trait SeqForwarder in scala.collection.generic

protected override abstract def underlying : Seq[A]

The iterable object to which calls are forwarded

Overrides: IterableForwarder.underlying

override def apply(i : Int) : A

Returns the elements at position `idx`

override def isDefinedAt(x : Int) : Boolean

Is this partial function defined for the index x?

override def length : Int

Returns the length of the sequence.

override def lengthCompare(l : Int) : Int

Result of comparing length with operand len. returns x where x < 0 iff this.length < len x == 0 iff this.length == len x > 0 iff this.length > len. The method as implemented here does not call length directly; its running time is O(length min len) instead of O(length). The method should be overwritten if computing length is cheap.

override def segmentLength(p : (A) => Boolean, from : Int) : Int

Returns length of longest segment starting from a start index `from` such that every element of the segment satisfies predicate `p`.

Notes: may not terminate for infinite-sized collections.
Parameters: p - the predicate; from - the start index

override def prefixLength(p : (A) => Boolean) : Int

Returns length of longest prefix of this seqence such that every element of the prefix satisfies predicate `p`.

Notes: may not terminate for infinite-sized collections.
Parameters: p - the predicate

override def indexWhere(p : (A) => Boolean, from : Int) : Int

Returns index of the first element starting from a start index satisying a predicate, or -1, if none exists.

Notes: may not terminate for infinite-sized collections.
Parameters: p - the predicate; from - the start index

override def indexOf[B >: A](elem : B, from : Int) : Int

Returns the index of the first occurence of the specified object in this sequence, starting from a start index, or -1, if none exists.

Notes: may not terminate for infinite-sized collections.
Parameters: elem - element to search for.

override def reverseIterator : Iterator[A]

The elements of this sequence in reversed order

override def startsWith[B](that : Seq[B], offset : Int) : Boolean

Checks whether the argument sequence is contained at the specified index within the receiver object. If the both the receiver object, this and the argument, that are infinite sequences this method may not terminate.

Returns: true if that is contained in this, at the specified index, otherwise false
See Also: String.startsWith

override def endsWith[B](that : Seq[B]) : Boolean

Returns: true if this sequence end with that sequence
See Also: String.endsWith

override def indexOfSeq[B >: A](that : Seq[B]) : Int

Returns: -1 if that not contained in this, otherwise the first index where that is contained.

override def contains(elem : Any) : Boolean

Tests if the given value elem is a member of this sequence.

Parameters: elem - element whose membership has to be tested.
Returns: true iff there is an element of this sequence which is equal (w.r.t. ==) to elem.

override def indices : Range

The range of all indices of this sequence.

Method Summary
`override def`	apply (i : Int) : A Returns the elements at position `idx`
`override def`	contains (elem : Any) : Boolean Tests if the given value `elem` is a member of this sequence.
`override def`	endsWith [B](that : Seq[B]) : Boolean
`override def`	indexOf [B >: A](elem : B, from : Int) : Int Returns the index of the first occurence of the specified object in this sequence, starting from a start index, or -1, if none exists.
`override def`	indexOfSeq [B >: A](that : Seq[B]) : Int
`override def`	indexWhere (p : (A) => Boolean, from : Int) : Int Returns index of the first element starting from a start index satisying a predicate, or -1, if none exists.
`override def`	indices : Range The range of all indices of this sequence.
`override def`	isDefinedAt (x : Int) : Boolean Is this partial function defined for the index `x`?
`override def`	length : Int Returns the length of the sequence.
`override def`	lengthCompare (l : Int) : Int Result of comparing `length` with operand `len`. returns `x` where `x < 0` iff `this.length < len` `x == 0` iff `this.length == len` `x > 0` iff `this.length > len`. The method as implemented here does not call length directly; its running time is O(length min len) instead of O(length). The method should be overwritten if computing length is cheap.
`override def`	prefixLength (p : (A) => Boolean) : Int Returns length of longest prefix of this seqence such that every element of the prefix satisfies predicate `p`.
`override def`	reverseIterator : Iterator[A] The elements of this sequence in reversed order
`override def`	segmentLength (p : (A) => Boolean, from : Int) : Int Returns length of longest segment starting from a start index `from` such that every element of the segment satisfies predicate `p`.
`override def`	startsWith [B](that : Seq[B], offset : Int) : Boolean Checks whether the argument sequence is contained at the specified index within the receiver object. If the both the receiver object, `this` and the argument, `that` are infinite sequences this method may not terminate.
