Parser::parse()

Node parse(TokenStream $stream, array $names = array())

Converts a token stream to a node tree.

The valid names is an array where the values are the names that the user can use in an expression.

If the variable name in the compiled PHP code must be different, define it as the key.

For instance, ['this' => 'container'] means that the variable 'container' can be used in the expression but the compiled code will use 'this'.

Parameters

TokenStream	$stream	A token stream instance
array	$names	An array of valid names

Return Value

Node	A node tree
