Class BlockStmt
A C/C++ block statement.
For example, the block from {
to }
in the following code:
{
int a;
int b = 1;
a = b;
}

Predicates
getADeclaration | Gets a child declaration of this block. |
getAPrimaryQlClass | Gets the name of a primary CodeQL class to which this element belongs. |
getAStmt | Gets a body statement of this block. |
getIndexOfStmt | Gets the index of the given statement within this block, indexed from 0. |
getLastStmt | Gets the last body statement of this block. |
getLastStmtIn | Gets the last body statement of this block. If this last statement is itself a block, returns the last statement of that block, and so on. |
getNumStmt | Gets the number of body statements in this block. |
getStmt | Gets the |
isEmpty | Holds if the block has no statements. |
mayBeGloballyImpure | Holds if it is possible that this statement is globally impure. |
mayBeImpure | Holds if it is possible that this statement is impure. If we are not sure, then it holds. |
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 |
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 |
getAChild | Gets a child of this statement. | from Stmt |
getAFalseSuccessor | Gets a node such that the control-flow edge | from ControlFlowNode |
getAPredecessor | Gets a direct predecessor of this control-flow node, if any. | from ControlFlowNode |
getASuccessor | Gets a direct successor of this control-flow node, if any. | from ControlFlowNode |
getATrueSuccessor | Gets a node such that the control-flow edge | from ControlFlowNode |
getAnAttribute | Gets an attribute of this statement, for example | from Stmt |
getAnImplicitDestructorCall | Gets a compiler-generated destructor call that is performed after this statement. | from Stmt |
getBasicBlock | Gets the | from ControlFlowNode |
getChild | Gets the | from Stmt |
getChildStmt | Gets a child statement of this statement. | from Stmt |
getControlFlowScope | Gets the function containing this control-flow node. | from Stmt |
getEnclosingBlock | Gets the nearest enclosing block of this statement in the source, if any. | from Stmt |
getEnclosingElement | Gets the closest | from Element |
getEnclosingFunction | Gets the enclosing function of this statement, if any. | from Stmt |
getEnclosingStmt | Gets the smallest statement containing this control-flow node. | from Stmt |
getFile | Gets the primary file where this element occurs. | from Element |
getFollowingStmt | Gets the statement following this statement in the same block, if any. | from Stmt |
getGeneratingMacro | Gets a macro invocation that generates this entire statement. | from Stmt |
getImplicitDestructorCall | Gets the | from Stmt |
getLocation | Gets the primary location of this element. | from Stmt |
getParent | Gets the parent of this statement, if any. | from Stmt |
getParentScope | Gets the parent scope of this | from Element |
getParentStmt | Gets the parent statement of this statement, if any. | from Stmt |
getPrimaryQlClasses | Gets a comma-separated list of the names of the primary CodeQL classes to which this element belongs. | from ElementBase |
hasChild | Holds if | from Stmt |
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 | from Element |
isCompilerGenerated | Holds if this statement was generated by the compiler. | from Stmt |
isCondition | Holds if this node is the top-level expression of a conditional statement, meaning that | from ControlFlowNode |
isFromTemplateInstantiation | Holds if this | from Element |
isFromUninstantiatedTemplate | Holds if this | 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 | from Element |
isPure | Holds if this statement is side-effect free (a conservative approximation; that is, it may be side-effect free even if this predicate doesn’t hold). | from Stmt |
