Tool for parsing ODL found at the top of .STS files.

OdlParser( )

getColumns

getColumns( JSONObject record, int startColumn, String name ) → int[]

Return the records of the object with the name, with nested object names delimited with a period (POSN is a vector, POSN.X is the component). This will return a two-element int array indicating the position: [start,endExclusive] for vectors, [col,col] for scalars or a vector component, or [-1,-1] when the name is not found. Zero is the first column.

Parameters

record - the JSON describing the file, or subset of the rows when startColumn is non-zero.
startColumn - starting column for the JSON.
name - of the object (POSN.X for example).

Returns:

[start,endExclusive] for vectors, [col,col] for scalars or a vector component, or [-1,-1] when the name is not found.
