Class NativeJavaPackage

java.lang.Object

org.mozilla.javascript.ScriptableObject

org.mozilla.javascript.NativeJavaPackage

All Implemented Interfaces:

java.io.Serializable, ConstProperties, DebuggableObject, Scriptable

Direct Known Subclasses:

NativeJavaTopPackage

public class NativeJavaPackage
extends ScriptableObject

This class reflects Java packages into the JavaScript environment. We lazily reflect classes and subpackages, and use a caching/sharing system to ensure that members reflected into one JavaPackage appear in all other references to the same package (as with Packages.java.lang and java.lang).

Constructor Detail

NativeJavaPackage

public NativeJavaPackage(java.lang.String packageName,
                 java.lang.ClassLoader classLoader)

Deprecated. NativeJavaPackage is an internal class, do not use it directly.

public NativeJavaPackage(java.lang.String packageName)

Deprecated. NativeJavaPackage is an internal class, do not use it directly.

Method Detail

getClassName

public java.lang.String getClassName()

Description copied from class: ScriptableObject

Return the name of the class. This is typically the same name as the constructor. Classes extending ScriptableObject must implement this abstract method.

Specified by:

getClassName in interface Scriptable

Specified by:

getClassName in class ScriptableObject

has

public boolean has(java.lang.String id,
          Scriptable start)

Description copied from class: ScriptableObject

Returns true if the named property is defined.

Specified by:

has in interface Scriptable

Overrides:

has in class ScriptableObject

Parameters:

id - the name of the property

start - the object in which the lookup began

Returns:

true if and only if the property was found in the object

See Also:

Scriptable.get(String, Scriptable), ScriptableObject.getProperty(Scriptable, String)

has

public boolean has(int index,
          Scriptable start)

Description copied from class: ScriptableObject

Returns true if the property index is defined.

Specified by:

has in interface Scriptable

Overrides:

has in class ScriptableObject

Parameters:

index - the numeric index for the property

start - the object in which the lookup began

Returns:

true if and only if the property was found in the object

See Also:

Scriptable.get(int, Scriptable), ScriptableObject.getProperty(Scriptable, int)

put

public void put(java.lang.String id,
       Scriptable start,
       java.lang.Object value)

Description copied from class: ScriptableObject

Sets the value of the named property, creating it if need be. If the property was created using defineProperty, the appropriate setter method is called.

If the property's attributes include READONLY, no action is taken. This method will actually set the property in the start object.

Specified by:

put in interface Scriptable

Overrides:

put in class ScriptableObject

Parameters:

id - the name of the property

start - the object whose property is being set

value - value to set the property to

See Also:

Scriptable.has(String, Scriptable), Scriptable.get(String, Scriptable), ScriptableObject.putProperty(Scriptable, String, Object), Context.toObject(Object, Scriptable)

put

public void put(int index,
       Scriptable start,
       java.lang.Object value)

Description copied from class: ScriptableObject

Sets the value of the indexed property, creating it if need be.

Specified by:

put in interface Scriptable

Overrides:

put in class ScriptableObject

Parameters:

index - the numeric index for the property

start - the object whose property is being set

value - value to set the property to

See Also:

Scriptable.has(int, Scriptable), Scriptable.get(int, Scriptable), ScriptableObject.putProperty(Scriptable, int, Object), Context.toObject(Object, Scriptable)

get

public java.lang.Object get(java.lang.String id,
                   Scriptable start)

Description copied from class: ScriptableObject

Returns the value of the named property or NOT_FOUND. If the property was created using defineProperty, the appropriate getter method is called.

Specified by:

get in interface Scriptable

Overrides:

get in class ScriptableObject

Parameters:

id - the name of the property

start - the object in which the lookup began

Returns:

the value of the property (may be null), or NOT_FOUND

See Also:

Context.getUndefinedValue()

get

public java.lang.Object get(int index,
                   Scriptable start)

Description copied from class: ScriptableObject

Returns the value of the indexed property or NOT_FOUND.

Specified by:

get in interface Scriptable

Overrides:

get in class ScriptableObject

Parameters:

index - the numeric index for the property

start - the object in which the lookup began

Returns:

the value of the property (may be null), or NOT_FOUND

See Also:

Scriptable.get(String,Scriptable)

getDefaultValue

public java.lang.Object getDefaultValue(java.lang.Class<?> ignored)

Description copied from class: ScriptableObject

Implements the [[DefaultValue]] internal method.

Note that the toPrimitive conversion is a no-op for every type other than Object, for which [[DefaultValue]] is called. See ECMA 9.1.

A hint of null means "no hint".

Specified by:

getDefaultValue in interface Scriptable

Overrides:

getDefaultValue in class ScriptableObject

Parameters:

ignored - the type hint

Returns:

the default value for the object See ECMA 8.6.2.6.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
