Predicates

getCompilation

Gets the compilation that generated this diagnostic.

getFullMessage

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

getLocation

Gets the source location corresponding to the compiler message.

getMessage

Gets the error message text associated with this compiler diagnostic.

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.

getTag

Gets the error code for this compiler message.

hasTag

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

toString

Gets a textual representation of this element.

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
getEnclosingElement

Gets the closest Element enclosing this one.

from Element
getFile

Gets the primary file where this element occurs.

from Element
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
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.
