values
public static LongConstant[] 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 (LongConstant c : LongConstant.values()) System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in the order they are declared
-
valueOf
public static LongConstant valueOf(java.lang.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:
java.lang.IllegalArgumentException
- if this enum type has no constant with the specified namejava.lang.NullPointerException
- if the argument is null
-
forValue
public static StackManipulation forValue(long value)
Creates a stack manipulation for loading along
value onto the operand stack.- Parameters:
value
- Thelong
value to load onto the stack.- Returns:
- A stack manipulation for loading the given
long
value.
-
isValid
public boolean isValid()
Determines if this stack manipulation is valid.- Specified by:
isValid
in interfaceStackManipulation
- Returns:
- If
false
, this manipulation cannot be applied and should throw an exception.
-
apply
public StackManipulation.Size apply(org.objectweb.asm.MethodVisitor methodVisitor, Implementation.Context implementationContext)
Applies the stack manipulation that is described by this instance.- Specified by:
apply
in interfaceStackManipulation
- Parameters:
methodVisitor
- The method visitor used to write the method implementation to.implementationContext
- The context of the current implementation.- Returns:
- The changes to the size of the operand stack that are implied by this stack manipulation.
