class OffsetPosition

[source: scala/util/parsing/input/OffsetPosition.scala]

case class OffsetPosition(val source : java.lang.CharSequence, val offset : Int)
extends Position with Product

OffsetPosition is a standard class for positions represented as offsets into a source ``document''.

Parameters
source - The source document
offset - The offset indicating the position

Method Summary
override def < (that : Position) : Boolean
Compare this position to another, by first comparing their line numbers, and then -- if necessary -- using the columns to break a tie.
override def canEqual (arg0 : Any) : Boolean
An equality helper method to assist in maintaining reflexivity in the face of subtyping. For more, see http://www.artima.com/lejava/articles/equality.html
def column : Int
The column number referred to by the position; column numbers start at 1
override def equals (arg0 : Any) : Boolean
This method is used to compare the receiver object (this) with the argument object (arg0) for equivalence.
override def hashCode : Int
Returns a hash code value for the object.
def line : Int
The line number referred to by the position; line numbers start at 1
def lineContents : java.lang.String
The contents of the line numbered `lnum' (must not contain a new-line character).
override def productArity : Int
return k for a product A(x_1,...,x_k)
override def productElement (arg0 : Int) : Any
for a product A(x_1,...,x_k), returns x_(n+1) for 0 <= n < k
override def productPrefix : java.lang.String
By default the empty string. Implementations may override this method in order to prepend a string prefix to the result of the toString methods.
override def toString : java.lang.String
Returns a string representation of the `Position', of the form `line.column'

Method Details
def line : Int
The line number referred to by the position; line numbers start at 1
Overrides
Position.line

def column : Int
The column number referred to by the position; column numbers start at 1
Overrides
Position.column

def lineContents : java.lang.String
The contents of the line numbered `lnum' (must not contain a new-line character).
Parameters
lnum - a 1-based integer index into the `document'
Returns
the line at `lnum' (not including a newline)
Overrides
Position.lineContents

override def toString : java.lang.String
Returns a string representation of the `Position', of the form `line.column'
Overrides
Position.toString

override def <(that : Position) : Boolean
Compare this position to another, by first comparing their line numbers, and then -- if necessary -- using the columns to break a tie.
Parameters
`that' - a `Position' to compare to this `Position'
Returns
true if this position's line or (in case of a tie wrt. line numbers) its column is smaller than the corresponding components of `that'
Overrides
Position.<

override def hashCode : Int
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.

Returns
the hash code value for the object.


override def equals(arg0 : Any) : Boolean
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)).

Parameters
arg0 - the object to compare against this object for equality.
Returns
true if the receiver object is equivalent to the argument; false otherwise.

Returns
The element n elements after the first element
