ToSet

Convert a collection into a Set, deduplicating automatically.

Accepts an Array, a list-delimited String, an existing Set, a QueryColumn, an XML node, a bounded Range, or any value castable to a Set. When the value is already of the requested variant it is returned as-is; otherwise a new Set of the specified variant is created and populated.

Examples

Convert an array to a Set

Deduplicates the array elements and returns a BoxSet.

s = [ 1, 2, 2, 3 ].toSet();
writeOutput( s.size() );

Result: 3

Convert to a linked (insertion-ordered) Set

s = [ "c", "a", "b", "a" ].toSet( "linked" );
writeOutput( s.toArray().toString() );

Result: [c, a, b]

Convert to a sorted Set

s = [ 9, 1, 5, 3 ].toSet( "sorted" );
writeOutput( s.toArray().toString() );

Result: [1, 3, 5, 9]
