Method Detail

equals

public boolean equals(Object obj)
Overrides:
equals in class Value

hashCode

public int hashCode()
Overrides:
hashCode in class Value

setDefaultValue

public void setDefaultValue(Value value)
Sets the default value of this reference.

Parameters:
value - the default value.

evaluate

public String evaluate(Map symbolTable)
                throws RslEvaluationException
Evaluates the variable reference with the specified symbol table. The value of the reference is first looked up in the symbol table. If not found, then the default value is used. If the default value is not specified, the reference is evaluated to an empty string.

Overrides:
evaluate in class Value
Parameters:
symbolTable - the symbol table to evaluate the variabled reference against.
Returns:
an evaluated string.
Throws:
RslEvaluationException - If an error occured during rsl evaluation.

toRSL

public void toRSL(StringBuffer buf,
                  boolean explicitConcat)
Produces a RSL representation of this variable reference.

Overrides:
toRSL in class Value
Parameters:
buf - buffer to add the RSL representation to.
explicitConcat - if true explicit concatination will be used in RSL strings.

getCompleteValue

public String getCompleteValue()
Returns a complete string representation of this value.

Overrides:
getCompleteValue in class Value
Returns:
a complete string representation of this value.

toString

public String toString()
Overrides:
toString in class Value
