IFileListDescriptor withAddedAttribute(String key,
                                              Object value)
```
    Description copied from interface: IAttributeConfigurable
    
    Gets a new instance with the attribute at the given key changed to the given value.
    
    Specified by:
    
    withAddedAttribute in interface IAttributeConfigurable<IFileListDescriptor>

    key - The attribute key.
    
    value - The attribute value.
    
    Returns:
    
    A new instance with the new attribute.
  - withAddedAttributes
```
public IFileListDescriptor withAddedAttributes(Map<String,Object> newAttributes)
```
    Description copied from interface: IAttributeConfigurable
    
    Gets a new instance with the attributes changed to the given map of attributes. Preserves other existing attributes and only adds or replaces the given ones.

  - empty
```
public static IFileListDescriptor empty()
```
    Returns an empty IFileListDescriptor that does not allow any files.
    
    Returns:
    
    An empty descriptor that does not allow any files.
