Class CompositeFileFilter

java.lang.Object

com.adaptris.core.fs.CompositeFileFilter

All Implemented Interfaces:

java.io.FileFilter

public class CompositeFileFilter
extends java.lang.Object
implements java.io.FileFilter

A FileFilter that contains other filters.

It is designed for use with either the FsConsumer or FtpConsumer, this filter creates its underlying filters from a single __@@__ separated string (this notation was chosen so that it is unlikely to be used as a pattern matching sequence).

The format of the string required is 'FILTER_TYPE'='filter-expression' where the following types of filter are understood (case matters).

• NewerThan is equivalent to using NewerThan
• OlderThan is equivalent to using OlderThan
• SizeGT is equivalent to using SizeGreaterThan SizeGreaterThan
• SizeGTE is equivalent to using SizeGreaterThanOrEqual
• SizeLT is equivalent to using SizeLessThan
• SizeLTE is equivalent to using SizeLessThanOrEqual
• Regex is equivalent to using org.apache.commons.io.filefilter.RegexFileFilter - since 3.7.0

In the event of a unknown filter type being used, it will be assumed to be a fully qualified classname which will be constructed using reflection; the filter-expression will be passed in as the sole constructor argument.

The filter-expression value is something that is understood by the filter in question. e.g. the size in bytes for Size based filters, any errors encountered attempting to create filter results in the filter being ignored.

The filter only accepts the file if all the underlying filters accept the file, thus this represents an implicit AND condition. So for example we would use SizeGT=4096__@@__Perl=.*\.xml to match all files ending with .xml whose size is greater than 4096 bytes
