Constructor Detail

ExistsStatementImpl

public ExistsStatementImpl()

ExistsStatementImpl

public ExistsStatementImpl(org.antlr.runtime.Token token)
Method Detail

accept

public void accept(INRLAstVisitor visitor)
Description copied from interface: INRLAstNode
Accept a visitor to this node.

Specified by:
accept in interface INRLAstNode
Overrides:
accept in class Antlr3NRLBaseAst
Parameters:
visitor - the visitor

dump

@Deprecated
public String dump(int indent)
Deprecated. 

Description copied from interface: INRLAstNode
Dump the AST and its children for debugging purposes

Specified by:
dump in interface INRLAstNode
Overrides:
dump in class Antlr3NRLBaseAst
Parameters:
indent - the indentation count, 0 on first call
Returns:
the AST as a string

getConstraint

public IConstraint getConstraint()
Description copied from interface: IExistsStatement
Return the constraint to check relative to each collection member being iterated over. Use IExistsStatement.hasConstraint() to check if it exists first.

Specified by:
getConstraint in interface IExistsStatement
Returns:
the constraint or null

getCount

public ICardinalityConstraint getCount()
Description copied from interface: IExistsStatement
Return the cardinality constraint (one, two, three, at least one, etc.), if there is one. Else returns null. Call IExistsStatement.hasCount() to check first.

Specified by:
getCount in interface IExistsStatement
Returns:
the cardinality constraint or null

getElement

public IModelReference getElement()
Description copied from interface: IExistsStatement
Return the model reference being checked for existence. Never returns null.

Specified by:
getElement in interface IExistsStatement
Returns:
the model reference

getLine

public int getLine()
Description copied from interface: INRLAstNode
Return the line in the input file where this node occurred.

Specified by:
getLine in interface INRLAstNode
Specified by:
getLine in interface org.antlr.runtime.tree.Tree
Overrides:
getLine in class Antlr3NRLBaseAst
Returns:
the line, 1-based

getColumn

public int getColumn()
Description copied from interface: INRLAstNode
Return the column in the input file where this node occurred.

Specified by:
getColumn in interface INRLAstNode
Overrides:
getColumn in class Antlr3NRLBaseAst
Returns:
the column, 1-based

hasConstraint

public boolean hasConstraint()
Description copied from interface: IExistsStatement
Return true if there is a constraint attached that is to be executed relative to collection members.

Specified by:
hasConstraint in interface IExistsStatement
Returns:
true if a constraint is attached

hasCount

public boolean hasCount()
Description copied from interface: IExistsStatement
Return true if the exists statement has a counter attached to it.

Specified by:
hasCount in interface IExistsStatement
Returns:
true if there is a counter

setElement

public void setElement(ModelReferenceImpl element)
