类 SuffixFileFilter

java.lang.Object

org.apache.commons.io.filefilter.AbstractFileFilter

org.apache.commons.io.filefilter.SuffixFileFilter

所有已实现的接口:

FileFilter, FilenameFilter, Serializable, IOFileFilter

public class SuffixFileFilter
extends AbstractFileFilter
implements Serializable

Filters files based on the suffix (what the filename ends with). This is used in retrieving all the files of a particular type.

For example, to retrieve and print all *.java files in the current directory:

 File dir = new File(".");
 String[] files = dir.list( new SuffixFileFilter(".java") );
 for (int i = 0; i < files.length; i++) {
     System.out.println(files[i]);
 }
 

从以下版本开始:

1.0

SuffixFileFilter

public SuffixFileFilter(String suffix)

Constructs a new Suffix file filter for a single extension.

参数:

suffix - the suffix to allow, must not be null

抛出:

IllegalArgumentException - if the suffix is null

SuffixFileFilter

public SuffixFileFilter(String suffix,
                        IOCase caseSensitivity)

Constructs a new Suffix file filter for a single extension specifying case-sensitivity.

参数:

suffix - the suffix to allow, must not be null

caseSensitivity - how to handle case sensitivity, null means case-sensitive

抛出:

IllegalArgumentException - if the suffix is null

从以下版本开始:

1.4

SuffixFileFilter

public SuffixFileFilter(String[] suffixes)

Constructs a new Suffix file filter for an array of suffixs.

The array is not cloned, so could be changed after constructing the instance. This would be inadvisable however.

参数:

suffixes - the suffixes to allow, must not be null

抛出:

IllegalArgumentException - if the suffix array is null

SuffixFileFilter

public SuffixFileFilter(String[] suffixes,
                        IOCase caseSensitivity)

Constructs a new Suffix file filter for an array of suffixs specifying case-sensitivity.

参数:

suffixes - the suffixes to allow, must not be null

caseSensitivity - how to handle case sensitivity, null means case-sensitive

抛出:

IllegalArgumentException - if the suffix array is null

从以下版本开始:

1.4

SuffixFileFilter

public SuffixFileFilter(List<String> suffixes)

Constructs a new Suffix file filter for a list of suffixes.

参数:

suffixes - the suffixes to allow, must not be null

抛出:

IllegalArgumentException - if the suffix list is null

ClassCastException - if the list does not contain Strings

SuffixFileFilter

public SuffixFileFilter(List<String> suffixes,
                        IOCase caseSensitivity)

Constructs a new Suffix file filter for a list of suffixes specifying case-sensitivity.

参数:

suffixes - the suffixes to allow, must not be null

caseSensitivity - how to handle case sensitivity, null means case-sensitive

抛出:

IllegalArgumentException - if the suffix list is null

ClassCastException - if the list does not contain Strings
