IsIndirectlyUsedBy Method
NDepend.Reserved.CQLinq Namespace > ExtensionMethodsCQLinqDependency Class : IsIndirectlyUsedBy Method
This NDepend.CodeModel.IUsed object. A NDepend.CodeModel.IUsed object can be a NDepend.CodeModel.IAssembly, NDepend.CodeModel.INamespace, NDepend.CodeModel.IMember, NDepend.CodeModel.IType, NDepend.CodeModel.IMethod or NDepend.CodeModel.IField object.
The NDepend.CodeModel.ICodeElement.FullName of the code element user.
The string userCodeElementFullName can contain wildcard '*' characters but cannot be just a single wildcard string "*".
If one or several code elements are matched by userCodeElementFullName, this method has a used by any behavior.

If userCodeElementFullName matches several code elements of different kinds (like some assemblies and some namespaces) a compilation resolving error is emitted.
To solve this issue, the string can be prefixed with "ASSEMBLY:", "NAMESPACE:", "TYPE:", "METHOD:", "FIELD:", "PROPERTY:" or "EVENT:" to precise the kind of code element to match.
Alternatively, the string extensions methods MatchAssembly, MatchNamespace, MatchType, MatchMethod, MatchField, MatchProperty or MatchEvent can be used instead, to insert this prefix.

If no code element is matched by userCodeElementFullName, the CQLinq query will emit a compilation error, except if userCodeElementFullName is prefixed with "OPTIONAL:".
Alternatively, the string extensions methods AllowNoMatch can be used instead, to insert the "OPTIONAL:" prefix.
Returns true if usedCodeElement is, directly or indirectly, used by a NDepend.CodeModel.ICodeElement whose NDepend.CodeModel.ICodeElement.FullName is userCodeElementFullName. This method can only be called in a ICQLinqExecutionContext, otherwise the extension method NDepend.CodeModel.ExtensionMethodsSequenceUsage.NDepend.CodeModel.ExtensionMethodsSequenceUsage.IndirectlyUsedByAny<TUsed,TUser> must be called instead.
Syntax
[Extension()]
public static bool IsIndirectlyUsedBy( 
   IUsed usedCodeElement,
   string userCodeElementFullName
)

Parameters

usedCodeElement
This NDepend.CodeModel.IUsed object. A NDepend.CodeModel.IUsed object can be a NDepend.CodeModel.IAssembly, NDepend.CodeModel.INamespace, NDepend.CodeModel.IMember, NDepend.CodeModel.IType, NDepend.CodeModel.IMethod or NDepend.CodeModel.IField object.
userCodeElementFullName
The NDepend.CodeModel.ICodeElement.FullName of the code element user.
The string userCodeElementFullName can contain wildcard '*' characters but cannot be just a single wildcard string "*".
If one or several code elements are matched by userCodeElementFullName, this method has a used by any behavior.

If userCodeElementFullName matches several code elements of different kinds (like some assemblies and some namespaces) a compilation resolving error is emitted.
To solve this issue, the string can be prefixed with "ASSEMBLY:", "NAMESPACE:", "TYPE:", "METHOD:", "FIELD:", "PROPERTY:" or "EVENT:" to precise the kind of code element to match.
Alternatively, the string extensions methods MatchAssembly, MatchNamespace, MatchType, MatchMethod, MatchField, MatchProperty or MatchEvent can be used instead, to insert this prefix.

If no code element is matched by userCodeElementFullName, the CQLinq query will emit a compilation error, except if userCodeElementFullName is prefixed with "OPTIONAL:".
Alternatively, the string extensions methods AllowNoMatch can be used instead, to insert the "OPTIONAL:" prefix.

Return Value

userCodeElement being a NDepend.CodeModel.ICodeElement whose NDepend.CodeModel.ICodeElement.FullName is userCodeElementFullName:
Returns true if usedCodeElement is, directly or indirectly, used by a userCodeElement, otherwise returns false.
Exceptions
ExceptionDescription
This extension method cannot be called from a program consuming NDepend.API. In such context, the extension method NDepend.CodeModel.ExtensionMethodsSequenceUsage.NDepend.CodeModel.ExtensionMethodsSequenceUsage.IndirectlyUsedByAny<TUsed,TUser> must be called instead.
Remarks
If one or several code elements are matched by userCodeElementFullName, they will be listed in NDepend.CodeQuery.IQueryExecutionSuccessResult.TargetCodeElements.
In the context of a CQLinq compiled query, this method has a constant time complexity.
Requirements

Target Platforms: Windows 11, 10, 8, 7 and Linux, MacOS with net8.0, net7.0 or net6.0 installed
