from AstNode
getAPrimaryQlClass

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

from TryExpr
getAnAttr

Gets any of the attrs of this try expression.

from TryExpr
getAttr

Gets the indexth attr of this try expression (0-based).

from TryExpr
getEnclosingCallable

Gets the immediately enclosing callable of this node, if any.

from AstNode
getEnclosingCfgScope

Gets the CFG scope that encloses this node, if any.

from AstNode
getExpr

Gets the expression of this try expression, if it exists.

from TryExpr
getFile

Gets the primary file where this element occurs.

from Locatable
getLocationfrom Locatable
getNumberOfAttrs

Gets the number of attrs of this try expression.

from TryExpr
getParentNode

Gets the nearest enclosing parent of this node, which is also an AstNode, if any.

from AstNode

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

from Element
getResolveStep

from Element
hasExpr

Holds if getExpr() exists.

from TryExpr
isFromMacroExpansion

Holds if this node exists only as the result of a macro expansion.

from AstNode
isInMacroExpansion

Holds if this node is inside a macro expansion.

from AstNode
isUnknownfrom Element
resolve

Gets the element that should substitute this element in the explicit AST, applying getResolveStep transitively.

toString

Gets the string representation of this element.
