Enum Constant Summary

Enum Constants
Enum Constant	Description
`ARRAY_LOAD`	A value read out of an array element by an array load.
`ARRAY_STORE`	A value written into an array element by an array store.
`CALL_ARG`	A value passed into an invocation as an argument, carrying it into the callee.
`CALL_RETURN`	A value produced by an invocation and flowing back out to the caller.
`DEF_USE`	A value flowing straight from the instruction that defines it to an instruction that reads it.
`FIELD_LOAD`	A value read out of an instance or static field by a field load.
`FIELD_STORE`	A value written into an instance or static field by a field store.
`OPERAND`	A value consumed as an operand of a computation, such as an arithmetic or comparison instruction.
`PHI_INPUT`	A value reaching a phi node along one of its incoming control flow edges.

- Method Detail
  - values
```
public static DataFlowEdgeType[] 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 (DataFlowEdgeType c : DataFlowEdgeType.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static DataFlowEdgeType 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
  - getDisplayName
```
public String getDisplayName()
```
    Returns:
    
    the display name
  - getDescription
```
public String getDescription()
```
    Returns:
    
    the description
  - propagatesTaint
```
public boolean propagatesTaint()
```
    Reports whether taint travels along this edge type.
    
    Returns:
    
    true - every data flow edge kind carries taint
