Class AbsIRE

java.lang.Object

jade.content.abs.AbsObjectImpl

jade.content.abs.AbsIRE

All Implemented Interfaces:

AbsContentElement, AbsObject, AbsTerm, ContentElement, Term, Serializable

public class AbsIRE
extends AbsObjectImpl
implements AbsContentElement, AbsTerm

An Abstract descriptor that can hold an Identifying Referential Expression (IRE). Note that an IRE is both a content element (as in the case of a QUERY-REF communicative act) and a Term (as in the case of (== (X) (iota ?x P(?x))

Constructor Detail

AbsIRE

public AbsIRE(String typeName)

Construct an Abstract descriptor to hold a IRE of the proper type (e.g. ANY, IOTA, ALL...).

Parameters:

typeName - The name of the type of the IRE held by this abstract descriptor.

Method Detail

setVariable

public void setVariable(AbsVariable variable)

Sets the variable of this IRE.

Parameters:

variable - The abstract descriptor holding the variable.

setVariables

public void setVariables(AbsAggregate variables)

Sets the sequence of variables of this IRE.

Parameters:

variables - The abstract descriptor holding the sequence of variables.

setTerm

public void setTerm(AbsTerm t)

Sets the variable term of this IRE.

Parameters:

t - The abstract descriptor holding the variable or sequence of variables.

setProposition

public void setProposition(AbsPredicate proposition)

Sets the proposition of this IRE.

Parameters:

proposition - The abstract descriptor holding the proposition.

getVariable

public AbsVariable getVariable()

Gets the variable of this IRE.

Returns:

the abstract descriptor holding the variable of this IRE.

getVariables

public AbsAggregate getVariables()

Gets the sequence of variables of this IRE.

Returns:

the abstract descriptor holding the sequence of variables of this IRE.

getTerm

public AbsTerm getTerm()

Gets the variable term of this IRE.

Returns:

the abstract descriptor holding the variable term of this IRE.

getProposition

public AbsPredicate getProposition()

Gets the proposition of this IRE.

Returns:

the abstract descriptor holding the proposition of this IRE.

isGrounded

public boolean isGrounded()

Redefine the isGrounded() method in order to always return false. Infact an IRE always includes a variable.

Specified by:

isGrounded in interface AbsObject

Overrides:

isGrounded in class AbsObjectImpl

Returns:

true if the object is grounded.

See Also:

AbsObject.isGrounded()

getJavaClass

public static Class getJavaClass()

isAContentExpression

public boolean isAContentExpression()

Description copied from interface: AbsContentElement

Return true if this Abstract Content Element represents a ContentExpression of the SL Grammar (see also FIPA-SL specifications).

Specified by:

isAContentExpression in interface AbsContentElement

Returns:

true if this Abstract Content Element represents a ContentExpression of the SL Grammar (see also FIPA-SL specifications), false otherwise

See Also:

AbsContent.isAContentExpression

setIsAContentExpression

public void setIsAContentExpression(boolean flag)

Description copied from interface: AbsContentElement

Set the isAContentExpression flag to the passed value. By default, if this method was not called, this value is intialized to false.

Specified by:

setIsAContentExpression in interface AbsContentElement

Parameters:

flag - true if this Abstract Content Element represents a ContentExpression of the SL Grammar (see also FIPA-SL specifications), false otherwise

See Also:

AbsContent.setIsAContentExpression(boolean flag)

getAbsType

public int getAbsType()

Specified by:

getAbsType in interface AbsObject

Overrides:

getAbsType in class AbsObjectImpl
