Field Detail

SOLVE_TABLE

public static final String SOLVE_TABLE

Name of the table to host intermediate solve results, in [schema_name.]table_name format, using standard name resolution rules and meeting table naming criteria. This table will contain the position and cost for each vertex in the graph. If the default value is used, a temporary table is created and deleted once the solution is calculated. The default value is ''.

IS_REPLICATED

public static final String IS_REPLICATED

If set to TRUE, replicate the SOLVE_TABLE. Supported values:

• TRUE
• FALSE

The default value is TRUE.

Constant Field Values

TRUE

public static final String TRUE

uses the solvers scheduled for 'shortest_path' and 'inverse_shortest_path' based on solve_direction

See Also:

Constant Field Values

FALSE

public static final String FALSE

uses the solvers 'priority_queue' and 'inverse_priority_queue' based on solve_direction

DATA_MIN_X

public static final String DATA_MIN_X

Lower bound for the x values. If not provided, it will be computed from the bounds of the input data.

Constant Field Values

DATA_MAX_X

public static final String DATA_MAX_X

Upper bound for the x values. If not provided, it will be computed from the bounds of the input data.

Constant Field Values

CONCAVITY_LEVEL

public static final String CONCAVITY_LEVEL

Factor to qualify the concavity of the isochrone curves. The lower the value, the more convex (with '0' being completely convex and '1' being the most concave). The default value is '0.5'. The minimum allowed value is '0'. The maximum allowed value is '1'.

Constant Field Values

USE_PRIORITY_QUEUE_SOLVERS

public static final String USE_PRIORITY_QUEUE_SOLVERS

sets the solver methods explicitly if true. Supported values:

• TRUE: uses the solvers scheduled for 'shortest_path' and 'inverse_shortest_path' based on solve_direction
• FALSE: uses the solvers 'priority_queue' and 'inverse_priority_queue' based on solve_direction

The default value is FALSE.

Constant Field Values

SOLVE_DIRECTION

public static final String SOLVE_DIRECTION

Specify whether we are going to the source node, or starting from it. Supported values:

• FROM_SOURCE: Shortest path to get to the source (inverse Dijkstra)
• TO_SOURCE: Shortest path to source (Dijkstra)

The default value is FROM_SOURCE.

See Also:

Constant Field Values

FROM_SOURCE

public static final String FROM_SOURCE
