Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`boolean`	`equals(Object obj)`
`Description`	`getDescription()` Returns the description of this symbolizer.
`Expression`	`getGeometry()` This defines the geometry to be used for styling.
`String`	`getGeometryPropertyName()` A shortcut to get the geometry property name in the case the geometry expression is a PropertyName.
`String`	`getName()` Returns a name for this symbolizer.
`Map<String,String>`	`getOptions()` Map of vendor options for the symbolizer.
`Unit<Length>`	`getUnitOfMeasure()` Returns a measure unit.
`int`	`hashCode()`
`boolean`	`hasOption(String key)` Determines if a vendor option with the specific key has been set on this symbolizer.
`void`	`setDescription(Description description)` Tile and Abstract of Symbolzer.
`void`	`setGeometry(Expression geometry)` Sets the expression used for styling.
`void`	`setGeometryPropertyName(String geometryPropertyName)` A shortcut to define the geometry expression as a `PropertyName` Typically, features only have one geometry so, in general, the need to select one is not required.
`void`	`setName(String name)` Name of symbolizer; not always human readable.

  - getDescription
```
public Description getDescription()
```
    Description copied from interface: Symbolizer
    
    Returns the description of this symbolizer.
    
    Specified by:
    
    getDescription in interface Symbolizer
    
    Returns:
    
    Description with usual informations used for user interfaces.
  - setDescription
```
public void setDescription(Description description)
```
    Description copied from interface: Symbolizer
    
    Tile and Abstract of Symbolzer.
  - getName
```
public String getName()
```
    Description copied from interface: Symbolizer
    
    Returns a name for this symbolizer. This can be any string that uniquely identifies this style within a given canvas. It is not meant to be human-friendly. (The "title" property is meant to be human friendly.)
    
    Specified by:
    
    getName in interface Symbolizer
    
    Returns:
    
    a name for this style.
  - setName
```
public void setName(String name)
```
    Description copied from interface: Symbolizer
    
    Name of symbolizer; not always human readable.
    Please consider getDescription().getTitle() as an alternative if presenting this symbolizer in a user interface.
  - setUnitOfMeasure
```
public void setUnitOfMeasure(Unit<Length> uom)
```
    Description copied from interface: Symbolizer
    Defines a measure unit for the symbolizer. This parameter is inherited from GML. Renderers shall use the unit to correctly render symbols.
    Recommended uom definitions are :
    - metre
    - foot
    - pixel
    Parameters:
    
    uom - can be null, which indicates usage of the pixel unit.
  - getUnitOfMeasure
```
public Unit<Length> getUnitOfMeasure()
```
    Description copied from interface: Symbolizer
    Returns a measure unit. This parameter is inherited from GML. Renderers shall use the unit to correctly render symbols.
    Recommended uom definitions are :
    - metre
    - foot
    - pixel
    Specified by:
    
    getUnitOfMeasure in interface Symbolizer
    
    Returns:
    
    can be null. If the unit is null than we shall use a the pixel unit
  - getGeometry
```
public Expression getGeometry()
```
    Description copied from interface: Symbolizer
    
    This defines the geometry to be used for styling.
    The property is optional and if it is absent (null) then the "default" geometry property of the feature should be used.
    Typically, features only have one geometry so, in general, the need to select one is not required.
    The expression can also build a new geometry out of existing attributes or transform an existing geometry. For geometry transformations that do change the geometry locations or that make up geometries out of non geometric attributes it is advised that the Expression implements the SpatialTransformationFunction interface
  - setGeometry
```
public void setGeometry(Expression geometry)
```
    Description copied from interface: Symbolizer
    
    Sets the expression used for styling. See Symbolizer.getGeometry() for further details.
  - getGeometryPropertyName
```
public String getGeometryPropertyName()
```
    Description copied from interface: Symbolizer
    
    A shortcut to get the geometry property name in the case the geometry expression is a PropertyName. In case the geometry expression is null, and in the case the geometry expression is not a PropertyName, this method will return null.
    
    Specified by:
    
    getGeometryPropertyName in interface Symbolizer
    
    Returns:
    
    Geometry attribute name, or null to indicate default geometry
  - setGeometryPropertyName
```
public void setGeometryPropertyName(String geometryPropertyName)
```
    Description copied from interface: Symbolizer
    
    A shortcut to define the geometry expression as a PropertyName Typically, features only have one geometry so, in general, the need to select one is not required. Note: this moves a little away from the SLD spec which provides an XPath reference to a Geometry object, but does follow it in spirit.
  - hasOption
```
public boolean hasOption(String key)
```
    Description copied from interface: Symbolizer
    
    Determines if a vendor option with the specific key has been set on this symbolizer.
  - getOptions
```
public Map<String,String> getOptions()
```
    Description copied from interface: Symbolizer
    
    Map of vendor options for the symbolizer.
    Client code looking for the existence of a single option should use Symbolizer.hasOption(String)
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - equals
```
public boolean equals(Object obj)
```
    Overrides:
    
    equals in class Object
