Specified by:

isGrounded in interface AbsObject

Overrides:

isGrounded in class AbsObjectImpl

Returns:

true if the object is grounded.

getJavaClass

public static java.lang.Class getJavaClass()

isMetaTerm

public final boolean isMetaTerm()

Return true if this object represents a meta term (i.e. symbol ??x) rather than a concrete variable. This method is currently used only by the semantics framework.

Returns:

true if this object represents a meta term

Since:
