构造器详细资料

DataSourceInputStream

public DataSourceInputStream(DataSource dataSource,
                             DataSpec dataSpec)

参数:

dataSource - The DataSource from which the data should be read.

dataSpec - The DataSpec defining the data to be read from dataSource.

方法详细资料

bytesRead

public long bytesRead()

Returns the total number of bytes that have been read or skipped.

open

public void open()
          throws java.io.IOException

Optional call to open the underlying DataSource.

Calling this method does nothing if the DataSource is already open. Calling this method is optional, since the read and skip methods will automatically open the underlying DataSource if it's not open already.

抛出:

java.io.IOException - If an error occurs opening the DataSource.

read

public int read()
         throws java.io.IOException

指定者:

read 在类中 java.io.InputStream

抛出:

java.io.IOException

read

public int read(byte[] buffer)
         throws java.io.IOException

覆盖:

read 在类中 java.io.InputStream

抛出:

java.io.IOException

read

public int read(byte[] buffer,
                int offset,
                int length)
         throws java.io.IOException

覆盖:

read 在类中 java.io.InputStream

抛出:

java.io.IOException

close

public void close()
           throws java.io.IOException

指定者:

close 在接口中 java.io.Closeable

指定者:

close 在接口中 java.lang.AutoCloseable

覆盖:

close 在类中 java.io.InputStream

抛出:

java.io.IOException
