This method is used to cast the receiver object to be of type T0.
This method is used to cast the receiver object to be of type T0.
Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expressionList(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as
part of compilation it is not possible to check whether the contents of the list are of the requested typed.

The eq method implements an [http://en.wikipedia.org/wiki/Equivalence_relation equivalence relation] on
non-null instances of AnyRef:
* It is reflexive: for any non-null instance x of type AnyRef, x.eq(x) returns true.
* It is symmetric: for any non-null instances x and y of type AnyRef, x.eq(y) returns true if and
only if y.eq(x) returns true.
* It is transitive: for any non-null instances x, y, and z of type AnyRef if x.eq(y) returns true and y.eq(z) returns true, then x.eq(z) returns true.
Additionally, the eq method has three other properties.
* It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of
x.eq(y) consistently returns true or consistently returns false.
* For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
* null.eq(null) returns true.
When overriding the equals or hashCode methods, it is important to ensure that their behavior is
consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they
should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

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 [http://en.wikipedia.org/wiki/Equivalence_relation equivalence

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
scala.Int
(o1.hashCode.equals(o2.hashCode)).

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

Process "include" directives in files, returning an iterator over lines from the flattened files.
The
grizzled.file.Includerclass can be used to process "include" directives within a text file, returning a file-like object. It also contains some utility functions that permit using include-enabled files in other contexts.Syntax
The include syntax is defined by a regular expression; any line that matches the regular expression is treated as an includedirective. The default regular expression,
^%include\s"([^"]+)"$matches include directives like this:Relative and local file references are relative to the including file or URL. That is, if an
Includeris processing file "/home/bmc/foo.txt" and encounters an attempt to include file "bar.txt", it will assume "bar.txt" is to be found in "/home/bmc".Similarly, if an
Includeris processing URL "http://localhost/bmc/foo.txt" and encounters an attempt to include file "bar.txt", it will assume "bar.txt" is to be found at "http://localhost/bmc/bar.txt".Nested includes are permitted; that is, an included file may, itself, include other files. The maximum recursion level is configurable and defaults to 100.
The include syntax can be changed by passing a different regular expression to the
Includerconstructor.Usage
This package provides an
Includerclass, which processes include directives in a file and behaves somewhat like a ScalaSource. See the class documentation for more details.The package also provides a
preprocess()convenience function, via a companion object, that can be used to preprocess a file; it returns the path to the resulting preprocessed file.Examples
Preprocess a file containing include directives, then read the result:
Use an include-enabled file with a Scala
