Scanner

class Scanner extends Reader[Token]

Scanner is essentially(*) a parser that produces Token's from a stream of characters. The tokens it produces are typically passed to parsers in TokenParsers.

Note: (*) Scanner is really a Reader' of Token's

Value Members

  1. def atEnd: Boolean

    true iff there are no more elements in this reader

    true iff there are no more elements in this reader

  2. def drop(n: Int): Reader[Token]

    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.

    definition classes: AnyRef ⇐ Any

  4. def first: Token

    Returns the first element of the reader

    Returns the first element of the reader

  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. def 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: Scanner

    Returns an abstract reader consisting of all elements except the first

    Returns an abstract reader consisting of all elements except the first

  9. def 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.

  10. def toString(): String

    Returns a string representation of the object

    Returns a string representation of the object.

    The default representation is platform dependent.
