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 Resource

isReadable

public boolean isReadable()

指定者:

isReadable 在接口中 Resource

getURI

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

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

指定者:

getURI 在接口中 Resource

抛出:

java.io.IOException

lastModified

public long lastModified()
                  throws java.io.IOException

checks the last modified time of the underlying File

指定者:

lastModified 在接口中 Resource

抛出:

java.io.IOException

getFile2Check

protected abstract java.io.File getFile2Check()
                                       throws java.io.IOException

Determine the File to use for timestamp checking.

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

toString

public java.lang.String toString()

覆盖:

toString 在类中 java.lang.Object
