Method Detail

get

public static double get(net.sourceforge.pmd.lang.metrics.MetricKey<ASTAnyTypeDeclaration> key,
                         ASTAnyTypeDeclaration node)

Computes the standard value of the metric identified by its code on a class AST node.

Parameters:

key - The key identifying the metric to be computed

node - The node on which to compute the metric

Returns:

The value of the metric, or Double.NaN if the value couldn't be computed

get

public static double get(net.sourceforge.pmd.lang.metrics.MetricKey<ASTAnyTypeDeclaration> key,

                         net.sourceforge.pmd.lang.metrics.MetricOptions options)

Computes a metric identified by its code on a class AST node, possibly selecting a variant with the MetricOptions parameter.

Parameters:

key - The key identifying the metric to be computed

node - The node on which to compute the metric

options - The options of the metric

Returns:

The value of the metric, or Double.NaN if the value couldn't be computed

get
