Detailed Description

A default path class for creation and manipulation of tree-based paths.

Member Function Documentation

append()

enzo::Path enzo::Path::append

(

const enzo::Path &

path

)

const

Returns a new path formed by appending the given path to this one.

The appended path may be a single component or a multi component path. A leading root delimiter on the appended path is ignored so it joins as a relative segment.

Parameters

path	The path to append to the end of this path.

Returns

A new Path with path appended.

getPrefixes()

std::vector< enzo::Path > enzo::Path::getPrefixes

(

)

const

Returns every ancestor path leading up to this path, ordered from shortest to longest. The path itself is not included.

E.g. the path "/World/Set/Props/Chair" returns /World /World/Set /World/Set/Props

hasPrefix()

bool enzo::Path::hasPrefix

(

const Path &

prefix

)

const

Checks if the Path has any additional prefixes.

Returns

true or false depending on whether the Path contains any prefixes.

increment()

enzo::Path enzo::Path::increment ( int increment = 1 ) const

virtual

Increments the numerical suffix of the path's name by a given amount.

A name with no numerical suffix is treated as 0, so the first increment produces a "1" suffix.

Parameters

increment

The amount to increment by. Defaults to 1.

Returns

A new Path with the incremented name.

isValid()

bool enzo::Path::isValid ( ) const

virtual

Runs every validation check and returns true if the path is fully valid.

A path is valid when it is non empty and every component is a valid name. The root path "/" is also valid.

Examples "/geo/mesh_01" valid "geo/mesh" valid relative path "/geo//mesh" invalid empty component "/geo/me!sh" invalid illegal character

See also

isValidName for the per component character rules.

Reimplemented in enzo::NetworkPath.

isValidFormatting()

bool enzo::Path::isValidFormatting ( const std::string & pathString )

static

Checks the path to make sure it fits the alphanumeric guidelines.

Parameters

pathString

A std::string representation of the path.

Returns

true or false based on whether the path formatting is valid or not.

See also

isValidName for the per component character rules.

isValidName()

bool enzo::Path::isValidName ( const std::string & name )

static

Checks the given name to make sure it fits the alphanumeric guidelines.

A valid name is non empty and contains only alphanumeric characters and underscores.

Parameters

name	The name that is being checked.

Returns

true or false based on whether the name is valid or not.

makeAbsolute()

enzo::Path enzo::Path::makeAbsolute

(

)

const

Converts a relative path to absolute, adding a root character.

Returns

A new Path object with the absolute path.

makeRelative()

enzo::Path enzo::Path::makeRelative

(

)

const

Converts an absolute path to relative, stripping the root character.

Returns

A new Path object with the new relative path.

makeRelativeTo()

enzo::Path enzo::Path::makeRelativeTo

(

const Path &

anchor

)

const

Makes a path relative to a given anchor path.

Parameters

anchor

Another Path object to act as an anchor, the method will return the original path if the anchor is the same as the path.

Returns

A Path object of the new relative path.
