Results for: "pstore"

Returns the string value of this text node. This string is always escaped, meaning that it is a valid XML text node string, and all entities that can be escaped, have been inserted. This method respects the entity filter set in the constructor.

# Assume that the entity "s" is defined to be "sean", and that the
# entity "r" is defined to be "russell"
t = Text.new( "< & sean russell", false, nil, false, ['s'] )
t.to_s   #-> "&lt; &amp; &s; russell"
t = Text.new( "< & &s; russell", false, nil, false )
t.to_s   #-> "&lt; &amp; &s; russell"
u = Text.new( "sean russell", false, nil, true )
u.to_s   #-> "sean russell"

Escapes all possible entities

Unescapes all possible entities

Finds and returns the first node that matches the supplied xpath.

element

The context element

path

The xpath to search for. If not supplied or nil, returns the first node matching ‘*’.

namespaces

If supplied, a Hash which defines a namespace mapping.

variables

If supplied, a Hash which maps $variables in the query to values. This can be used to avoid XPath injection attacks or to automatically handle escaping string values.

XPath.first( node )
XPath.first( doc, "//b"} )
XPath.first( node, "a/x:b", { "x"=>"http://doofus" } )
XPath.first( node, '/book/publisher/text()=$publisher', {}, {"publisher"=>"O'Reilly"})

Performs a depth-first (document order) XPath search, and returns the first match. This is the fastest, lightest way to return a single result.

FIXME: This method is incomplete!

Builds a nodeset of all of the preceding nodes of the supplied node, in reverse document order

preceding

includes every element in the document that precedes this node,

except for ancestors

Reads tuple from the proxied TupleSpace. See TupleSpace#read.

Called by the TupleSpace to check if the object is still alive.

Contains all discovered TupleSpaces except for the primary.

Contains all discovered TupleSpaces except for the primary.

Has this tuple expired? (true/false).

A tuple has expired when its expiry timer based on the sec argument to initialize runs out.

Reset the expiry time according to sec_or_renewer.

nil

it is set to expire in the far future.

true

it has expired.

Numeric

it will expire in that many seconds.

Otherwise the argument refers to some kind of renewer object which will reset its expiry time.

Reads tuple, but does not remove it.
