Constructor & Destructor Documentation

◆ FSobject()

utl::FSobject::FSobject ( const String path,
const Directory dir = nullptr 
)
inline

Constructor.

Parameters
pathpathname (relative to dir, if given)
dir(optional) parent directory

Definition at line 45 of file FSobject.h.

Member Function Documentation

◆ compare()

virtual int utl::FSobject::compare ( const Object rhs) const
virtual

Compare with another object.

If no overridden version succeeds in doing the comparison, then an attempt will be made to re-start the comparison process using one or both of the objects' keys. Usually, an override of compare() should call the superclass's compare() if it doesn't know how to compare itself with the rhs object.

See also
getKey
Returns
< 0 if self < rhs, 0 if self = rhs, > 0 if self > rhs
Parameters
rhsobject to compare with

Reimplemented from utl::Object.

Reimplemented in utl::Directory, and utl::Symlink.

◆ copy()

virtual void utl::FSobject::copy ( const Object rhs)
virtual

Copy another instance.

When you override copy(), you should usually call the superclass's copy().

Parameters
rhsobject to copy

Reimplemented from utl::Object.

Reimplemented in utl::Directory, and utl::Symlink.

◆ dump()

virtual void utl::FSobject::dump ( Stream os,
uint_t  level = uint_t_max 
) const
virtual

Dump a human-readable representation of self to the given output stream.

A common use of this is for debugging & testing.

Parameters
osstream to dump to
levellevel of 'verbosity' for the dump

Reimplemented from utl::Object.

Reimplemented in utl::Directory.

◆ getKey()

virtual const Object& utl::FSobject::getKey ( ) const
inlinevirtual

Get the key for this object.

The key for an object is used to re-start the comparison process when all overridden compare() have failed. Usually an object's key uniquely identifies the object, though it doesn't necessarily need to. By default, a class has no associated key.

See also
compare hasKey
Returns
object's key (= self if the object has no key)

Reimplemented from utl::Object.

Definition at line 58 of file FSobject.h.

References utl::ser_default, and utl::serialize().

◆ serialize()

virtual void utl::FSobject::serialize ( Stream stream,
uint_t  io,
uint_t  mode = ser_default 
)
virtual

Serialize to or from a stream.

This is the only virtual method for serialization. You must override this in any class that has data to be serialized, and ensure that the superclass's serialize() gets called.

Parameters
streamstream to serialize from/to
iosee utl::io_t
modesee utl::serialize_t

Reimplemented from utl::Object.

Reimplemented in utl::Directory, and utl::Symlink.

◆ toString()

virtual String utl::FSobject::toString ( ) const
inlinevirtual

Return a string representation of self.

Reimplemented from utl::Object.

Reimplemented in utl::Symlink.

Definition at line 66 of file FSobject.h.

◆ path()

Pathname utl::FSobject::path ( ) const

Get the path.

◆ relativePath()

Pathname utl::FSobject::relativePath ( ) const
inline

Get the relative path.

Definition at line 83 of file FSobject.h.

static

pathpathname (relative to dir, if given)
dir(optional) parent directory
