DefaultFileRegion

public DefaultFileRegion(java.nio.channels.FileChannel file,
                 long position,
                 long count)

DefaultFileRegion

public DefaultFileRegion(java.nio.channels.FileChannel file,
                 long position,
                 long count,
                 boolean releaseAfterTransfer)

方法详细资料

getPosition

public long getPosition()

从接口复制的说明: FileRegion

Returns the offset in the file where the transfer began.

指定者:

getPosition 在接口中 FileRegion

getCount

public long getCount()

从接口复制的说明: FileRegion

Returns the number of bytes to transfer.

指定者:

getCount 在接口中 FileRegion

releaseAfterTransfer

public boolean releaseAfterTransfer()

transferTo

public long transferTo(java.nio.channels.WritableByteChannel target,
              long position)
                throws java.io.IOException

从接口复制的说明: FileRegion

Transfers the content of this file region to the specified channel.

指定者:

transferTo 在接口中 FileRegion

参数:

target - the destination of the transfer

position - the relative offset of the file where the transfer begins from. For example, 0 will make the transfer start from FileRegion.getPosition()th byte and FileRegion.getCount() - 1 will make the last byte of the region transferred.

抛出:

java.io.IOException

releaseExternalResources

public void releaseExternalResources()

从接口复制的说明: ExternalResourceReleasable

Releases the external resources that this object depends on. You should not call this method if the external resources (e.g. thread pool) are in use by other objects.

指定者:

releaseExternalResources 在接口中 ExternalResourceReleasable
