Input

trait Input extends AnyRef

An trait for objects that viewed as a sequence of bytes. For example InputStream and ReadableByteChannel could be an Input object.

Note: All collections returned are non-strict collections and each invocation of a method will typically open a new stream or channel. That behaviour can be overriden by the implementation but it is the default behaviour.

Default implementation is based on providing an implementation for bytesAsInts and all other methods are implemented using that method.

Abstract Value Members

  1. abstract def blocks(blockSize: Option[Int] = None): LongTraversable[ByteBlock]

    Read the input as blocks of bytes.

    Read the input as blocks of bytes. This method should be avoided unless the maximum performance is absolutely required because bytes provides very good performance and is a better API for most applications.

    However since it better reflects how data is read with most input sources (like InputStreams and ReadableByteChannels); blocks is slightly more performance than bytes and therefore can be used when performance is the most important consideration.

    blockSize

    block size can optionally be specified but the default is normally acceptable.

  2. abstract def bytes: LongTraversable[Byte]

    Obtains a Traversable for conveniently processing the resource as bytes.

    Obtains a Traversable for conveniently processing the resource as bytes.

    returns

    an non-strict traversable over all the bytes

  3. abstract def chars(implicit codec: Codec = Codec.default): LongTraversable[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

    returns

    an traversable of all the characters

  4. abstract def context: ResourceContext

    Get the Resource context that configures how the underlying resource is accessed

    Get the Resource context that configures how the underlying resource is accessed

    returns

    the associated ResourceContext

  5. abstract def size: Option[Long]

    The number of bytes that can be read from the underlying resource.

    The number of bytes that can be read from the underlying resource.

    if length == None then it is not possible to determine the number of bytes in advance.

  8. def bytesAsInts: LongTraversable[Int]

    Obtains a Traversable for conveniently processing the file as Ints.

    Obtains a Traversable for conveniently processing the file as Ints.

    Obtain an non-strict traversable for iterating through the lines 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.

    terminator

    The strategy for determining the end of line Default is to auto-detect the EOL

    includeTerminator

    if true then the line will end with the line terminator Default is false

    codec
