Enum Constant Summary

Enum Constants
Enum Constant	Description
`AST_EXPRESSION`	An expression in the recovered source tree, evaluating to a value.
`AST_STATEMENT`	A statement in the recovered source tree, executed for effect rather than for a value.
`BLOCK`	A basic block, a run of instructions entered only at its head.
`CALL_SITE`	A single invocation, the anchor interprocedural edges attach to.
`FIELD_REF`	A reference to a field, covering both reads and writes of it.
`INSTRUCTION`	A single IR instruction inside a block.
`LITERAL`	A compile-time constant operand, such as a number or string literal.
`LOCAL`	A local variable of the method, distinct from its declared parameters.
`METHOD`	A whole method, the root that its blocks and locals belong to.
`PARAMETER`	A formal parameter of the method, live from entry rather than assigned by a body instruction.
`PDG_ENTRY`	The synthetic root that unconditionally executed code hangs its control dependence from.
`PDG_EXIT`	The synthetic sink every path out of the method converges on.
`SDG_ACTUAL_IN`	An argument supplied at a call site, paired with the callee's formal-in.
`SDG_ACTUAL_OUT`	The value handed back to the caller at a call site, paired with the callee's formal-out.
`SDG_FORMAL_IN`	A value entering a method at its entry, the callee side of an actual-in.
`SDG_FORMAL_OUT`	A value leaving a method at its exit, the callee side of an actual-out.
`TYPE`	A named class or descriptor type mentioned by the code, not a value of that type.

- Method Detail
  - values
```
public static CPGNodeType[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (CPGNodeType c : CPGNodeType.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static CPGNodeType valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - getShortName
```
public String getShortName()
```
    Returns:
    
    the short name

    Returns:
    
    whether this is an IR-layer node type
  - isASTNode
```
public boolean isASTNode()
```
    Returns:
    
    whether this is an AST-layer node type
