Method Summary
`void`	`add(Binding binding)` Adds a new variable definition to the list.
`Bindings`	`evaluate(Map symbolTable)` Evaluates the variable definitions as variable definitions can reference each other against the symbol table.
`boolean`	`removeVariable(String varName)` Removes a specific variable definition from the list of bindings.
`void`	`toRSL(StringBuffer buf, boolean explicitConcat)` Produces a RSL representation of this relation.

Constructor Detail

Bindings

public Bindings(String attribute)

Method Detail

add

public void add(Binding binding)

Adds a new variable definition to the list.

Parameters:: binding - a new variable definition.

removeVariable

public boolean removeVariable(String varName)

Removes a specific variable definition from the list of bindings. The variable name must match exactly to be removed (it is case sensitive).

Parameters:: varName - variable name to remove the definition of.
Returns:: true if the variable was successfully removed. False, otherwise.

evaluate

public Bindings evaluate(Map symbolTable)
                  throws RslEvaluationException

Evaluates the variable definitions as variable definitions can reference each other against the symbol table. The evaluation process updates the symbol table.

Parameters:: symbolTable - the symbol table to evalute the variables against.
Returns:: a new evaluted variable definition.
Throws:: RslEvaluationException - If an error occured during rsl evaluation.

toRSL

public void toRSL(StringBuffer buf,
                  boolean explicitConcat)

Produces a RSL representation of this relation.

Overrides:: toRSL in class NameValue

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