ABOUT

Take a string description, parse it, provide frontend methods.

PUBLIC METHODS

new ( %args )

Constructor; creates instance.

Args:

match( $data )

Returns an array of all values in $data that match the Path object.

matchr( $data )

Returns an array ref of all values in $data that match the Path object.

INTERNAL METHODS

op_match( $self, $data )

This sub/method is bound as the overloading function for ~~.

quoted

Checks whether a path part starts with quotes.

unquote

Removes surrounding quotes.

unescape

Converts backslashed characters into their non-backslashed form.

_build__steps

This method is essentially the DPath parser as it tokenizes the path into single steps whose later execution is the base functionality of the whole DPath module.

path

_steps

Attribute / accessor.

give_references

Attribute / accessor.

aliased classes

That's just to make Pod::Coverage happy which does not handle aliased modules.
