Method Detail

• getRepositoryUrl

  public String getRepositoryUrl()

  The base URL of the repository, e.g. "http://repo1.maven.org/maven2/". Unless the URL is unknown, it will be terminated by a trailing slash.

  Returns:

  The base URL of the repository or an empty string if unknown, never null.

• getResourceName

  public String getResourceName()

  The path of the resource relative to the repository's base URL, e.g. "org/apache/maven/maven/3.0/maven-3.0.pom".

  Returns:

  The path of the resource, never null.

• getFile

  public File getFile()

  Gets the local file being uploaded or downloaded. When the repository system merely checks for the existence of a remote resource, no local file will be involved in the transfer.

  Returns:

  The source/target file involved in the transfer or null if none.

• getContentLength

  public long getContentLength()

  The size of the resource in bytes. Note that the size of a resource during downloads might be unknown to the client which is usually the case when transfers employ compression like gzip. In general, the content length is not known until the transfer has started.

  Returns:

  The size of the resource in bytes or a negative value if unknown.

• setContentLength

  public TransferResource setContentLength(long contentLength)

  Sets the size of the resource in bytes.

  Parameters:

  contentLength - The size of the resource in bytes or a negative value if unknown.

  Returns:

  This resource for chaining, never null.

• getResumeOffset

  public long getResumeOffset()

  Gets the byte offset within the resource from which the download starts. A positive offset indicates a previous download attempt is being resumed, 0 means the transfer starts at the first byte.

  Returns:

  The zero-based index of the first byte being transferred, never negative.

• setResumeOffset

  public TransferResource setResumeOffset(long resumeOffset)

  Sets the byte offset within the resource at which the download starts.

  Parameters:

  resumeOffset - The zero-based index of the first byte being transferred, must not be negative.

  Returns:

  This resource for chaining, never null.

• getTransferStartTime

  public long getTransferStartTime()

  Gets the timestamp when the transfer of this resource was started.

  Returns:

  The timestamp when the transfer of this resource was started.

• getTrace

  public RequestTrace getTrace()

  Gets the trace information that describes the higher level request/operation during which this resource is transferred.

  Returns:

  The trace information about the higher level operation or null if none.

• toString

  public String toString()
