Constructor Details

CompoundTermImpl

public CompoundTermImpl(Object[] term)

Construct a compound term from an Object array. In this constructor the functor (which should be a String) is passed in as element 0 of the array parameter, the other arguments, which can be instances of any Java classes/interfaces representing ECLiPSe types, are the remaining elements of the array. The arity is therefore the size of the array - 1.

CompoundTermImpl

public CompoundTermImpl(String functor,
 Object[] args)

Construct a compound term from a String and an Object array. User supplies functor and an array of argument objects. Arity of the resulting compound term is args.length.

CompoundTermImpl

public CompoundTermImpl(String functor,
 Object a1)

Convenience constructor for compound terms with arity 1.

CompoundTermImpl

public CompoundTermImpl(String functor,
 Object a1,
 Object a2)

Convenience constructor for terms with arity 2.

CompoundTermImpl

public CompoundTermImpl(String functor,
 Object a1,
 Object a2,
 Object a3)

Convenience constructor for compound terms with arity 3.

CompoundTermImpl

public CompoundTermImpl(String functor,
 Object a1,
 Object a2,
 Object a3,
 Object a4)

Convenience constructor for compound terms with arity 4.

CompoundTermImpl

public CompoundTermImpl(String functor,
 Object a1,
 Object a2,
 Object a3,
 Object a4,
 Object a5)

Convenience constructor for compound terms with arity 5.

Method Details

arg

public Object arg(int i)

Return one of the term's arguments. These may be instances of any Java class/interface representing an ECLiPSe type.

Specified by:

arg in interface CompoundTerm

Parameters:

i - the argument index. This may vary between 1 and arity() inclusive.

argCT

public CompoundTermImpl argCT(int i)

Return the argument at position i, as a CompoundTermImpl. This operation is the same as arg, except that it tries to cast the result to a CompoundTermImpl. Useful for extracting nested objects: eg. a = result.argCT(1).argCT(3).argCT(3);

Parameters:

i - may vary between 1 and arity()

toString

public String toString()

Overrides:

toString in class Object
