METHODS
Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class.
"new ( $left, $right )"
Returns a new Union structure.
"construct_args"
Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern.
"first"
Returns the first pattern (LHS) of the union.
"second"
Returns the second pattern (RHS) of the union.
"patterns"
Returns the two patterns belonging to the UNION pattern.
"sse"
Returns the SSE string for this algebra expression.
"as_sparql"
Returns the SPARQL string for this algebra expression.
"as_hash"
Returns the query as a nested set of plain data structures (no objects).
"type"
Returns the type of this algebra expression.
"referenced_variables"
Returns a list of the variable names used in this algebra expression.
"potentially_bound"
Returns a list of the variable names used in this algebra expression that will bind values during execution.
"definite_variables"
Returns a list of the variable names that will be bound after evaluating this algebra expression.

Hi All,
Query 1 :
I want to know how we can get a count of multipe occurrences of a particular expression in another string.
For Eg. If my string is " 12" and i need to count the number of spaces preceeding 12
