Method Detail

createExpression

Expression createExpression(String path,
                            ExpressionOperatorTypes.BINARY_OPERATOR operator,
                            Object value)
                     throws FilterOptionException

Creates a binary expression that comprises of a PropertyNode, LiteralNode, and the operator. For example, Name eq 'John'. In this example, PropertyNode contains Name, LiteralNode contains 'John', and the operator is 'eq'.

Parameters:

path - Name of the property

operator - Binary operator used to form the expression

value - Literal value used in the expression

Returns:

An Expression object containing the binary expression

Throws:

FilterOptionException - If an error occurs while creating the binary expression

createExpression

Expression createExpression(Expression left,
                            ExpressionOperatorTypes.BINARY_OPERATOR operator,
                            Expression right)
                     throws FilterOptionException

Creates a binary expression by combining two child expressions with an operator.

Parameters:

left - One of the child expressions used to build the binary expression

operator - Binary operator used to form the final expression

right - One of the child expressions used to build the binary expression

Returns:

An Expression object containing the final binary expression

Throws:

FilterOptionException - If an error occurs while creating the binary expression

not

Expression not(Expression filter)

Prepends the not operator to the expression. For example, not (Name eq %27John%27).

Parameters:

filter - Expression to be negated

Returns:

Expression with the not operator prepended to it

and

Expression and(Expression left,
               Expression right)

Joins two expressions using the and binary operator.

Parameters:

left - One of the child expressions used to build the binary expression

right - One of the child expressions used to build the binary expression

Returns:

An Expression object containing the final binary expression
