AbstractResource

public AbstractResource()

方法详细资料

exists

public boolean exists()

This implementation checks whether a File can be opened, falling back to whether an InputStream can be opened. This will cover both directories and content resources.

指定者:

exists 在接口中 org.frameworkset.util.io.Resource

isReadable

public boolean isReadable()

This implementation always returns true.

指定者:

isReadable 在接口中 org.frameworkset.util.io.Resource

isOpen

public boolean isOpen()

This implementation always returns false.

指定者:

isOpen 在接口中 org.frameworkset.util.io.Resource

getURL

public java.net.URL getURL()
                    throws java.io.IOException

This implementation throws a FileNotFoundException, assuming that the resource cannot be resolved to a URL.

指定者:

getURL 在接口中 org.frameworkset.util.io.Resource

抛出:

java.io.IOException

getURI

public java.net.URI getURI()
                    throws java.io.IOException

This implementation builds a URI based on the URL returned by getURL().

指定者:

getURI 在接口中 org.frameworkset.util.io.Resource

抛出:

java.io.IOException

getFile

public java.io.File getFile()
                     throws java.io.IOException

This implementation throws a FileNotFoundException, assuming that the resource cannot be resolved to an absolute file path.

指定者:

getFile 在接口中 org.frameworkset.util.io.Resource

抛出:

java.io.IOException

lastModified

public long lastModified()
                  throws java.io.IOException

This implementation checks the timestamp of the underlying File, if available.

指定者:

lastModified 在接口中 org.frameworkset.util.io.Resource

抛出:

java.io.IOException

另请参阅:

getFileForLastModifiedCheck()

contentLength

public long contentLength()
                   throws java.io.IOException

This implementation checks the timestamp of the underlying File, if available.

指定者:

contentLength 在接口中 org.frameworkset.util.io.Resource

抛出:

java.io.IOException

另请参阅:

getFile()

getFileForLastModifiedCheck

protected java.io.File getFileForLastModifiedCheck()
                                            throws java.io.IOException

Determine the File to use for timestamp checking.

The default implementation delegates to getFile().

返回:

the File to use for timestamp checking (never null)

抛出:

java.io.IOException - if the resource cannot be resolved as absolute file path, i.e. if the resource is not available in a file system

createRelative

public org.frameworkset.util.io.Resource createRelative(java.lang.String relativePath)
                                                 throws java.io.IOException

This implementation throws a FileNotFoundException, assuming that relative resources cannot be created for this resource.

指定者:

createRelative 在接口中 org.frameworkset.util.io.Resource

抛出:

java.io.IOException

getFilename

public java.lang.String getFilename()
                             throws java.lang.IllegalStateException

This implementation always throws IllegalStateException, assuming that the resource does not carry a filename.

指定者:

getFilename 在接口中 org.frameworkset.util.io.Resource

抛出:

java.lang.IllegalStateException

toString

public java.lang.String toString()

This implementation returns the description of this resource.

覆盖:

toString 在类中 java.lang.Object

另请参阅:

Resource.getDescription()

equals

public boolean equals(java.lang.Object obj)

This implementation compares description strings.

覆盖:

equals 在类中 java.lang.Object

另请参阅:

Resource.getDescription()

hashCode

public int hashCode()

This implementation returns the description's hash code.

覆盖:

hashCode 在类中 java.lang.Object

另请参阅:

Resource.getDescription()

release

public void release()

指定者:

release 在接口中 org.frameworkset.util.io.Resource

savetofile

public void savetofile(java.io.File destinctionFile,
                       ResourceHandleListener<AbstractResource> listener)
                throws java.io.IOException
