+ (Object) pointers_to_flat_array(pointers, include_indices = true)

Convert a Term pointer into a flat array without Hashes. If include_indices is set to false, node indices will be removed.

Examples:

Turn a pointer into a flat array with node indices preserved

OM.pointers_to_flat_array( [{:conference=>0}, {:role=>1}, :text] ) 
=> [:conference, 0, :role, 1, :text]

Remove node indices by setting include_indices to false

OM.pointers_to_flat_array( [{:conference=>0}, {:role=>1}, :text], false ) 
=> [:conference, :role, :text]

Parameters:

  • pointers (Array)

    array that you would pass into other Accessor methods

  • include_indices (Boolean) (defaults to: true)

    (default: true) if set to false, parent indices will be excluded from the array
