getClauses in interface Clause

Returns:

child clauses if the clause has any, empty list if it has none.

getOperand

public Operand getOperand()

Specified by:

getOperand in interface TerminalClause

Returns:

the right hand side value of the expression. This can be a composite of more Operands or it can be SingleValueOperands that resolve to constant values.

getOperator

public Operator getOperator()

Specified by:

getOperator in interface TerminalClause

Returns:

the operator used by the clause Operator.

getField

public String getField()

Specified by:

getField in interface WasClause

getPredicate
