org.eclipse.jdt.core.dom
Class ImportDeclaration

java.lang.Object
  extended by 

org.eclipse.jdt.core.dom.ASTNode
      extended by 
org.eclipse.jdt.core.dom.ImportDeclaration

public class ImportDeclaration
extends ASTNode

Import declaration AST node type. For JLS2:

    import [ static ] Name [ . * ] ;
 

Since:
2.0
Restriction:
This class is not intended to be instantiated by clients.

Field Summary
static  ChildPropertyDescriptor NAME_PROPERTY
          The "name" structural property of this node type.
static  SimplePropertyDescriptor ON_DEMAND_PROPERTY
          The "onDemand" structural property of this node type.
static  SimplePropertyDescriptor STATIC_PROPERTY
          The "static" structural property of this node type (added in JLS3 API).

Field Detail

NAME_PROPERTY

public static final 
ChildPropertyDescriptor NAME_PROPERTY
The "name" structural property of this node type.

Since:
3.0

ON_DEMAND_PROPERTY

public static final 
SimplePropertyDescriptor ON_DEMAND_PROPERTY
The "onDemand" structural property of this node type.

Since:
3.0

STATIC_PROPERTY

public static final 
SimplePropertyDescriptor STATIC_PROPERTY
The "static" structural property of this node type (added in JLS3 API).

Since:
3.1
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

getName

public 
Name getName()
Returns the name imported by this declaration.

For a regular on-demand import, this is the name of a package. For a static on-demand import, this is the qualified name of a type. For a regular single-type import, this is the qualified name of a type. For a static single-type import, this is the qualified name of a static member of a type.

Returns:
the imported name node

setName

public void setName(
Name name)
Sets the name of this import declaration to the given name.

For a regular on-demand import, this is the name of a package. For a static on-demand import, this is the qualified name of a type. For a regular single-type import, this is the qualified name of a type. For a static single-type import, this is the qualified name of a static member of a type.

Parameters:
name - the new import name
Throws:
IllegalArgumentException - if:
  • the node belongs to a different AST
  • the node already has a parent

isOnDemand

public boolean isOnDemand()
Returns whether this import declaration is an on-demand or a single-type import.

Returns:
true if this is an on-demand import, and false if this is a single type import

setOnDemand

public void setOnDemand(boolean onDemand)
Sets whether this import declaration is an on-demand or a single-type import.

Parameters:
onDemand - true if this is an on-demand import, and false if this is a single type import

isStatic

public boolean isStatic()
Returns whether this import declaration is a static import (added in JLS3 API).

Returns:
true if this is a static import, and false if this is a regular import
Throws:
UnsupportedOperationException - if this operation is used in a JLS2 AST
Since:
3.1

setStatic

public void setStatic(boolean isStatic)
Sets whether this import declaration is a static import (added in JLS3 API).

Parameters:
isStatic - true if this is a static import, and false if this is a regular import
Throws:
UnsupportedOperationException - if this operation is used in a JLS2 AST
Since:
3.1

resolveBinding

public 
IBinding resolveBinding()
Resolves and returns the binding for the package, type, field, or method named in this import declaration.

The name specified in a non-static single-type import can resolve to a type (only). The name specified in a non-static on-demand import can itself resolve to either a package or a type. For static imports (introduced in JLS3), the name specified in a static on-demand import can itself resolve to a type (only). The name specified in a static single import can resolve to a type, field, or method; in cases where the name could be resolved to more than one element with that name (for example, two methods both named "max", or a method and a field), this method returns one of the plausible bindings.

Note that bindings are generally unavailable unless requested when the AST is being built.

Returns:
a package, type, field, or method binding, or null if the binding cannot be resolved
