Class ComplexEntityExpression

java.lang.Object

de.aristaflow.adept2.core.orgmodelmanager.parser.EntityExpression

de.aristaflow.adept2.core.orgmodelmanager.parser.ComplexEntityExpression

public class ComplexEntityExpression
extends EntityExpression

A ComplexEntityExpression connects two or more EntityExpressions, i.e. they themselves can be ComplexEntityExpressions too. How these sub expressions are connected is determined by its type (getType()).

This class is used for the object-based representations of OrgPolicies created by the parser.

Constructor Detail

ComplexEntityExpression

public ComplexEntityExpression(ComplexEntityExpression.Type type)

Constructs a new (and empty) ComplexEntityExpression of the given type.

Parameters:

type - the type of the complex entity expression

Method Detail

getType

public ComplexEntityExpression.Type getType()

Returns the type if this ComplexEntityExpression.

Returns:

the type if this ComplexEntityExpression

getSubExpressionCount

public int getSubExpressionCount()

Returns the number of sub-expressions contained in this complex entity expression.

Returns:

the number of sub-expressions contained in this complex entity expression

getSubExpressionAt

public EntityExpression getSubExpressionAt(int index)

Returns the sub-expression at the given index.

Parameters:

index - the index of the sub-expression to be returned

Returns:

the sub-expression at the given index

addSubExpression

public void addSubExpression(EntityExpression entExp)

Appends the given expression to this complex expression.

Parameters:

entExp - the (atomic or complex) expression to be appended

replaceSubExpressionAt

public void replaceSubExpressionAt(int index,
                                   EntityExpression entExp)

Replaces the sub-expression at the given index with the given expression.

Needed (internally) for path completion.

Parameters:

index - the index of the expression to be replaced

entExp - the expression to replace the other one

format

public void format(java.lang.StringBuilder s)

Description copied from class: EntityExpression

Formats this object-based representation of an entity expression to a (policy) string. The result is appended to the given StringBuilder.

Specified by:

format in class EntityExpression

Parameters:

s - the StringBuilder to which the result is appended
