StreamReader

class StreamReader extends PagedSeqReader

A StreamReader reads from a character sequence, typically created as a PagedSeq from a java.io.Reader

NOTE: StreamReaders do not really fulfill the new contract for readers, which requires a source' CharSequence representing the full input. Instead source is treated line by line. As a consequence, regex matching cannot extend beyond a single line when a StreamReader are used for input. If you need to match regexes spanning several lines you should consider class PagedSeqReader instead.

Value Members

  1. def atEnd: Boolean

    true iff there are no more elements in this reader (except for trailing EofCh's)

    true iff there are no more elements in this reader (except for trailing EofCh's)

  2. def drop(n: Int): StreamReader

    Returns an abstract reader consisting of all elements except the first n elements

    Returns an abstract reader consisting of all elements except the first n elements.

  3. def equals(arg0: Any): Boolean

    This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence

    This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.

    The default implementations of this method is an equivalence relation:

    • It is reflexive: for any instance x of type Any, x.equals(x) should return true.
    • It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
    • It is transitive: for any instances x, y, and z of type AnyRef if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

    If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is often necessary to override hashCode to ensure that objects that are "equal" (o1.equals(o2) returns true) hash to the same Int (o1.hashCode.equals(o2.hashCode)).

    arg0

    the object to compare against this object for equality.

    returns

    true if the receiver object is equivalent to the argument; false otherwise.

  4. def first: Char

    Returns the first element of the reader, or EofCh if reader is at its end

    Returns the first element of the reader, or EofCh if reader is at its end

    definition classes: PagedSeqReaderReader
  5. def hashCode(): Int

    Returns a hash code value for the object

    Returns a hash code value for the object.

    The default hashing algorithm is platform dependent.

    Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

  6. val offset: Int

  7. def pos: Position

    The position of the first element in the reader

    The position of the first element in the reader

  8. def rest: StreamReader

    Returns a PagedSeqReader consisting of all elements except the first

    Returns a PagedSeqReader consisting of all elements except the first

  9. var source: CharSequence

    If this is a reader over character sequences, the underlying char sequence If not, throws a NoSuchMethodError exception

    If this is a reader over character sequences, the underlying char sequence If not, throws a NoSuchMethodError exception.

    definition classes: PagedSeqReaderReader
  10. def toString(): String

    Returns a string representation of the object

    Returns a string representation of the object.

    The default representation is platform dependent.
