Modifier and Type	Method	Description
`void`	`accept(StyleVisitor visitor)`
`Expression`	`getDisplacementX()`	Returns an expression that computes a pixel offset from the geometry point.

```
static final Displacement DEFAULT

    Default Displacement instance.
  - NULL
```
static final Displacement NULL
```
    Null Displacement instance.
- Method Detail
  - getDisplacementX
```
Expression getDisplacementX()
```
    Returns an expression that computes a pixel offset from the geometry point. This offset point is where the text's anchor point gets located. If this expression is null, the default offset of zero is used.
    
    Specified by:
    
    getDisplacementX in interface Displacement
    
    Returns:
    
    Horizontal offeset
  - setDisplacementX
```
void setDisplacementX(Expression x)
```
    Sets the expression that computes a pixel offset from the geometry point.
  - setDisplacementY
```
void setDisplacementY(Expression y)
```
    Sets the expression that computes a pixel offset from the geometry point.
  - accept
```
void accept(StyleVisitor visitor)
