Enum BytecodeEGWalker.StackValueCategoryConstraint

java.lang.Object

java.lang.Enum<BytecodeEGWalker.StackValueCategoryConstraint>

org.sonar.java.bytecode.se.BytecodeEGWalker.StackValueCategoryConstraint

All Implemented Interfaces:

Serializable, Comparable<BytecodeEGWalker.StackValueCategoryConstraint>, Constraint

Enclosing class:

BytecodeEGWalker

public static enum BytecodeEGWalker.StackValueCategoryConstraint
extends Enum<BytecodeEGWalker.StackValueCategoryConstraint>
implements Constraint

Because some instructions manipulate stack differently depending on the type of the value, we need this constraint to know category of the value see https://docs.oracle.com/javase/specs/jvms/se9/html/jvms-2.html#jvms-2.11.1 Table 2.11.1-B

Method Detail

values

public static BytecodeEGWalker.StackValueCategoryConstraint[] 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 (BytecodeEGWalker.StackValueCategoryConstraint c : BytecodeEGWalker.StackValueCategoryConstraint.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static BytecodeEGWalker.StackValueCategoryConstraint 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

valueAsString

public String valueAsString()

Specified by:

valueAsString in interface Constraint

Returns:

String representation of value encoded by constraint for purpose of flow message

copyOver

@Nullable
public Constraint copyOver(RelationalSymbolicValue.Kind kind)

Description copied from interface: Constraint

Return constraint which should be applied to the rhs of the relation, if this constraint is set on the lhs of the relation.

Specified by:

copyOver in interface Constraint

Parameters:

kind - kind of relation over which constraint is copied

Returns:

constraint to be set on rhs, null if no constraint should be set
