Direct supertypes

Known direct subtypes

    Inherited predicates

    findRootCause

    Gets the source of this element: either itself or a macro that expanded to this element.

    from Element
    fromLibrary

    Holds if this element may be from a library.

    from Element
    fromSource

    Holds if this element may be from source. This predicate holds for all elements, except for those in the dummy file, whose name is the empty string. The dummy file contains declarations that are built directly into the compiler.

    from Element
    getAPrimaryQlClass

    Gets the name of a primary CodeQL class to which this element belongs.

    from ElementBase
    getCanonicalQLClass

    DEPRECATED: use getAPrimaryQlClass instead.

    from ElementBase
    getCompilation

    Gets the compilation that generated this diagnostic.

    from Diagnostic
    getEnclosingElement

    Gets the closest Element enclosing this one.

    from Element
    getFile

    Gets the primary file where this element occurs.

    from Element
    getFullMessage

    Gets the full error message text associated with this compiler diagnostic.

    from Diagnostic
    getLocation

    Gets the source location corresponding to the compiler message.

    from Diagnostic
    getMessage

    Gets the error message text associated with this compiler diagnostic.

    from Diagnostic
    getParentScope

    Gets the parent scope of this Element, if any. A scope is a Type (Class / Enum), a Namespace, a BlockStmt, a Function, or certain kinds of Statement.

    from Element
    getPrimaryQlClasses

    Gets a comma-separated list of the names of the primary CodeQL classes to which this element belongs.

    from ElementBase
    getSeverity

    Gets the severity of the message, on a range from 1 to 5: 1=remark, 2=warning, 3=discretionary error, 4=error, 5=catastrophic error.

    from Diagnostic
    getTag

    Gets the error code for this compiler message.

    from Diagnostic
    hasTag

    Holds if s is the error code for this compiler message.

    from Diagnostic
    isAffectedByMacro

    Holds if this element is affected in any way by a macro. All elements that are totally or partially generated by a macro are included, so this is a super-set of isInMacroExpansion.

    from Element
    isFromTemplateInstantiation

    Holds if this Element is a part of a template instantiation (but not the template itself).

    from Element
    isFromUninstantiatedTemplate

    Holds if this Element is part of a template template (not if it is part of an instantiation of template). This means it is represented in the database purely as syntax and without guarantees on the presence or correctness of type-based operations such as implicit conversions.

    from Element
    isInMacroExpansion

    Holds if this element comes from a macro expansion. Only elements that are entirely generated by a macro are included - for elements that partially come from a macro, see isAffectedByMacro.

    from Element
    toString

    Gets a textual representation of this element.
