Method Detail

setDefault

public ScopeConfiguratorBuilder<T> setDefault(T defaultScopeConfig)

Set the default scope config, which is returned by Function.apply(Object) if a InstrumentationScopeInfo does not match any conditions. If a default is not set, an SDK defined default is used.

addCondition

public ScopeConfiguratorBuilder<T> addCondition(java.util.function.Predicate<InstrumentationScopeInfo> scopePredicate,
                                                T scopeConfig)

Add a condition. Conditions are evaluated in order. The scopeConfig for the first match is returned by Function.apply(Object).

Parameters:

scopePredicate - predicate that InstrumentationScopeInfos are evaluated against

scopeConfig - the scope config to use when this condition is the first matching scopePredicate

nameMatchesGlob

public static java.util.function.Predicate<InstrumentationScopeInfo> nameMatchesGlob(java.lang.String globPattern)

Helper function for pattern matching InstrumentationScopeInfo.getName() against the globPattern.

globPattern may contain the wildcard characters * and ? with the following matching criteria:

• * matches 0 or more instances of any character
• ? matches exactly one instance of any character

nameEquals

public static java.util.function.Predicate<InstrumentationScopeInfo> nameEquals(java.lang.String scopeName)

Helper function for exact matching InstrumentationScopeInfo.getName() against the scopeName.
