Direct supertypes

Indirect supertypes

Predicates

getOpcodeName	Gets the opcode name of this instruction, for example `ldnull`.
getType

Inherited predicates

canFlowNext	Holds if this instruction passes control flow into the next instruction.	from Instruction
flowsTo	Holds if this node flows to `sink` in zero or more steps.	from DataFlowNode
fromLibrary	Holds if this element is from an assembly.	from Element
fromSource	Holds if this element is from source code.	from Element
getALocalFlowSucc	Holds if this node flows to `sink` in one step. `tt` is the tainting that occurs during this step.	from DataFlowNode
getALocation	Gets a location of this element, which can include locations in both DLLs and source files.	from Instruction
getAPredecessor	Gets a predecessor of this node, if any.	from ControlFlowNode
getAPrimaryQlClass	Gets the name of a primary CodeQL class to which this element belongs.	from Element
getASuccessor	Gets a successor of this node, if any.	from ControlFlowNode
getASuccessorType	Gets a successor instruction to this instruction.	from Instruction
getAccess	Gets the declaration accessed by this instruction, if any.	from Instruction
getAnOperand	Gets an operand of this instruction, if any.	from ControlFlowNode
getEnclosingCallable	Gets the callable containing this expression.	from Expr
getExpr	Gets the expression being converted.	from Conversion
getExtra	Gets an extra field to display for this instruction, if any.	from Instruction
getFalseSuccessor	Gets a false successor of this node, if any.	from ControlFlowNode
getFile	Gets the file containing this element.	from Element
getHandler	Gets the `i`th handler that applies to this instruction. Indexed from 0.	from Instruction
getImplementation	Gets the method containing this instruction.	from Instruction
getIndex	Gets the index of this instruction. Instructions are sequenced from 0.	from Instruction
getLanguage	Gets the “language” of this program element, as defined by the extension of the filename. For example, C# has language “cs”, and Visual Basic has language “vb”.	from Element
getLocation		from Instruction
getMethod	Gets the method that contains this dataflow node.	from Instruction
getOpcode	Gets the opcode of this instruction.	from Instruction
getOperand	Gets an instruction that supplies the `i`th operand to this instruction. Note that this can be multi-valued.	from ControlFlowNode
getOperand	Gets the operand of this unary expression.	from UnaryExpr
getOperandType	Gets the type of the `i`th operand. Unlike `getOperand(i).getType()`, this predicate takes into account when there are multiple possible operands with different types.	from ControlFlowNode
getParent	The “parent” of a CIL expression is taken to be the instruction that consumes the value pushed by this instruction.	from Expr
getParentExpr	Gets an expression that consumes the output of this instruction on the stack.	from ControlFlowNode
getPopCount	Gets the number of items this node pops from the stack.	from UnaryExpr
getPrimaryQlClasses	Gets a comma-separated list of the names of the primary CodeQL classes to which this element belongs.	from Element
getPushCount	Gets the number of items this node pushes onto the stack. This value is either 0 or 1, except for the instruction `dup` which pushes 2 values onto the stack.	from Expr
getStackSizeAfter	Gets the stack size after this instruction.	from ControlFlowNode
getStackSizeBefore	Gets the stack size before this instruction.	from ControlFlowNode
getTrueSuccessor	Gets a true successor of this node, if any.	from ControlFlowNode
getValue	Gets the constant value of this expression, if any.	from Expr
hasValue	Holds if this expression has a value.	from Expr
isBranch	Holds if this control flow node has more than one successor.	from ControlFlowNode
isJoin	Holds if this control flow node has more than one predecessor.	from ControlFlowNode
toString		from Instruction
toStringExtra	Gets a more verbose textual representation of this instruction.	from Instruction
toStringWithTypes	Gets the full textual representation of this element, including type information.	from Element
