Method Detail

renderInstaller

public static java.lang.String renderInstaller(java.lang.Class<FeatureInstaller> type,
                                               java.util.List<java.lang.String> markers)

Render installer line. Assuming installer class always ends with Installer and by removing this postfix and converting rest to lower case we can get human readable installer name. Result may be worse for multi-word cases, but anyway it's pretty readable.

Format: human-readable-installer-name (installer-class) *markers.

Parameters:

type - installer class

markers - markers

Returns:

rendered installer line

renderDisabledInstaller

public static java.lang.String renderDisabledInstaller(java.lang.Class<FeatureInstaller> type)

Renders disabled installer line. The same as installer line, but with '-' before installer name and without markers.

Parameters:

type - disabled installer class

Returns:

rendered disabled installer line

renderClassLine

public static java.lang.String renderClassLine(java.lang.Class<?> type,
                                               java.util.List<java.lang.String> markers)

Renders class as: class-simple-name (class-package) *markers. For anonymous class simple name will be Class$1.

Parameters:

type - class

markers - markers

Returns:

rendered class line

renderClassLine

public static java.lang.String renderClassLine(java.lang.Class<?> type,
