Method Detail

setOperator

public void setOperator(int oper)

Sets the relation operator.

Parameters:

oper - the relation operator.

getOperator

public int getOperator()

Returns the relation operator.

Returns:

the relation operator.

getOperatorAsString

public java.lang.String getOperatorAsString()

Returns the relation operator as a string.

Returns:

the relation operator as a string.

getOperatorAsString

public static java.lang.String getOperatorAsString(int op)

Returns a string representation of the specified relation operator.

Parameters:

op - the relation operator

Returns:

the string representaion of the relation operator.

add

public void add(Value value)

Adds a value to the list of values.

Parameters:

value - the value to add.

add

public void add(java.lang.String strValue)

Adds a value to the list of values. The string value is first converted into a Value object.

Parameters:

strValue - the value to add.

add

public void add(java.lang.String[] strValues)

Adds an array of values to the list of values. Each element in the array is converted into a Value object and inserted as a separate value into the list of values.

Parameters:

strValues - the array of values to add.

add

public void add(java.util.List list)

Adds a list to the list of values. It is inserted as a single element.

Parameters:

list - the list to add.

getValuesAsStrings

public java.util.List getValuesAsStrings(boolean includeNested)

getValuesAsString

public static java.util.List getValuesAsString(java.util.List values,
                                               boolean includeNested)

toRSL

public void toRSL(java.lang.StringBuffer buf,
                  boolean explicitConcat)

Produces a RSL representation of this relation.

Specified by:

toRSL in class NameValue

Parameters:

buf - buffer to add the RSL representation to.

explicitConcat - if true explicit concatination will be used in RSL strings.

evaluate

public NameOpValue evaluate(java.util.Map symbolTable)
                     throws RslEvaluationException

Evaluates the relation against the symbol table.

Parameters:

symbolTable - the symbol table to evalute the relation against.

Returns:

a new evaluted relation.

Throws:

RslEvaluationException - If an error occured during rsl evaluation.
