Constructor Detail

AbsObjectImpl

protected AbsObjectImpl(String typeName)

Construct an Abstract descriptor to hold an object of the proper type.

Parameters:

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

Method Detail

getTypeName

public String getTypeName()

Specified by:

getTypeName in interface AbsObject

Returns:

The name of the type of the object held by this abstract descriptor.

See Also:

AbsObject.getTypeName()

set

protected void set(String name,
                   AbsObject value)

Sets an attribute of the object held by this abstract descriptor.

Parameters:

name - The name of the attribute to be set.

value - The new value of the attribute. If value is null the current mapping with name (if any) is removed.

getAbsObject

public AbsObject getAbsObject(String name)

Gets the value of an attribute of the object held by this abstract descriptor.

Specified by:

getAbsObject in interface AbsObject

Parameters:

name - The name of the attribute.

Returns:

value The value of the attribute.

See Also:

AbsObject.getAbsObject(String)

getAbsObject

protected AbsObject getAbsObject(int index)

This method enables all order-based getter methods in AbsPredicate

getValues

protected AbsObject[] getValues()

This method enables the omonimous method in AbsPredicate

getNames

public String[] getNames()

Specified by:

getNames in interface AbsObject

Returns:

the name of all attributes.

See Also:

AbsObject.getNames()

isGrounded

public boolean isGrounded()

Tests if the object is grounded, i.e., if no one of its attributes is associated with a variable

Specified by:

isGrounded in interface AbsObject

Returns:

true if the object is grounded.

See Also:

AbsObject.isGrounded()

getCount

public int getCount()

Gets the number of attributes.

Specified by:

getCount in interface AbsObject

Returns:

the number of attributes.

See Also:

AbsObject.getCount()

toString

public String toString()

This method is here just for debugging. Notice that it is highly innefficient. The method StringCodec.encode() should be used instead.

Overrides:

toString in class Object

equals

public boolean equals(Object obj)

Returns true if the attribute is equal to this abstract descriptor, based on the contents of both descriptors.

Overrides:

equals in class Object

hashCode

public int hashCode()

Returns an integer hashcode calculated from the contents of this abstract descriptor

Overrides:

hashCode in class Object

getAbsType

public int getAbsType()

Specified by:

getAbsType in interface AbsObject
