Constructor Detail

### Parameter

    public Parameter(ClassNode type,
                     String name)

### Parameter

    public Parameter(ClassNode type,
                     String name,
                     Expression defaultValue)

Method Detail

### toString

    public String toString()

  Overrides:
    `toString` in class `Object`

### getName

    public String getName()

  Description copied from interface: `Variable`
  the name of the variable

  Specified by:
    `getName` in interface `Variable`

### getType

    public ClassNode getType()

  Description copied from interface: `Variable`
  the type of the variable

  Specified by:
    `getType` in interface `Variable`

### setType

    public void setType(ClassNode type)

### hasInitialExpression

    public boolean hasInitialExpression()

  Description copied from interface: `Variable`
  returns true if there is an initialization expression

  Specified by:
    `hasInitialExpression` in interface `Variable`

### getInitialExpression

    public Expression getInitialExpression()

  Description copied from interface: `Variable`
  expression used to initialize the variable or null of there is no initialization.

  Specified by:
    `getInitialExpression` in interface `Variable`
  Returns:
    the default value expression for this parameter or null if no default value is specified

### setInitialExpression

    public void setInitialExpression(Expression init)

### isInStaticContext

### isClosureSharedVariable

    public boolean isClosureSharedVariable()

  Specified by:
    `isClosureSharedVariable` in interface `Variable`

### setClosureSharedVariable

    public void setClosureSharedVariable(boolean inClosure)

  Specified by:
    `setClosureSharedVariable` in interface `Variable`

### getOriginType

    public ClassNode getOriginType()

  Description copied from interface: `Variable`
  the type before wrapping primitives type of the variable

  Specified by:
    `getOriginType` in interface `Variable`
