## org.eclipse.jdt.core.dom
Class FieldDeclaration

    java.lang.Object
      org.eclipse.jdt.core.dom.ASTNode

              org.eclipse.jdt.core.dom.FieldDeclaration

public class FieldDeclaration
extends BodyDeclaration

Field declaration node type.

This kind of node collects several variable declaration fragments (`VariableDeclarationFragment`) into a single body declaration (`BodyDeclaration`), all sharing the same modifiers and base type.

     FieldDeclaration:
        [Javadoc] { ExtendedModifier } Type VariableDeclarationFragment
             { , VariableDeclarationFragment } ;

When a Javadoc comment is present, the source range begins with the first character of the "/**" comment delimiter. When there is no Javadoc comment, the source range begins with the first character of the initial modifier or type. The source range extends through the last character of the final ";".

Since:
  2.0

Field Detail

### JAVADOC_PROPERTY

    public static final ChildPropertyDescriptor JAVADOC_PROPERTY

  The "javadoc" structural property of this node type.

  Since:
    3.0

### MODIFIERS_PROPERTY

    public static final SimplePropertyDescriptor MODIFIERS_PROPERTY

  The "modifiers" structural property of this node type (JLS2 API only).

  Since:
    3.0

### MODIFIERS2_PROPERTY

    public static final ChildListPropertyDescriptor MODIFIERS2_PROPERTY

  The "modifiers" structural property of this node type (added in JLS3 API).

  Since:
    3.0

### TYPE_PROPERTY

    public static final ChildPropertyDescriptor TYPE_PROPERTY

  The "type" structural property of this node type.

  Since:
    3.0

### FRAGMENTS_PROPERTY

    public static final ChildListPropertyDescriptor FRAGMENTS_PROPERTY

  The "fragments" structural property of this node type).

  Since:
    3.0

Method Detail

### propertyDescriptors

    public static List propertyDescriptors(int apiLevel)

  Returns a list of structural property descriptors for this node type. Clients must not modify the result.

  Parameters:
    `apiLevel` - the API level; one of the `AST.JLS*` constants
  Returns:
    a list of property descriptors (element type: `StructuralPropertyDescriptor`)
  Since:
    3.0

### getType

    public Type getType()

  Returns the base type declared in this field declaration.

  N.B. The individual child variable declaration fragments may specify additional array dimensions. So the type of the variable are not necessarily exactly this type.

  Returns:
    the base type

### setType

    public void setType(Type type)

  Sets the base type declared in this field declaration to the given type.

  Parameters:
    `type` - the new base type
  Throws:
    `IllegalArgumentException` - if:
    - the node belongs to a different AST
    - the node already has a parent

### fragments

    public List fragments()

  Returns the live list of variable declaration fragments in this field declaration. Adding and removing nodes from this list affects this node dynamically. All nodes in this list must be `VariableDeclarationFragment`s; attempts to add any other type of node will trigger an exception.

  Returns:
    the live list of variable declaration fragments in this statement (element type: `VariableDeclarationFragment`)
