InputResource

trait InputResource [+R <: Closeable] extends Resource[R] with Input with ResourceOps[R, InputResource[R]]

An Resource object that is a also an Input. This trait adds methods for converting between common io types such as to a ReaderResource or ReadableByteChannelResource

R

the type of underlying resource that is created

  1. def appendCloseAction [B >: R] (newAction: CloseAction[B]): InputResource[R]

    Add a CloseAction to the end of the CloseAction queue (the last action executed).

    Add a CloseAction to the end of the CloseAction queue (the last action executed).

    newAction

    The new action to append

    returns

  3. def chars (implicit codec: Codec = Codec.default): ResourceView[Char]

    The characters in the object.

    The characters in the object.

    If the codec is not the same as the source codec (the codec of the underlying data) then the characters will converted to the desired codec.

    codec

    The codec representing the desired encoding of the characters @return an traversable of all the characters

  4. def inputStream : InputResource[InputStream]

    Obtain the InputStreamResource(typically) version of this object.

    Obtain the InputStreamResource(typically) version of this object.

    returns

    the InputStreamResource(typically) version of this object.

    abstract
  5. def open (): OpenedResource[R]

    Creates a new instance of the underlying resource (or opens it).

    Creates a new instance of the underlying resource (or opens it). Sometimes the code block used to create the Resource is non-reusable in which case this Resource can only be used once. This is not recommended. When creating a resource it is recommended to pass the code block for creating the resource to the resource so that the resource can be reused. Of course this is not always possible

    This method should only be used with care in cases when Automatic Resource Management cannot be used because the InputStream must be closed manually.

    This is public only to permit interoperability with certain Java APIs. A better pattern of use should be:

    resource.acquireFor {
      // call java API
    }
    

    or

    val calculatedResult = resource.acquireAndGet {
      // cal java API that returns a result
    }
    
    returns

    the actual resource that has been opened

    output sink to copy the data to

    finalize

    do not forward request to output's copyFrom method. Often only one end of the transaction will know how to efficiently transfer data so a common pattern is to check the output and see if the type of the Output object is a known type. If not then the output object will be sent the request. However, to prevent an infinite loop the finalize will be set to true so the request is not then forwarded back to copyTo
