Class CilGraphNode
Represents a node in the CIL graph. A node describes an instruction and its connection with other instructions
Inherited Members
Namespace: CilTools.BytecodeAnalysis
Assembly: CilTools.BytecodeAnalysis.dll
Syntax
public class CilGraphNodeRemarks
See CilGraph class documentation for more information about CIL graphs.
Constructors
CilGraphNode()
Creates new CilGraphNode object
Declaration
protected CilGraphNode()Properties
BranchTarget
Gets a reference to the node that represents instruction which is a target of the current instruction, if applicable
Declaration
public CilGraphNode BranchTarget { get; }Property Value
| Type | Description |
|---|---|
| CilGraphNode |
Remarks
Branch target is an instruction which would be called after current one if the condition for jump instruction is met. For non-jump instructions, the value is null.
Instruction
Gets CIL instruction associated with this node
Declaration
public CilInstruction Instruction { get; }Property Value
| Type | Description |
|---|---|
| CilInstruction |
Name
Gets label name associated with this node
Declaration
public string Name { get; }Property Value
| Type | Description |
|---|---|
| System.String |
Remarks
Label names are assigned to instruction that serve as branch targets for convenience. If the instruction is not used as target, the value is empty string.
Next
Gets a reference to the node that represents instruction directly following current instruction in the method bytecode
Declaration
public CilGraphNode Next { get; }Property Value
| Type | Description |
|---|---|
| CilGraphNode |
Remarks
Next instruction will be normally executed after current one, unless it is a jump instruction and the condition for jump is met. For the last instruction of the method body, the value is null.
Previous
Gets a reference to the node that represents instruction directly preceding current instruction in the method bytecode
Declaration
public CilGraphNode Previous { get; }Property Value
| Type | Description |
|---|---|
| CilGraphNode |
Remarks
For the first instruction in the method body, the value is null.
Methods
GetExceptionBlocks()
Gets an array of exception handling blocks in which this node is enclosed
Declaration
public ExceptionBlock[] GetExceptionBlocks()Returns
| Type | Description |
|---|---|
| ExceptionBlock[] | An array of exception blocks, or an empty array if there are none |
GetSwitchTargets()
Gets an array of nodes that represents the jump table of the switch instruction, if applicable
Declaration
public CilGraphNode[] GetSwitchTargets()Returns
| Type | Description |
|---|---|
| CilGraphNode[] |
Remarks
Jump table is the sequence of instructions corresponding to the switch instruction. When runtime processes switch instruction, it will transfer control to one of the instructions based on the value pushed to the stack. For non-switch instructions, returns an empty array.
ToString()
Returns text representation of this node as a line of CIL code
Declaration
public override string ToString()Returns
| Type | Description |
|---|---|
| System.String | String that contatins a text representation of this node |
