Fields

SFNode [in, out] metadata NULL [X3DMetadataObject]

Information about this node can be contained in a MetadataBoolean, MetadataDouble, MetadataFloat, MetadataInteger, MetadataString or MetadataSet node.

Hint

SFBool [in] set_boolean

set_boolean is the input value to be filtered.

Warning

  • It is an error to define this transient inputOnly field in an X3D file, instead only use it a destination for ROUTE events.

SFBool [out] inputTrue

inputTrue only passes a true value, which occurs when set_boolean input is true.

Hint

  • inputTrue is an output event that can only provide a value of true.

SFBool [out] inputFalse

inputFalse only passes a false value, which occurs when set_boolean is false.

Hint

  • inputFalse is an output event that can only provide a value of false.

SFBool [out] inputNegate

inputNegate is an output event that provides an opposite value by negating set_boolean input.
