class AnnotationExcluder(root: KtFile, excludes: List<Regex>, context: BindingContext)

Primary use case for an AnnotationExcluder is to decide if a KtElement should be excluded from further analysis. This is done by checking if a special annotation is present over the element.

data class Metric(val type: String, val value: Int, val threshold: Int, val isDouble: Boolean = false, val conversionFactor: Int = DEFAULT_FLOAT_CONVERSION_FACTOR)

abstract class MultiRule : BaseRule

Composite rule which delegates work to child rules. Can be used to combine different rules which do similar work like scanning the source code line by line to increase performance.

interface PropertiesAware

Properties holder. Allows to store and retrieve any data.

Link copied to clipboard

Allows to intercept detekt's result container by listening to the initial and final state and manipulate the reported findings.

Link copied to clipboard
abstract class Rule(val ruleSetConfig: Config = Config.empty, ruleContext: Context = DefaultContext()) : BaseRule, ConfigAware

A rule defines how one specific code structure should look like. If code is found which does not meet this structure, it is considered as harmful regarding maintainability or readability.

typealias RuleId = String

The type to use when referring to rule ids giving it more context then a String would.

Link copied to clipboard
class RuleSet(val id: RuleSetId, val rules: List<BaseRule>)

A rule set is a collection of rules and must be defined within a rule set provider implementation.

Link copied to clipboard
typealias RuleSetId = String
Link copied to clipboard
interface RuleSetProvider

A rule set provider, as the name states, is responsible for creating rule sets.

Link copied to clipboard

Context providing useful processing settings to initialize extensions.

Link copied to clipboard

Note: This will be replaced by SeverityLevel in future versions of detekt.

Link copied to clipboard

The severity level for each Issue. This will be printed to the output, such as XML or Sarif.

Link copied to clipboard
class SingleAssign<T : Any>

Allows to assign a property just once. Further assignments result in IllegalStateException's.

Link copied to clipboard
data class SourceLocation(val line: Int, val column: Int)

Stores line and column information of a location.

Link copied to clipboard
open class SplitPattern(text: String, delimiters: String = ",", removeTrailingAsterisks: Boolean = true)

Link copied to clipboard
abstract class ThresholdRule(config: Config, defaultThreshold: Int) : Rule

Link copied to clipboard
annotation class UnstableApi(val reason: String = "")

Experimental detekt api which may change on minor or patch versions.

Link copied to clipboard

ValuesWithReason is essentially the same as List of ValueWithReason. Due to type erasure we cannot use the list directly. Instances of this type should always created using the valuesWithReason factory method.

Link copied to clipboard
data class ValueWithReason(val value: String, val reason: String? = null)

A ValueWithReason represents a single configuration value that may have an explanation as to why it is used.

Properties

Link copied to clipboard

To represent a value of 0.5, use the metric value 50 and the conversion factor of 100. (50 / 100 = 0.5)

Functions

fun <T : Any> config(defaultValue: T): ReadOnlyProperty<ConfigAware, T>

fun <T : Any, U : Any> config(defaultValue: T, transformer: (T) -> U): ReadOnlyProperty<ConfigAware, U>

Creates a delegated read-only property that can be used in ConfigAware objects. The name of the property is the key that is used during configuration lookup. The value of the property is evaluated and transformed only once.

fun <T : Any> configWithFallback(fallbackProperty: KProperty0<T>, defaultValue: T): ReadOnlyProperty<ConfigAware, T>

Creates a delegated read-only property that can be used in ConfigAware objects. The name of the property is the key that is used during configuration lookup. If there is no such property, the value of the supplied fallbackProperty is also considered before using the defaultValue. The value of the property is evaluated only once.

fun <T : Any, U : Any> configWithFallback(fallbackProperty: KProperty0<U>, defaultValue: T, transformer: (T) -> U): ReadOnlyProperty<ConfigAware, U>

Creates a delegated read-only property that can be used in ConfigAware objects. The name of the property is the key that is used during configuration lookup.
