getInputStream

public java.io.InputStream getInputStream()
                                   throws java.io.IOException

opens an InputStream for the given URL. It sets the "UseCaches" flag to false, mainly to avoid jar file locking on Windows.

抛出:

java.io.IOException

getURL

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

抛出:

java.io.IOException

getURI

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

This implementation returns the underlying URI directly, if possible.

指定者:

getURI 在接口中 Resource

覆盖:

getURI 在类中 AbstractResource

抛出:

java.io.IOException

getFile

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

This implementation returns a File reference for the underlying URL/URI, provided that it refers to a file in the file system.

抛出:

java.io.IOException

getFile2Check

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

determines the underlying File (or jar file, in case of a resource in a jar/zip).

指定者:

getFile2Check 在类中 AbstractResource

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

getResourceName

public java.lang.String getResourceName()

returns the name of the file that this URL refers to.

getResourceLocation

public java.lang.String getResourceLocation()

equals

public boolean equals(java.lang.Object obj)

覆盖:

equals 在类中 java.lang.Object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 java.lang.Object

getOutputStream

public java.io.OutputStream getOutputStream()
                                     throws java.io.IOException

opens an OutputStream for the given URL. It sets the "UseCaches" flag to false, mainly to avoid jar file locking on Windows.

抛出:

java.io.IOException
