Constructor Details

SFVec4f

public SFVec4f()

Default public constructor required by Rhino for when created by an Ecmascript call.

SFVec4f

public SFVec4f(float[] vec)

Construct a field based on the given array of data (sourced from a node).

Parameters:

vec -

SFVec4f

public SFVec4f(double[] vec)

Alternate constructor that takes a double array rather than a float array. Used primarily by the VrmlMatrix code.

Parameters:

vec -

Method Details

jsConstructor

public void jsConstructor(double x,
 double y,
 double z,
 double w)

Constructor for all three values that rhino calls.

Parameters:

x - The X component of the vector

y - The Y component of the vector

z - The Z component of the vector

w - The W component of the vector

has

public boolean has(int index,
 org.mozilla.javascript.Scriptable start)

Check for the indexed property presence. Always returns NOT_FOUND as ECMAScript doesn't support indexed objects.

Specified by:

has in interface org.mozilla.javascript.Scriptable

Overrides:

has in class FieldScriptableObject

Returns:

has

public boolean has(String name,
 org.mozilla.javascript.Scriptable start)

Check for the named property presence.

Specified by:

has in interface org.mozilla.javascript.Scriptable

Overrides:

has in class FieldScriptableObject

Parameters:

start -

Returns:

true if it is a defined eventOut or field

get

public Object get(int index,
 org.mozilla.javascript.Scriptable start)

Get the variable at the given index. Since we don't support integer index values for fields of the script, this always returns NOT_FOUND.

Specified by:

get in interface org.mozilla.javascript.Scriptable

Overrides:

get in class FieldScriptableObject

Returns:

get

public Object get(String name,
 org.mozilla.javascript.Scriptable start)

Get the value of the named function. If no function object is registered for this name, the method will return null.

Specified by:

get in interface org.mozilla.javascript.Scriptable

Overrides:

get in class FieldScriptableObject

Parameters:

name - The variable name

start - The object where the lookup began

Returns:

the corresponding function object or null

put

public void put(int index,
 org.mozilla.javascript.Scriptable start,
 Object value)

Sets a property based on the index.

Specified by:

put in interface org.mozilla.javascript.Scriptable

Overrides:

put in class FieldScriptableObject

Parameters:

index - The index of the property to set

start - The object who's property is being set

value - The value being requested

put

public void put(String name,
 org.mozilla.javascript.Scriptable start,
 Object value)

Sets the named property with a new value. A put usually means changing the entire property. So, if the property has changed using an operation like e = new SFColor(0, 1, 0); then a whole new object is passed to us.

Specified by:

put in interface org.mozilla.javascript.Scriptable

Overrides:

put in class FieldScriptableObject

Parameters:

name - The name of the property to define

start - The object who's property is being set

value - The value being requested

jsFunction_add

public SFVec4f jsFunction_add(org.mozilla.javascript.Scriptable newVector)

Add this vector to the given vector and return the value as a new vector.

Parameters:

newVector - The vector to add to this vector

Returns:

The addition of the two objects

jsFunction_cross

public SFVec4f jsFunction_cross(org.mozilla.javascript.Scriptable newVector)

Calculate the cross product of this vector and the given vector

Parameters:

newVector - The vector to do the cross product with

Returns:

The product

jsFunction_divide

public SFVec4f jsFunction_divide(double n)

Divide this vector by the given scalar value and return the result in a new vector

Parameters:

n - The scalar to divide the objects by

Returns:

The addition of the two objects

jsFunction_dot
